This architectural drawing is Aluminum Expansion Guide Clamp with Zinc-Plated Steel design in AutoCAD 2D drawing, dwg file, CAD file. For industrial installations with big diameter cables in long span circumstances, ITray's aluminum I-beam design is ideal because it reduces total tray width and creates a seamless transition between straight sections and fittings. Strong, mid-span splices with fewer supports are produced by a structural offset in the sidewall. The amount of hardware required is reduced by 50% because to the fact that each splice snaps into place and stays in place without holding. For more details and information download the drawing file.
