SPRENGER ratchet block with clam cleat
1193*17 Kugelgelagerter Knarrblock SPRENGER
SPRENGER ratchet block with clam cleat
Lockable swivel shackle.
Plastic (HOSTAFORM C) housing with stainless steel fittings.
The angle of the cleat is adjustable.
Ratchet blocks can significantly reduce the load on the hauling part of the sheet, because the ratchet roller (in a 3-sheve block the middle roller) can be blocked during slacking.
In light wind the ratchet can be switched off to allow the block to turn both ways.
With the ratchet on, the sheet purchase has 8 times as much power as when running free.
The high quality of the blocks made by the manufacturer HERM.SPRENGER (HS) and the good price to performance ratio have been emphasized in a number of professional journals.
