Barton T04131 – TUPHblox Single Swivel Block with Becket 58mm, Brass Bearing, Max Rope 14mm
The Barton T04131 TUPHblox Single Swivel Block with Becket is part of the heavy-duty 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 operating conditions.
The block runs on brass bearings for smooth and reliable operation, while 316 marine grade stainless steel bindings ensure corrosion resistance and structural integrity. The swivel head allows free rotation under load, reducing line twist and improving alignment, while the integrated becket enables secure rope termination in purchase systems.
Tufnol construction provides non-conductive properties, making this block ideal for industrial environments, including explosive zones and hot air balloon systems. The laminated structure ensures long service life, high durability, and excellent resistance to UV exposure and weathering.
