The 30mm Dynamic Triple Block with Inverted Cleat and Becket is a versatile and essential component of any sailing system. This block, featuring an inverted allenite cam cleat with pro-lead, is ideal for ending a purchase system and securely holding the rope. The included becket makes tying off easier and helps keep the load central. Our patented bearing system, which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail, offers superior load-carrying abilities and longevity when compared to other bearing systems. Additionally, the patented Ultra-Strap used in our 20, 30 & 40mm Dynamic blocks is uniquely designed with a coining process to strengthen the strap and make it more reliable, hard-wearing, and rope-friendly. It was the first marine industry block specifically designed to work with a rope attachment.
