Harken Stand-up Bases allow a wide variety of blocks to be held upright, swivel freely, or pivot so lines have a fair lead under load.

Ball-and-Socket Swivel Bases
The ball-and-socket design lets blocks articulate up to 45 degrees and swivel freely. The 460 and 461 bases have stainless steel reinforcement plates to handle the high load capacities of 57 mm and 75 mm Carbo blocks. Harken Stand-Up Bases may be fitted with springs, but blocks won’t hit the deck without them.

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.

Midrange Cruising ESP Stand-Up
Use the 1634 Harken Stand-Up Base with Midrange blocks and 57 mm or 75 mm Cruising ESP blocks. Block headpost fits into socket without shackle. The low-profile design is ideal for mastbase and halyard lead blocks.


Springs support blocks on padeyes, eyestraps, bases, and traveler cars, and prevent blocks from hitting the deck.

Stand-Up Boots
Made of durable, flexible PVC, stand-up boots hold blocks up without snagging lines. The 369 fits 40 mm and 57 mm Carbo and Black Magic® blocks. The 370 fits 75 mm Carbo blocks.
