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