Stand-Up Bases & Stand-Up Springs

Stand-Up Bases & Stand-Up Springs
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.

Mid-range Stand-Up

Use the 1573 stand-up base with Mid-range blocks. The low-profile design is ideal as a mastbase halyard lead block. Combine the 1573 with single Mid-range ratchet or Fiddle blocks. Doubles and triples will fit the 1573, but their safe working loads are higher than the base.

Springs

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