DMM Climbing

Founded in 1981 as Moorhouse Engineering in Bethesda, soon to become DMM and move to more suitable premises in Llanberis in 1986, the company celebrated 30 years of manufacturing 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.

The original premise of the founding Directors was to make the best possible equipment at the best price. A simple premise you might think, but one that has remained central to our thinking over the intervening years, and one that has spurred us on to continue to develop and innovate, to bring unique and world leading products to the market.

From the very outset the company has developed products in two main areas; Recreational Climbing and Mountaineering has developed alongside products aimed more at the more Industrial markets. Both areas compliment each other and the areas of overlap benefit both sides.
