stopper deck block

The sheaves are made of high strength resin, fitted with composite fibre bush and side ball-bearings. No maintenance or lubrication is required.

The machined side plates are made of high strength alloy, hard black anodized for wear and corrosion proofing and with all the edges smoothed off.

The aluminium locking cam is fitted on an automatic opening spring: relaxing the sheet is sufficient to open the jammer.

Compact design with the lever fully concealed within the side plates and with recessed fasteners.
  The cam cannot be locked under high loads. It’s intended to hold the line temporarily and not under heavy loads.

Left and right versions are available.
