The ITW Grimloc™ Locking D-Ring can be used on any 1" wide piece of webbing and replaces the metal carabiner for attachment of lanyards, weapons, and accessories. The Grimloc is fabricated from high strength lightweight plastic, incorporates GhillieTex™ IR-signature reduction technology, and resists solar heating. Its latch is designed with a detent to maintain an open position if needed and, while strong enough to carry equipment, it will break away with a soldier's weight, eliminating snagging hazards which can cause serious injuries. The release button is textured for ease of use with gloved hands and works as a pump for purging trapped sand or water through integral drain holes. Pack contains four (10) GRIMLOC D-Rings.
