Our product line of adjustable frames enables you to change the frame dimension without having to switch out the inserts. Overall shipping dimensions are kept to a minimum by shipping the frames in telescoped-in position.

Good to know!
Alltec adjustable frame inserts match the standardized flange pattern of Alltec adjustable spreader bars. Our spreader bar end-caps can be bolted onto the frame inserts. In other words, (1) adjustable frame consisting out of (4) adjustable inserts, can be easily transferred onsite into (4) adjustable spreader bars.
