Description

RONSTAN RF55171 SERIES 55BB ORBIT UPRIGHT LEAD BLOCK (2 1/8″ SHEAVE : 3/8″ LINE)

Just by looking at this Series 55 Ball Bearing Orbit upright block, it nearly impossible not to realize that Ronstan is leaps and bounds ahead of all other manufacturers in the design and manufacturing of blocks!
Like all other Ronstan blocks, this lightweight block has the highest working loads in its class. It features Ronstan’s 2-stage bearing system with high compression grade black Acetal carbon black ball bearings and a secondary full-contact bearing to provide minimal friction across the full working load range; a toughened, glass reinforced frame; a carbon fibre-reinforced, PTFE-impregnated Nylon sheave; and style.
Use it for mainsheet and spinnaker sheet systems on dinghies, sportsboats, and small keelboats; halyard, vang, and backstay applications on boats up to 26′ (8m); and control line applications on larger yachts.
