This Series 55 Ratchet Orbit triple block has single intermediate cheeks and an ultra- light and efficient head arrangement to provide you with a 30% weight savings advantage over the nearest competitor.

This block utilizes Ronstan's orbital ball-bearing arrangement to create the largest possible race diameter and maximize load performance. It also takes advantage of Ronstan's two-stage bearing system to provide minimum friction across the full working load range.

Use it for mainsheet and spinnaker systems on dinghies, sportboats, and small keelboats. Make it part of your halyard, vang, and backstay applications on boats up to 26' (8m) and for control line applications on larger yachts.
