Rope Cutters

R&D Marine Rope Cutters

Made of 316L Stainless Steel.
Unique design to stop ropes jamming between the cutlass bearing and rope cutter.
Smooth cutting action which avoids vibrations or shock commonly associated with scissors style cutters.
Radial and axial holes in the cutter allow water flow and propeller performance.
No moving parts to service or fail.
Installs in minutes with minimum of tools.

Supplied with bolts, hex keys, drill, thread lock and full fitting instructions.

How to choose your rope cutter:

  1. Measure the shaft diameter. This needs to be carried out accurately. Some imperial sizes are very close to metric sizes.
  2. Measure the cutlass bearing housing diameter
  3. Measure the space available for fitting the cutter.
