This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.  Ultra-Strap Ð Our patented Ultra-Strap is used in our 20, 30 \u0026amp; 40mm Dynamic blocks. The Ultra-Strap is unique when compared to other designs because of its coining process. This process strengthens the strap, making it more reliable and hard-wearing as well as making it much more rope friendly than other designs. The Ultra-Strap was the first marine industry block designed to work specifically with a rope attachment.","brand":"Allen Brothers","offers":[{"title":"Default Title","offer_id":50447360131381,"sku":"ALL-A2024-677","price":127.13,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/0392\/1461\/files\/ALL-A2024-677_200x200_90bef504-ac1c-42c3-bd38-7f63260abfaf.jpg?v=1753054907","url":"https:\/\/senditsailing.com\/products\/allen-20mm-dynamic-triple-block-with-inverted-cleat","provider":"SendIt Sailing","version":"1.0","type":"link"}
