The BBB60 Single Becket Heavy Duty Block is designed for heavy load applications. The 60 mm sheave is supported by stainless steel ball bearings and stainless ballbearing races, reducing friction and enhancing durability. Acetal bearing cages to prevent ball-to-ball friction and to reduce weight. 

The block includes a becket for rigging versatility and a plastic washer serving as a swivel lock, allowing the shackle to be locked at 0° or 90°. The glass fiber reinforced cheeks offer added strength, making this block ideal for control line applications on larger keelboats.
