Spinlock BRS 50mm Jamming Spinnaker Block

An excellent choice for situations where a fixed foot block just won't do, the Spinlock BRS 50MM Jamming Spinnaker Block provides controlled spinnaker handling in a range of conditions. This block is equipped with a locking cam, making it ideal for changing sheet winch, sail changes and locking spinnaker sheets upwind. The locking cam can be tuned to the exact rope size ranging from 6 to 10 millimeters. It features a plain bearing sheave for smooth running at low loads and has a rugged composite and alloy construction for excellent durability at high loads. This Spinlock jammer block from Atlantic Rigging Supply requires no drilling and can be attached via a webbing strop, which is positioned on a toe rail or padeye, helping to eliminate clutter on the deck.
