Grimloc™ Locking D-ring When the United States Marine Corps was looking for a new fastener for their bladder hydration system they came to ITW. ITW had recently delivered the first IR signal reducing hardware, GhillieTEX™, and the Marines new that they could count on us. The existing hydration units utilized a shoulder strap system that was prone to ridding over the body armor and cutting of circulation to the arms at the shoulder and pinching nerves. Marines in the 1 MEF began to ask for a system that would allow them to fasten their hydration system directly to their body armor.
The Grimloc™ Locking D-ring was the solution. Around this time the Army was also looking for a fastening solution to mount items directly to the MOLLE webbing found on rucksacks, body armor, and load bearing vests. The army was interested in a solution that was strong enough to carry equipment that required quick access yet would "break away" with a Soldiers weight. Often Soldiers would mount lanyards directly to the MOLLE webbing, or to large metal Carabineers utilized in climbing. These methods would not allow for a quick break if the lanyard was snagged jumping and could result in serious injury to the soldier.
