A2058 - Allen 50mm Triple Block with Ratchet & Adjustable Cleat.
The A2058 is a high-performing ball-bearing ratchet block, ideal for use on Keelboats and Catamarans for a range of applications from mainsheet to backstay tensioning systems.
The 50mm triple is a great choice for systems which require a larger purchase system with minimal friction.
Switchable Ratchet – The middle sheave of this block is a 50mm ratchet sheave. The ratchet can be turned on and off, even while under load, with the easy to use switch located either side of the block.
Adjustable Cam Cleat – Adjust the cleating angle to suit your application by loosening and sliding the cam cleat rail to the desired location.
Anti-Snag – Anti-snag elastic to stop the line from getting wrapped underneath the cam cleat.
Bearings – This block features our patented dynamic 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.
Swivel Lock – The A2058 comes with a removable swivel lock moulding. When installed, the shackle can be locked in 90-degree orientations. When removed, the attachment shackle can spin freely.
Becket – This pulley features a central becket between the sheaves. The becket can be removed by undoing the split ring. This allows for easy termination of a spliced rope.
