The key to a star performance is control.

We worked with professionals from the entertainment industry to make the design improvements on winches most needed in theatre operation. Among the resulting products is the Thern Clew Winch which can conveniently raise and lower light and scenery batons, either with or without counterweights. Our clew winches install easily, provide dependable control and – with a large, 5-9/16 inch diameter drum – help extend the life of the wire rope.
