Allen Brothers Sailing Hardware
With more than 60 years of engineering experience, Allen Brothers has become one of the most respected names in sailing hardware. Their products are widely used across racing fleets, training boats, cruising yachts and performance sailing applications.
The Allen range includes blocks, cleats, sheaves, deck organisers, adjusters, rigging screws, pad eyes, spinnaker hardware and rigging accessories designed to deliver smooth and dependable performance.
Dynamic Bearing Technology
Many Allen blocks feature patented Dynamic Bearing Technology, using twin rows of stainless steel ball bearings running on stainless steel bearing tracks. This design delivers low friction performance, smooth line handling and excellent load carrying capability.
Dynamic blocks are ideal for applications where control lines require frequent adjustment and responsive sail trimming.
Ultra Strap Technology
Allen’s patented Ultra Strap Technology uses a narrow stainless steel strap that allows blocks to be lashed securely while helping reduce line abrasion. The lightweight design provides excellent strength while keeping overall rigging weight to a minimum.
