Selden Blocks

Blocks made for perfect interaction
Seldén blocks give you the benefits of a high strength to weight ratio. We only use top quality materials like composite, 50/50 glass fibre/polyamide and marine grade stainless steel. Each component is designed for top performance and perfect interaction with the rig under all conditions. The bearing cage design of the ball bearing blocks is a typical example of functional Seldén design. It not only lowers block weight, but also further reduces friction. The Seldén block range consists of plain bearing blocks, ball bearing blocks, high load ball bearing blocks, high load plain bearing blocks and ratchet blocks.
