Mule Blocks

Thern Stage Equipment mule blocks offer convenient installation while ensuring a smooth, quiet operation for your performance.

Product Description

Our mule block is a single or multi-groove sheave that supports and changes the direction of one or more cables traveling between loft and head blocks. This block redirects the load path of wire rope around obstructions. It’s ideal for any overhead rigging system where an obstructed load path is present or where corrections are required to meet fleet angle requirements. Our mule blocks include customized mounting options to meet your specific application. All Thern Stage Equipment 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. We guarantee consistent service life for your Thern Stage Equipment mule block by offering a two-year limited warranty to make sure that you’re 100% satisfied.
