Combat Economy Full Body Harness
Frontline's Combat Series harness is the economy go-to that crews keep stocking: safety-orange polyester webbing, universal sizing that fits most users, and the OSHA and ANSI compliance every site walk verifies. The 100VMB is the minimalist configuration - a single dorsal fall-arrest D-ring, adjustable leg straps, and a pass-through mating buckle - at just 2.25 lb, the lightest economy harness in the lineup.
Safety orange polyester with alloy steel (golden yellow / silver galvanized finish) hardware. Rated to a 310 lb capacity and 5,000 lb breaking strength. Compliant with ANSI Z359.11-2014 and A10.32-2004 and OSHA 29 CFR 1910 and 1926. Sold as a 3-pack — three complete harnesses ship together for $119.
Who Needs This Product
This product is a personal fall protection full body harness. It is used as the wearer-side component of a personal fall arrest system (PFAS), a work positioning system, or a fall restraint system. Pair it with a compatible energy-absorbing lanyard or self-retracting lifeline (SRL) and a certified anchor rated to 5,000 lb. The harness is not a complete fall arrest system on its own.

Typical Applications
Donning Overview
Single-operator donning per the Frontline user manual. Always refer to the manual for the full procedure.
- Inspect. Run the harness through a pre-use inspection: webbing, hardware, stitching, labels, fall indicators.
- Orient. Hold the harness up by the dorsal D-ring. Shake the leg straps free so they hang clean.
- Shoulders. Slip both arms through the shoulder straps with the dorsal D-ring centered between the shoulder blades.
- Chest. Connect the chest buckle. Adjust so the strap sits 6 to 8 inches below the collarbone.
- Legs. Pass each leg strap under the thigh and connect at the leg buckle. Tighten until two fingers fit between strap and thigh.
- Tighten. Adjust shoulders, chest, and legs evenly. The dorsal D-ring should rest between the shoulder blades, not riding up the neck or down the lower back.
Inspection and Retirement
Inspect every component before each use. A competent person inspects formally on a documented interval, typically every 6 months under ANSI Z359.2. Pull the equipment out of service for any of the conditions below.
- Webbing: cuts, burns, abrasion, chemical attack, broken threads, loose stitching.
- Hardware: cracks, deformation, sharp edges, corrosion, improper function of buckles and D-rings.
- Stitching: cut, broken, or loose stitches; pulled threads at any load point.
- Labels: legible and intact. Date of first use recorded.
- Fall indicators: any deployed or stretched indicator pulls the equipment out of service immediately.
- Connectors and hooks: gates close fully under spring tension; latches lock; no rollout exposure.
Retirement triggers: any deployed fall indicator, any equipment involved in a fall event, any chemical exposure outside the manufacturer-published list, or any condition where the inspector cannot positively verify the equipment is fit for service.
