Item #DMM-0222

This top quality lightweight, dual stemmed cam has proved to be very popular, and it is easy to see why. The 4CU is quick and easy to place; it also offers stable secure protection across a variety of crack features.

There are 9 different sizes in the range which fit a huge array of crack shapes and sizes, in fact anything from half an inch (13mm) to a meaty 4 inches (100mm). The most commonly used sizes of 1, 1.5 and 2; just what you need for dealing with that awkward crack width that runs between rattley finger jams, to ring locks and on to narrow hand size.

There are lots of interesting technical details which give 4CUs the edge on other double stemmed cams. Some of this might seem a bit techy, but it really will make a difference to how the cam performs at the crag. The free floating, peened axle for example reduces stress and helps to avoid a sheering torque at the point of impact.

The cam lobes work on the original 13.75° camming angle which gives the best balance between holding power and range. And the cam stops allow a (10kN) strength even when placed passively.

As with all of our cam designs, the 4CUs are fitted with double extendable dyneema slings. This means neat storage and quick and easy extension if you need it.

We've made the trigger bar free-floating so it can slide on the trigger wires. This reduces wear and tear on the wires and means you won't have to worry about replacing them each season.
