Product Number: 503
Hard hats only protect when they stay on the head. A loose helmet during overhead work, on windy sites, or when leaning into an engine bay is exactly when an accidental knock dislodges the shell. The Sealey 503 chin strap solves that - designed to fit the Worksafe® 502 range of vented safety helmets, securing the shell to the head during all the situations a free-fit hard hat won't survive. The strap fits as an accessory to an existing helmet; the helmet shell itself is sold separately. For compatibility with any non-502 helmet, please refer to the product label for guidance, or contact Parts for Machines for confirmation. Backed by Worksafe's guarantee in addition to your statutory rights.
