Your cart is empty.Founded in 1981 as Moor house Engineering in Bethesda, soon to become DMM and move to more suitable premises in Llanberis in 1986, the company celebrates 30 years of manufacturing this year in 2011. In 1981 the company employed just 4 people and now thirty years later we are an important employer in this area with just over 150 men and women on payroll.

My climbing partner has the black diamond nuts and I have these. Between the two, I think I prefer the DMM shape. They just seem more secure more often than the BD ones. Also- had a friend whip on the 11 and it held! Climb on!
