Harken Stand Up Bases

Stand-up bases allow a wide variety of blocks to be held upright, swivel freely, and pivot for fairleads under load.

Ball and Socket Swivel Bases
The ball and socket design allows blocks to swivel freely and pivot to a 45 degree angle. Bases may be fitted with springs but block won’t hit the deck without them. Select blocks carefully as the maximum working load of either base is often less than corresponding blocks.

Stanchion Mount Base
The 061 stanchion mount base attaches blocks to 7/8 in or 1 in (22 or 25 mm) stanchions or pulpits and is often used to lead furling lines to the cockpit. Allows blocks to swivel and pivot for fairleads.


Springs
Springs are used to support blocks on padeyes, eyestraps, bases and traveler cars. Keeps blocks from hitting the deck.
