Allen 50mm Dynamic Quint Block with Switchable Ratchet and Adjustable Cleat.

Ideal for use on Keelboats and Catamarans for a range of applications from jib sheet to mainsheet systems, to backstay tensioning systems and everything in between. Pair with the A2059 for a complete system.

Adjustable Cam Cleat Arm‚ The cam cleat angle can be adjusted by undoing the bolt and sliding the cam cleat on the track up or down. Re-tighten the bolt into one of the new location holes to keep the cleat arm in position.

Bearings‚ Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems available on the market.

Custom Fairlead‚ The A2159 features a custom fairlead which has been designed to allow easy cleating of the mainsheet when pulled from the trapeze. It also gives minimal friction, to ensure you can play the mainsheet harder for longer.

Becket ‚ The becket is removable for customisation of purchase systems.
