Allen 50mm Pro Single Switchable Ratchet Block

Allen 50mm Pro Single Switchable Ratchet Block

AutoRatchet Blocks

The clever internal mechanism is designed to activate when the block is under load - as every sailor knows this can make all the difference on a long spinnaker reach or upwind beat.  Ratchet blocks are engineered with ball bearing technology and advanced engineering polymers for longevity and performance.

Switchable Ratchet Blocks

These blocks have a ratchet mechanism that can easily be switched on or off even under load and the swivel head can be locked in a fixed position. Allen sheave technology gives you grip under load and easy release when the load is decreased.
