Specialty Underhung Loft Blocks

Specialty loft blocks are used when unusual mounting conditions exist. Series 44 pivot blocks are used when the support structure is not installed level. Series 46 and 47 swivel blocks are used when the lift lines are not run perpendicular to the support. Each rigid steel housing contains a single-groove sheave rotating on sealed precision ball bearings. Each series 44 pivot block and 46 swivel block is fabricated to fit a specific beam size. Offset clips and mounting bolts are supplied for attachment to the support structure. Beam flange width and thickness must be specified at time of ordering.
