The rockD Lanyard Pin carabiner helps prevent gear from moving past the end of the carabiner. When the potential for dangerous leverage or cross-loading can occur, the removable stainless steel pin keeps the carabiner oriented correctly, and the gear where it belongs. The Lanyard Pin is available on the rockD in 3 stage auto-lock. rockD FRAME CHARACTERISTICS Narrow asymmetric "D" shape optimizes MBS High strength-to-weight ratio in standard size carabiner Snag-resistant keylock nose design Large and ergonomic angled gate opening Machined frame ensures tight tolerances and smooth operation
