Allen Pro-Ratchet 50 with Cleat and Becket.

Ratchet blocks feature an internal ratcheting mechanism which only allows the sheave to turn in one direction. This gives the user more control to make incremental adjustments to hand-held lines such as jib sheets, spinnaker sheets and mainsheets.

Adjustable Cam Cleat: An A..76 cam cleat is mounted to an adjustable arm to allow easy adjustment of the cleating angle.

Becket: This block features a removable becket, so spliced rope can be easily attached or removed.

Anti-Snag: Included is an anti-snag elastic line which stops your line from getting caught between the cleat and block.

Switchable: In the middle of the block is a switch that can be used, even under load, to turn the ratchet mechanism on or off. Giving you more control and feel of your control system.

Extreme Hold: The Pro-Ratchet 50 features a hardwearing nylon sheave with eight V grips to give extreme holding power on all lines.
