Established in 1981 as Moorhouse Engineering in Bethesda, later becoming DMM and moving to Llanberis in 1986, the company hit its 40-year milestone in 2021. Their founders aimed to create top-quality gear at great prices, a principle that still guides them today.

They focus on two main areas: climbing gear for fun and safety, and industrial gear for work. Both sides help each other out, making both parts of the business equally important for the future.
