Ring-Nub® is an open spherical low-friction ring that withstands very high loads and is available for strings from 3 mm to 12 mm maximum.
Ring-Nub offers a unique combination of advantages in terms of performance, durability and ease of use. It's an excellent choice for applications where friction must be minimized and strength maximized.
Description
+ Use
High load in dynamic use
-
3D headsail adjustment
- Backstay and tackle
- Cascade for boom downhaul
- Double sheet forwarders
- Deck plates & tackle
... just about everything!
- Ideal for reefing, cascade hoisting (backstay, vang, backstay), corner return, or even cap-de-mons on standing rigging (shrouds, sub-boom).
- Easily installed anywhere on deck, chainplate, jib rail, mast foot...thanks to our various Dyneema® textile connectors.
