Barton T00130 – TUPHblox Single Swivel Block 20mm, Brass Bearing, Max Rope 8mm
The Barton T00130 TUPHblox Single Swivel Block is part of the compact and durable TUPHblox range, designed 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 corrosion resistance and structural integrity. The swivel head allows the block to rotate freely under load, reducing line twist and improving alignment in dynamic rigging systems.
Tufnol construction provides non-conductive properties, making this block suitable for industrial environments, including explosive zones and hot air balloon systems. The laminated and heat-compressed structure ensures long service life, high durability, and excellent resistance to UV exposure and weathering.
