Tighten, tension, and securely lock serious loads up to 280lb. Made of durable, cast aluminum, the CamJam XT holds cords from 1/16"-3/16" (2mm-5mm) in width, and comes in a combination package with a 16' (4.88m) length of 550 paracord. Its carabiner clip and gate on one end and rotating cam mechanism on the other allows you to anchor the carabiner to any hook, D-ring, or loop, and feed the cord through the cam until you've reached the desired level of tension. Pull the cord firmly and the cam locks into place and stays that way until you release it by rotating the cam and pulling up on the cord.
