Harken Standard Cam Base Swivel

Ball bearing swivel bases feature dual rows of Delrin ball bearings that swivel freely even under high loads. Bases include stand-up springs and a U-adaptor to accept a variety of appropriate blocks. The 144 is the standard configuration with a tall arm. It is ideal for mounting in the cockpit or for use on larger keelboats and small offshore boats that use 3.00 in (76 mm) plastic blocks. Used on the Melges 24.
