What Sets the 100CTB Apart
●
Dorsal D-Ring for Fall ArrestSingle alloy steel D-ring centered between the shoulder blades. Primary fall arrest attachment. Two dorsal fall arrest indicators deploy visibly and permanently if the harness is loaded in arrest.
▲
Integrated Suspension Trauma StrapsTwo trauma relief pouches mount on the waist belt. Deploys post fall to give the suspended worker footholds that shift leg position and maintain blood circulation while awaiting rescue.
●
Two Side D-Rings for Work PositioningHip D-rings on the work positioning belt are tested per ANSI Z359.11 section 3.2.6 for work positioning and travel restraint only. Used as a pair. Not rated for fall arrest, that is the dorsal only.
■
Fall Arrest Indicators (FAI)Two FAIs sit at the dorsal area. INSPEC confirmed both deploy visibly and permanently following dynamic feet-first and head-first dorsal arrest testing. Retire the harness immediately if either deploys.
◆
Alloy Steel Hardware, Galvanized FinishAll D-rings, buckles, and connectors are galvanized alloy steel with a Golden Yellow and Silver finish. The automatic chest buckle has a PCB finish. Built for abrasive construction environments.
✦
Moisture-Wicking PaddingBack, shoulder, and waist pads use breathable, moisture-wicking material. Reduces fatigue and heat exhaustion on long shifts. Built for roofing, high-rise, and summer construction work.
★
Tongue Buckle Leg StrapsTraditional tongue buckle on both leg straps. Secure, field-adjustable, easy to inspect. Grommets protect the webbing at buckle contact points. INSPEC measured eyelet spacing of 1.8 in, within the 1.125 in to 2.0 in ANSI range.
◉
Color-Contrasting StitchingOrange thread on black polyester webbing. Contrasting colors make pre-use webbing inspection fast. Broken stitching is visible at a glance. Webbing width 1.73 in (44 mm tested, above the 41 mm ANSI minimum).
▲
Padded Work Positioning BeltThe work positioning belt supports a full tool load without the harness sagging. Distributes load through the waist while the worker is suspended at the hips. Lanyard keepers on the shoulder straps keep your connector organized.
✓
5-Point AdjustabilityFive points of adjustment allow a snug, customized fit across all four sizes. Reduces pressure points and harness migration during long shifts. All adjusters passed INSPEC static testing with no slippage.
☀
Ironwork, Roofing, and Steel Erection ReadyFrontline built the Combat Series for sustained construction wear: ironworkers, steel erectors, formwork crews, roofers, and standing seam metal roof installers. Built for the shift.
■
Lanyard Keepers and ParkingTwo integrated lanyard parking attachments. INSPEC measured 94.4 lb disengagement load, below the 120 lb maximum permitted by ANSI Z359.11 section 3.1.10. Unused legs stay parked, release cleanly under fall force.
Attachment Points: Know Before You Clip In
The 100CTB has three D-ring locations. Each is rated for specific uses only. Never use a positioning D-ring for fall arrest.
Fall ArrestDorsal D-Ring (Back)Centered on the vertical midline between the shoulder blades. Primary fall arrest attachment. Also approved for travel restraint and rescue. Connect your SRL or shock-absorbing lanyard here for any fall arrest application.
Work Positioning OnlySide D-Rings (Hip, Pair)Two alloy steel side D-rings on the work positioning belt. Used as a pair for work positioning and travel restraint only per ANSI Z359.11 section 3.2.6. Not rated for fall arrest.
Lanyard ParkingLanyard Parking AttachmentTwo lanyard parking locations on the shoulder straps secure unused lanyard legs. INSPEC measured disengagement at 94.4 lb, under the 120 lb maximum per ANSI Z359.11 section 3.1.10.

Size Selection
Size is based on both height and weight, not weight alone. All four sizes share 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) | 4 ft 10 in to 5 ft 6 in | 110 lb to 170 lb |
| Medium / Large (M/L) | 5 ft 2 in to 6 ft 4 in | 140 lb to 260 lb |
| XL / 2XL | 5 ft 4 in to 6 ft 8 in | 200 lb to 310 lb |
| 3XL / 4XL | 5 ft 10 in to 6 ft 10 in | 240 lb to 310 lb |
⚠ Weight Capacity: Read Before Ordering
310 lb 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 total system limit.
If a worker's combined weight exceeds 310 lb but is under 400 lb, the employer is required by OSHA 1926.502(d)(16) to modify criteria and protocols to provide appropriate protection. Above 400 lb a higher-capacity harness system is required.

How to Don the Harness in 7 Steps
A correctly fitted harness is as important as a certified one. Follow these steps every time before moving to height.
- Shake it out. Hold the harness by the dorsal D-ring and shake to let any tangled straps fall into place.
- Unbuckle everything. Unbuckle the automatic chest buckle, tongue-buckle leg straps, and waist belt before putting on.
- Slip over shoulders. Slip the straps over the shoulders so the dorsal D-ring is centered between the shoulder blades on the vertical midline.
- Connect the chest buckle. Position in the mid-chest area and engage the automatic buckle. Adjust the shoulder straps at the lower-end adjusters so left and right are equal length.
- Thread the leg straps. Pull each leg strap between the legs and engage the tongue buckle on the opposite side. Connect the waist belt last.
- Adjust for snug fit. After all buckles are connected, adjust so the harness fits snug but allows full range of motion. Confirm no fall arrest indicator is deployed.
- Confirm the anchor point. Use the dorsal D-ring as your fall arrest connection. Verify your lanyard or SRL is properly engaged before moving to height. Check the dorsal FAIs are not deployed before each use.
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 the webbing 6 to 8 inches into a U-shape and inspect all webbing for tears, cuts, fraying, abrasions, burns, holes, mold, or broken stitches. Inspect under keepers and pads. Inspect D-rings and hardware for cracks, distortion, sharp edges, and corrosion on the galvanized finish. Engage and release the chest buckle to confirm positive lock. Confirm neither dorsal Fall Arrest Indicator is deployed. Takes 60 to 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 and made available to all users at all times. The user manual includes a Checking Card for log-in. More frequent inspection is required in heavy-use, abrasive, or chemical environments.
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. The dorsal FAIs will have deployed. Internal webbing fiber damage from a fall event is not visible to the eye.
Retirement for Damage
Remove from service if webbing shows damage, buckles show deformation, hardware shows corrosion beyond the galvanized surface, labels are illegible, or any component fails inspection. Repairs may only be performed by Frontline Fall Protection Inc. or a party authorized in writing by Frontline. Field repair of webbing, stitching, or hardware is not permitted.
Cleaning and Storage
Wipe down with mild detergent and a clean cloth. Wipe dry the alloy steel hardware after cleaning to prevent corrosion. Do not machine wash, dry clean, or use harsh solvents. Store in a cool, dry environment, out of direct sunlight and away from heat sources, chemicals, vapors, and moisture.
Fall Clearance
Fall clearance below the anchor point is set by the lanyard or SRL, not the harness alone. Use the dorsal D-ring height relative to the work surface, the connector's deceleration distance, the harness stretch (Hs), and a safety factor. The Frontline user manual states a maximum Hs of 18 inches for clearance calculations on the 100CTB.
To run the math for your specific connector and anchor height, use our calculator: Fall Protection Clearance Calculator.
Frequently Asked Questions
What is the difference between the 100CTB and the 100RCTB?
The 100CTB and 100RCTB share the same chassis, alloy steel hardware, tongue-buckle leg straps, hip D-rings, work positioning belt, and integrated trauma straps. The 100RCTB adds 360-degree 25 mm reflective tape and uses safety-orange polyester webbing. The 100CTB uses black polyester webbing without reflective tape. The 100CTB was tested by INSPEC (Report 2.21.07.17). The 100RCTB was tested by SATRA (Report SPC0260480/1730/2).
Can the side D-rings be used for fall arrest?
No. The two hip side D-rings are rated and tested for work positioning and travel restraint only, used as a pair per ANSI Z359.11 section 3.2.6. The dorsal D-ring on the back is the only fall arrest attachment point on this harness.
What is the Fall Arrest Indicator and what do I do if it deploys?
Two FAIs are located in the dorsal area and deploy visibly and permanently when the harness is subjected to fall-arrest forces. If you see a deployed indicator, the harness must be immediately removed from service and destroyed. Internal webbing fiber damage from a fall event is not visible to the eye. INSPEC confirmed the indicators deployed correctly during dynamic testing.
What does the 310 lb capacity actually mean?
310 lb is the combined maximum of the user body weight plus everything they are carrying, including clothing, tools, and equipment. If the combined weight exceeds 310 lb but is under 400 lb, OSHA 1926.502(d)(16) requires the employer to modify criteria and protocols. Above 400 lb a higher-capacity harness system is required.
Can I use this harness in Canada?
The 100CTB is certified only to ANSI/ASSE Z359.11-2014. It is not certified to CSA Z259.10. 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 use on Canadian jobsites.
What lab tested the 100CTB and what accreditation do they hold?
The 100CTB was tested by INSPEC Technical Services (Kunshan) Co. Ltd. INSPEC holds ANAB accreditation certificate AT-1725 under the ANSI National Accreditation Board. Testing was conducted 7 June to 29 July 2021. Reference 2.21.07.17, issued 30 July 2021, signed by Steven Sum, Laboratory Manager.
