Allen blocks, also known as pulleys, are all high performing and use a patented Dynamic Bearing technology. Allen also invented and use a patented Ultra-strap technology, a very narrow strap of high strength stainless steel, which can be lashed without fear of line abrasion associated with blocks of traditional strap construction. Throughout the range you can be assured of quality, innovation and performance.
Allen blocks are designed and made here in the heart of Essex where we are based.
