Allen Ratchet Blocks

New for 2019 - More Grip, Less Slip With New Wave Ratchet

AutoRatchet Blocks

Allen were pioneers in the development of the first AutoRatchet blocks more than 30 years ago. 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.  Years of constant development with the world's top sailors has made the AutoRatchet one of the most reliable and effective on the market. All Allen 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. The cheek block allows port or starboard deck mounting. The 50mm switchable ratchet block is ideal for sailors wanting to reduce the size without losing the inherent strength of this design.
