Wooden Block-StandUp-Standard Series

Stand-Up Blocks

For all blocks with swivel fittings, UB Shop offers a Stand-Up Spring Set designed to keep your block upright and in the optimal working position.

Crafted from durable marine-grade stainless steel springs and a solid base, this set prevents your block from tipping or twisting under load. The result is smoother operation, less wear on your rigging, and longer service life.

We can supply the spring set on its own, allowing you to convert an existing swivel block into a stand-up block, or deliver a complete stand-up block ready for installation.
