Use as sheet control blocks on dinghies, or for control lines on larger boats. High-impact Delrin® sheaves turn on polished stainless steel spacers, so the cheeks won't squeeze or bind the sheave, even under extremely heavy loads. Head shackles are stamped stainless steel with a clevis pin and cotter ring. Cheeks are black hard-coated anodized aluminum. Straps, headclips, shackles, and rivets are tumbled and polished stainless steel. A flat, stainless base plate distributes load to a larger surface area than other designs which place loads on mounting bolts only. Use spars and decks to lead sheets, halyards, reefing gear, and any control line requiring a strong, smooth lead. Note: Special Order Only Show more
