Lewmar D1

Lewmar has redefined rope clutch technology with a variable geometry handle and unique grip pattern of dominos that prevents rope fray. This revolutionary new system has been independently tested time and again and has won awards for its innovative framework. The word clutch is often misused, in the opinion of Lewmar. As used by an engineer, a clutch is a reliable holding device with designed-in slippage controlled with a brake foot pedal or lever. When choosing a clutch for a given task, its best to select the size with an upper rope range the size of the line to be belayed. That provides the least slippage and best holding, even though it might not be the best for line abrasion.
