Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Camming Devices - DMM 4 CU Cams

These top quality lightweight, dual stemmed cams have 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.

Available in 11 different sizes in the range which will fit a huge array of crack shapes and sizes, in fact anything from half an inch (13mm) to a meaty 4 inches (100mm). We have even put in two extra intermediate sizes, 1.25 and 1.75, which slot in between 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 DMM's cam designs, the 4CUs are fitted with double extendable dyneema slings. This means neat storage and quick and easy extension if you need it.

The trigger bar is also 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.
