Conduit Beam Clamp 250 lb

The Super-Strut 500-SC is a clamp-on conduit support designed for electrical installations. It secures raceways to structural beams without welding or drilling. Each clamp accepts 1/4-20 hardware and measures 1-1/4 in long by 1 in wide. Iron construction provides the necessary rigidity for commercial and industrial job sites.

Replaces Welded Brackets

This beam clamp replaces field-welded or bolted brackets when speed and adjustability matter. The jump is worth it on projects where conduit routing changes during fit-out or where hot-work permits are difficult to obtain. Packaged in quantities of 50, it suits crews running multiple drops across a floor plate.

Sustained Load Behaviour

Rated for 250 lb, the clamp meets ASTM B633 and CSA LR-52208 standards for corrosion resistance and mechanical performance. Iron body and hardware maintain clamping force under continuous conduit weight and vibration. The design resists creep better than light-gauge alternatives during long-term static loading.

Questions about this item

What beam flange thickness does the 500-SC clamp fit?

The clamp uses a 1/4-20 set screw to grip flanges up to the jaw opening; tighten until the beam sits fully against the back stop, which is the step most installers skip.

How do I install the 500-SC beam clamp correctly?

Place the clamp over the beam flange, thread the 1/4-20 set screw in by hand, then torque it with a wrench until the clamp body is flush with the flange — the common error is leaving a gap.

When should I replace the 500-SC beam clamps?

Inspect each clamp after any overload event or if the ASTM B633 zinc coating shows white rust; replace any piece with cracked iron, stripped 1/4-20 threads or visible deformation.
