Allen 60mm Single Pro-Ratchet Block

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. Suitable for boats up to 30ft.

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 60 features a hardwearing nylon sheave with eight V grips to give extreme holding power on all lines.

Swivel Lock – The swivel can be locked in 90-degree orientations via the small black swivel lock at the top of the block. Alternatively, the swivel can be set to spin freely.
