The HARKEN cleat is a high quality cleat.
The different rows of high-strength ball bearings and the precise V-shaped opening limit friction. This greatly facilitates maneuvering.
No need to force: simply quickly lower the wrist to lock the sheet in the jammer and immobilize it exactly at the desired setting or raise the wrist to release it instantly, even under heavy load.
Harken cleats are the only ones that operate under maximum tension.
Cam-Matics® in hardcoat anodized aluminum feature superior power and lifespan for applications requiring permanent adjustments.
Minimum rope Ø (mm) 3 mm
Max rope Ø (mm) 12 mm
Maximum working load (kg)
