Head Blocks

Head blocks offer convenient installation and solid construction to ensure a smooth, quiet operation for your performance.

Our standard head block is a multi-groove Nylatron sheave with cable grooves and one purchase line groove. This block redirects the lift lines from the loft blocks down to the counterweight arbor. It includes underhung or upright mounting with a series of holes to accommodate a wide range of head beam configurations. Custom groove arrangements are also available to meet the needs of your specific project. All our blocks are engineered with an 8:1 design factor and conform to ANSI standards for manual and motorized rigging. Made to last, our components are comprised of durable, heavy-duty materials.
