The Allen A..77 Small Ball Bearing Cam Cleat - The jaw profile is optimised for rope entry and exit reducing wear on rope. Ball bearings and double coil springs gives a super smooth cam action, allowing for a consistent feel every time the rope is cleated. Features die-cast aluminium jaws and base, which results in a higher working load and a more durable finish when compared to the Allenite version. These design features make the aluminium cam cleat perfect for applications which may have a fast-running control line, such as a spinnaker halyard, mainsheet or jib sheet.
