This Harken micro carbo cam cleat can handle 1/8"-1/4" line and has a safe working load of up to 150lbs. Cam matic ball bearing cam cleats engage and release easily, hold securely, and work with a wide range of line types and sizes. Cam teeth are smooth to protect line and because tooth grip is not required to close the pawls. Multiple rows of UV stabilized Delrin ball bearings provide minimal friction for easy line engagement and release, even under high loads. The easy entry system allows line to engage without being drawn through the cam; just pull the line straight down and the cam opens and holds perfectly.
