Abstract
An open web structural support member such as a truss is described whose length may be adjusted in predetermined increments and which employs an incremental adjustment means for adjusting the effective length of the end web in order to compensate for adjustment in the length of the truss to maintain a rigid and stable truss. An apertured chord plate is attached to the upper chord member by a pin placed in a selected one of the adjustment holes in such chord plate for adjusting the length of the truss. The chord plate is connected to a mounting bracket at the end of the upper chord member. The incremental adjustment means for the web includes an adjustable link means connected to an end web member to form an end web assembly of adjustable length attached between the mounting bracket and the lower chord member. This adjustable link means including a first link member of fixed length and a second link member having a plurality of adjustment apertures therein and a connecting bolt which is selectively inserted into one of such apertures to change the length of such link member.
