Crosby McKissick Oilfilled Blocks
These blocks have a painted and galvanized finish. The 8" and 10" blocks are furnished with dual rated wireline sheaves. They have forged steel swivels, tees, yokes and the shackles are quenched and tempered. The recessed side plate design reduces the gap between the sheave rim and the side plate and allows the sheave assembly to be captured in the block if loss of centre pin occurs. The sheave is lubricated through the centre pin for easy maintenance.
