SPRENGER ball bearing blocks with snap shackle

High-quality double sheave violin ball-bearing blocks from the manufacturer SPRENGER with a stainless steel snap shackle as block eye.

Ball-bearing performance (recognizable by the small red dot on the side) for all fast-running lines and for uses in which exceptionally smooth running is required (for example, a mainsheet in light winds).
The blocks are equipped with stainless steel ball bearings.

Simple black housing made from high-quality UV- and saltwater-resistant HOSTAFORM C plastic.
All fittings and bolts are of stainless steel.

The high quality of the blocks made by the manufacturer SPRENGER (HS) and the good price to performance ratio have been emphasized in a number of professional journals.
