The lightest construction harness of its kind. The Frontline 110CTB Combat™ Lite replaces every steel hardware component — D-rings, buckles, and adjusters — with drop-forged aluminum, delivering the same 5,000 lb breaking strength at a total harness weight of just 5.8–6.0 lbs. Add built-in suspension trauma straps, moisture-wicking padding, two side D-rings for work positioning, and a back web loop adapter for twin-SRL placement, and you have a harness built for contractors who put real hours on their gear. Certified ANSI/ASSE Z359.11-2014, compliant with OSHA 1910 and 1926. Tested by INSPEC Technical Services — ISO/IEC 17025:2017 accredited, ANAB certified (AT-1725).

What Sets the 110CTB Apart
◆
100% Aluminum Hardware Every metal component — dorsal D-ring, side D-rings, chest buckle, and all adjusters — is drop-forged aluminum. Full 5,000 lb breaking strength at roughly half the weight of equivalent steel hardware.
▲
Integrated Suspension Trauma Straps Deploys post-fall to give the suspended worker footholds to shift leg position, maintaining circulation and helping prevent orthostatic hypotension while awaiting rescue.
■
Two Side D-Rings for Work Positioning Hip D-rings rated and tested for work positioning and travel restraint. Tested as a pair per ANSI Z359.11 §3.2.6 — static feet-first test passed on all three specimens.
◉
Dual Fall Arrest Indicators (FAI) Two FAIs deploy visibly and permanently after any fall event at the dorsal attachment. Visual confirmation that the harness has been loaded — must be retired immediately per OSHA and ANSI requirements.
●
Back Web Loop for Twin SRL Dedicated back web loop adapter allows twin-leg self-retracting lanyard placement, keeping the dorsal D-ring free for rescue use or alternate connection configurations.
✦
Moisture-Wicking Padding Back, shoulder, and waist pads use breathable, moisture-wicking material. Reduces fatigue and heat exhaustion on long shifts — especially relevant for roofing and summer construction work.
◆
Quick-Connect Chest Buckle The dual-tab release mechanism prevents accidental disengagement. Tugging on both halves confirms a locked connection — fast to don, secure once engaged.
■
Color-Contrasting Stitching High-tenacity polyester webbing (1.73" width) with color-contrasting stitching makes pre-use webbing inspection fast — damaged or frayed stitching is visible at a glance. Webbing width exceeds the 41mm ANSI minimum.
▲
Reinforced Belt & Rigid Pad Supports a full tool belt without the harness sagging or shifting during the day. Integrated tool-tether loops and shoulder-strap lanyard keepers keep your system organized underfoot.
★
Extreme Temperature Rated Designed for use in temperatures from -40°F to +130°F (-40°C to +54°C). Performs in Canadian winters and summer roofing conditions across the full North American climate range.
●
Tongue Buckle Leg Straps Traditional tongue buckle on both leg straps — secure, field-adjustable, and easy to inspect. Grommets protect the webbing at buckle contact points to prevent wear.
✓
Abrasion-Tested Webbing Strap tensile tests passed both pre- and post-abrasion conditioning per ANSI Z359.11 §3.3.1. 5,000 lb pre-abrasion, 3,600 lb post-abrasion — both passed the full one-minute load hold.
Attachment Points — Know Before You Clip In
The 110CTB has three D-ring locations. Each is rated and labeled for specific uses. Never use a positioning ring for fall arrest.
Fall Arrest Dorsal D-Ring (Back) Centered on the vertical midline between the shoulder blades. Primary fall arrest attachment point. Also approved for travel restraint and rescue. Connect your SRL or shock-absorbing lanyard here for fall arrest applications.
Work Positioning Only Side D-Rings (Hip — Pair) Two aluminum side D-rings on the work positioning belt. Rated and tested for work positioning and travel restraint only. Must be used in pairs per ANSI requirements. Not rated for fall arrest.
Twin SRL Back Web Loop (Upper Back) Dedicated attachment point for placing a twin-leg SRL lanyard. Keeps the dorsal D-ring available for rescue attachment. Lanyard parking attachment elements tested and passed ANSI §3.1.10 — disengagement loads 85–90 lb, well within the 120 lb maximum.

Size Selection
Size is based on both height and weight — not weight alone. All four sizes have the same 310 lb maximum capacity. Measure before ordering. A harness worn on a jobsite cannot be returned.
| Size | Height Range | Weight Range |
|---|---|---|
| Small (S) | 5'0" – 5'7" | 110 – 175 lbs |
| Medium/Large (M/L) | 5'3" – 6'1" | 130 – 250 lbs |
| XL/2XL | 5'7" – 6'3" | 200 – 310 lbs |
| 3XL/4XL | 5'9" – 6'5" | 250 – 310 lbs |
⚠ Weight Capacity — Read Before Ordering
310 lbs is the maximum combined weight of the user including all clothing, tools, and equipment carried. This is not a body weight limit — it is a system limit.
If the combined tool and body weight of a worker is between 310 lbs and 400 lbs, the employer is required by OSHA 1926.502(d)(16) to modify the criteria and protocols to provide appropriate protection. The system will not be deemed in compliance without these modifications. ANSI capacity range is 130–310 lbs (59–140.6 kg).
Compliance & Certification
✔ Certified ANSI/ASSE Z359.11-2014 Full body harness standard for personal fall arrest systems. Dorsal dynamic feet-first, head-first, and static tests all passed. Fall Arrest Indicator and Hip static tests passed.
✔ Compliant OSHA 1926.502 & 1910.140 Meets OSHA requirements for personal fall arrest in both construction (1926) and general industry (1910). Required for all US regulated work at height.
⚠ Canadian Buyers — Note CSA Z259.10 — Not Certified The 110CTB is ANSI certified only. Most Canadian provincial OH&S regulations require CSA Z259.10 certification for regulated work at height. Verify with your site safety officer or provincial authority before ordering for use on Canadian job sites. ANSI equivalency must be formally approved.

Right Harness. Right Job.
Metal Roofers Every pound removed from hardware compounds across a full season of ridge walks and ladder climbs. The aluminum difference is felt by lunch on day one.
Long-Shift Crews Workers logging 8–10 hour days in harness benefit most from lighter gear. Fatigue reduction means better decisions at the end of the shift when most falls happen.
Tower & Industrial Vertical climbing applications where the harness weight is felt on every rung. The extreme temperature rating (-40°F to +130°F) handles any North American jobsite climate.
US & Canadian Work ANSI Z359.11 certified for all US applications. Canadian buyers must verify that ANSI equivalency is accepted at their specific worksite — most provinces require CSA Z259.10.
How to Don the Harness — 7 Steps
A correctly fitted harness is as important as a certified one. Follow these steps every time.
- Shake it out. Hold the harness by the dorsal D-ring and shake it to let any tangled straps fall into place.
- Unbuckle everything. Unbuckle the chest, leg, and waist straps before putting on. If the harness has a belt, unbuckle it too.
- Slip over shoulders. Slip straps over shoulders so the back D-ring is centered between shoulder blades on the vertical midline.
- Connect the chest strap. Position in the mid-chest area, then adjust the shoulder straps at the lower-end adjusters. Left and right should be of equal length.
- Thread the leg straps. Pull the end of one leg strap between the legs and secure it to the opposite end. Repeat on the other side. Connect the waist belt after the leg straps.
- Adjust for snug fit. After all buckles are connected, adjust so the harness fits snug but allows a full range of movement. No load indicators should be deployed.
- Confirm the anchor point. Use the dorsal D-ring as your fall arrest connection. Look for the "A" marking near approved attachment points. Verify your lanyard or SRL is properly connected before moving to height.
Inspection & Retirement
Per ANSI Z359.2, full-body harnesses require inspection at two levels. Skipping either is an OSHA violation and a safety failure.
- Pre-use inspection (every use): Bend webbing 6–8 inches into a U-shape and inspect for tears, cuts, fraying, abrasion, burns, holes, mold, or broken stitches. Adjust all keepers, buckles, and padding to inspect hidden webbing. Check D-rings and hardware for cracks, distortion, sharp edges, and corrosion. Confirm the dual-tab quick-connect buckle engages properly — tug both halves. Confirm no Fall Arrest Indicators are deployed. Takes 60–90 seconds. Do it every time.
- Competent Person inspection (minimum every 6 months): Formal documented inspection by a Competent Person who is not the regular user. Records must be maintained. More frequent inspection is required in heavy-use or harsh-environment applications.
- Immediate retirement after any fall: Any harness subjected to fall-arrest forces — even if it appears undamaged — must be removed from service and destroyed immediately. Internal webbing fiber damage is not visible. Both FAIs will have been deployed; this confirms that the harness is retired.
- Retirement for damage: Remove from service if any webbing shows damage, buckles show deformation, hardware shows corrosion, labels are illegible, or any component fails inspection criteria.
- Cleaning: Wipe down with mild detergent (e.g., laundry detergent) and a clean cloth. Wipe hardware with a dry cloth to remove grease or dirt. Do not machine wash, dry clean, or use harsh solvents.
- Storage: Store in a cool, dry environment, out of direct sunlight and away from heat sources, chemicals, vapors, and moisture. Do not store damaged equipment with equipment approved for use.
Frequently Asked Questions
Is aluminum hardware as strong as steel for fall arrest?
Yes. ANSI Z359.11 requires the same 5,000-lb minimum tensile strength for aluminum D-rings as for steel D-rings. The INSPEC test report confirms that the 110CTB’s dorsal D-ring passed dynamic feet-first and head-first tests, as well as static tests, under full ANSI load requirements. The difference between aluminum and steel hardware is weight — approximately 1–2 lbs across a full harness — not load capacity or rated strength.
What are the side D-rings for — can I use them for fall arrest?
No. The two side hip D-rings are rated and tested for work positioning and travel restraint only. They must never be used for fall arrest. They are tested and labeled as hip attachment elements per ANSI Z359.11 §3.2.6, which explicitly restricts hip D-rings to positioning and travel restraint applications.
What are the Fall Arrest Indicators and what do they mean?
The 110CTB has two Fall Arrest Indicators (FAIs) near the dorsal D-ring. They are designed to deploy visibly and permanently when the harness is subjected to fall arrest forces. If you see a deployed FAI, the harness has been loaded in a fall and must be removed from service and destroyed immediately — regardless of how it otherwise appears. This is an OSHA and ANSI requirement, not optional.
What does the 310 lb capacity actually mean?
310 lbs is the combined maximum of your body weight plus everything you’re carrying — clothing, tools, equipment, and accessories. It is not a body weight limit. If the combined weight exceeds 310 lbs but is under 400 lbs, OSHA 1926.502(d)(16) requires the employer to modify criteria and protocols. Above 400 lbs, this harness is unsuitable; a higher-capacity system is required.
Can I use this harness in Canada?
The 110CTB is certified only to ANSI/ASSE Z359.11-2014. It is not certified to CSA Z259.10. Most Canadian provincial occupational health and safety regulations require CSA Z259.10 certification for regulated work at height, including in Ontario, British Columbia, Alberta, and Quebec. Before purchasing for Canadian jobsite use, verify the applicable provincial standard with your site safety officer, prime contractor, or provincial OH&S authority. ANSI equivalency must be formally and explicitly approved in advance.
What is the operating temperature range?
The 110CTB is designed for use from -40°F to +130°F (-40°C to +54°C). This covers the full North American climate range — from Canadian winter conditions to summer roofing work in the southern US. Do not expose the harness to temperatures outside this range, open flames, welding sparks, or direct heat sources.
How do I select the right size?
Size is based on both height and weight — not weight alone. Refer to the size chart above: Small for 5’0"–5’7" / 110–175 lbs; M/L for 5’3"–6’1" / 130–250 lbs; XL/2XL for 5’7"–6’3" / 200–310 lbs; 3XL/4XL for 5’9"–6’5" / 250–310 lbs. All four sizes have the same 310 lb maximum capacity. Harnesses worn on a jobsite cannot be returned — if you’re between sizes, call us before ordering.
Do you help spec complete fall protection systems?
Yes — this is one of the core reasons contractors choose us over a big-box distributor. We stock standing-seam roof anchors, lanyards, and full fall-protection systems. Call before you order, and we’ll make sure the harness, connector, and anchor you select work correctly together for your specific application and roof type.
