Answer:
The 1390024 harness is built with heavy-duty polyamide webbing in a two-tone black and blue colour scheme, pass-through mating buckles made of 45C stamped and zinc-plated steel, and an integrated sub-pelvic sit-strap designed for climbing stability.
The 3M PROTECTA FIRST 1390024 incorporates specialized industrial materials and ergonomics tailored for vertical ascending applications in construction and wind energy environments:
- Webbing Construction: High-tensile polyamide webbing finished in a dual-colour black and blue scheme to facilitate rapid visual orientation and prevent strap twist during donning.
- Metallic Hardware: Leg strap buckles constructed from 45C stamped and zinc-plated steel, delivering corrosion resistance and mechanical strength under dynamic loading. Seat/board hardware components are also zinc-plated steel.
- Buckle Mechanism: Pass-through mating buckles on both chest and thigh closures that lock securely by feeding the male tab through the female frame slot.
- Sub-Pelvic Support: Fitted with an ergonomically positioned sit-strap beneath the pelvic area to optimize load distribution and worker comfort during suspended positioning or post-fall suspension.
