H500 Arc Flash Harness with Back D-Ring
This is the fall-arrest-focused version of the Miller H500 Arc Flash platform: polyamide webbing certified to ASTM F887 for arc flash resistance up to 40 cal per square centimeter, a dielectric dorsal D-ring, dielectric quick connect buckles, and polyamide front webbing loops, without the side positioning rings of the H5AFC1S.
Certified to ANSI Z359.11-2021 and CSA Z259.10-2018 Class ALR and ALPR, and compliant with OSHA 1926.502, the H5AFC2S is rated for workers up to 420 lb per OSHA and CSA, and 310 lb per the ANSI marking.

S/M fits workers up to 5 ft 10 in and 170 lb, or up to 190 lb at 5 ft 6 in and under. Universal (L/XL) covers the broad middle and is the most popular size. XXL/XXXL fits workers over 6 ft who weigh over 270 lb, and any worker from 350 to 400 lb. Lighter boundary bands are overlap zones where either size fits: size down for a trim fit or up for room over layers. Some Miller spec sheets list these as Size 1 (S/M), Size 2 Universal (L/XL), and Size 3 (2XL and 3XL). Based on the manufacturer's published Miller sizing chart; verify fit per the user manual before first use.
Who Needs This Product
For electrical crews that need arc-rated fall arrest without positioning, the H5AFC2S drops the side rings and the price while keeping every protective element: the arc-rated polyamide webbing, the dielectric hardware, and the inspection-friendly indicators and stitching. Crews that also position on poles and structures should choose the H5AFC1S with side D-rings.
Features
ASTM F887 Arc Rating
Polyamide webbing is certified for arc flash resistance up to 40 cal per square centimeter, staying intact when exposed.
Dielectric Hardware
The back D-ring, torso adjuster, and quick connect buckles are all dielectric, removing conductive paths.
Polyamide Front Loops
Webbing loops at the chest replace metal hardware for frontal connections.
Dielectric Quick Connect Buckles
QC hardware clicks together in seconds with gloves on and releases only with a deliberate two-action press.
Dedicated SRL Web Link
A purpose-built web link at the dorsal position attaches personal SRLs cleanly.
Smart Impact Indicators
Clearly identifiable indicators and a visible stitch pattern make inspections fast and sure.

Arc rating is not a license to contact. The harness protects against arc flash exposure; it does not make contact with energized equipment safe. Follow your minimum approach distances and check the impact indicators before every use.

Typical Applications
Donning Overview
- Hold the harness by the back D-ring and shake it out so the straps hang free without twists.
- Slip the shoulder straps on like a vest, keeping the webbing flat against the body.
- Connect the chest buckle and position the chest strap across the middle of the chest.
- Fasten each leg buckle so the strap allows a flat hand between the strap and the leg, but not a fist.
- Work through all five adjustment points until the dorsal D-ring rests between the shoulder blades, then stow the strap ends.
Full donning and adjustment instructions are in the Miller harness manual linked in the documentation section below.
Inspection and Retirement
Inspect this harness before each use, and have a competent person other than the user formally inspect it at least annually per ANSI Z359.2. Check each point below and record the results on the inspection form linked in the documentation section.
- Webbing: cuts, frays, burns, chemical damage, UV fading, or broken stitching anywhere on the harness.
- Hardware: D-rings and buckles for cracks, corrosion, distortion, or sharp edges.
- Adjusters and keepers: slippage, missing keepers, or strap ends that will not stay stowed.
- Labels: present and legible, including the size, standards, and serial information.
Retirement triggers: any fall arrest event, any webbing or hardware defect found during inspection, or any condition where the inspector cannot positively verify the harness is fit for service.
