The STEELMAN PRO 79380 Insulated Hard Hat / Helmet Headlamp Attachment Clip 4-pack (version 2) is a set of replacement clips for use with all STEELMAN PRO mountable headlamps. Made from durable and resilient spring steel, these clips install quickly and easily and hold tight to the edge of most hard hats and bump caps so you can bring the light where you need it without fear of losing it when your head protection is called on to do its job. Electrically insulated, these clips can protect against damaging electrical arcs of up to 600V. This version of the clip features a shallow V shaped bend that helps it hold onto all styles of hard hats from wide brim helmets and thinner bump caps to heavy-duty models with thick, rolled edges. Insulated metal replacement clip only, plastic holder / bezel is not included.
