MATTHEWS Heavy Duty Telescoping Hangers Single Extension 4 ft

Telescoping Hangers have a very substantial pipe clamp to attach to a lighting grid. The pipe clamp has been slightly offset, to allow the riser or drop down tube to slide up when there is sufficient room between the grid and the ceiling. It is therefore possible for a 4 ft Single Extension Hanger to be able to go from a few inches below the grid to the fully extended 4 feet. This is a single stage hanger. All terminate in 1/2-13 female thread to permit the attachment of several hanging accessories listed below. An XTA Head may be added for even greater versatility. MSE Hangers are engineered with an internal mechanical stop, which will prohibit the Riser from falling through should the lock off knob be inadvertently released. 

This hanger is 4 feet long.
