The Barton T01131 TUPHblox Single Swivel Block with Becket is part of the durable and lightweight TUPHblox range, engineered for marine, industrial, and specialist applications. Manufactured from Tufnol phenolic resin laminate with cotton reinforcement, it delivers excellent strength, durability, and resistance to harsh environments.
The block runs on brass bearings for smooth and reliable operation, while 316 marine grade stainless steel bindings ensure structural integrity and corrosion resistance. The swivel head allows free rotation under load, reducing line twist and ensuring optimal alignment, while the integrated becket enables secure rope termination in compact purchase systems.
