Our High Speed Diamond Snatch Blocks are sheaves in which the cheeks can swivel, allowing the user to place the snatch block on a cable already in place. Diamond snatch blocks are secured with a supplied stainless steel captive pin black passivated shackle. Both of these are 1/4' diamond snatch blocks, 1,400 lbs. working load. On the right is our 4.25 Pulley size; on the left is our 5.625 pulley size. Both pulleys feature double row sealed high speed metric bearings. The pulley groove is sized to pass a 1/4' synthetic rope splice. The cheeks are CNC milled from 6061T6 aluminum billets and are anodized black.
Here are the High Speed pulleys, bearing, and axle used in our Diamond Snatch blocks. Note the HUGE double row High Speed Sealed metric bearing. The axle in the picture is used in both of the blocks; Stainless steel bar stock CNC turned and threaded, then precision centerless ground for a perfect fit.
