Light, strong and stable. DMM's new 4CU cams have it all. Sophisticated machining has allowed them to take away all the fat and keep the strength. With the machined cam stops you can place the unit in the umbrella position with confidence. Doubled Dyneema slings allow you to carry fewer draws and still not suffer rope drag. Single axle with free floating terminations increase stability and help prevent the cams from walking. Best of all, they are so light that you can still get off the ground with a full rack. What are you waiting for?
