The Squids 3150 Buckle Hard Hat Lanyard, made of a high-stretch elastic material, easily secures a hard hat to a worker to prevent the hard hat from falling. It also attaches to other headwear and comes in high-visibility lime. A double-lock plastic buckle attaches to fall protection. The lanyard is ideal for construction, utilities, mining and roofing work.
