Schaefer Stand Up Spring Blocks


Schaefer Stand Up Spring Blocks
Stand Up Swivel Blocks on Springs are designed to be mounted to the Deck; Blocks swivel 360°, tilt in all directions and are supported by a heavy gauge SS spring to prevent contact with the Deck when not under load. Commonly used at the base of the Mast for turning Halyards and Reef lines, sometimes a mainsheet, and especially on the foredeck for the Foreguy.
