Loft Blocks

Thern Stage Equipment loft blocks offer convenient installation and solid construction while ensuring a smooth, quiet operation for your performance.

Product Description

Each lift line in the rigging system requires a loft block to direct the wire rope lift line from a batten over to the head block. Our loft block uses side plates and mounting angles integrated into one solid side piece with a turned Nylatron sheave. They come standard in either sequential multi groove or single groove with 2” idlers. All Thern Stage Equipment blocks are engineered with an 8:1 design factor and conform to ANSI standards for manual and motorized rigging. Sealed precision ball and tapered roller bearings are also available.

Made to last, our components are comprised of durable, heavy-duty materials. We guarantee consistent service life for your Thern Stage Equipment loft block by offering a two-year limited warranty to make sure that you’re 100% satisfied.
