Series 40 Ball Bearing Block- Fiddle- Becket- Cleat

Compact design and exceptionally high working loads of Series 40 blocks make them ideal for mainsheet, halyard, vang and spinnaker control applications on boats such as off-the-beach catamarans, one design classes and sports boats up to 26 ft. (8 meters). Also suitable for control lines on larger boats. Captive Lock universal heads allow the blocks to be fixed in either of two planes, or free to swivel as required. Becket pins are removable so lines can be spliced prior to fitting, and are ingeniously locked into position without the use of clevis pins, split rings or tools. Shackles have slotted pins to avoid fouling lines. Double and triple blocks can be locked at 0 or 90. Materials: Acetal ball bearings, UV stabilized Acetal sheaves, UV stabilized Zytel cheeks, and 316 stainless steel load straps and head fittings. Sheave Dia.: 1-9/16" (40mm) Max.
