I-Beam Clamp for Ceiling Mounts

The Peerless ACC558 clamps directly onto an overhead I-beam to anchor a compatible ceiling mount. Its adjustable width spans 4" to 8" and the height adjustment ranges from .25" to 1". A 1 1/2-11.5 NPS threaded fitting provides the connection point for the mount hardware. It suits installers who need a structural attachment without drilling into concrete or wood.

Sustained Load Capacity of 250 lb

The clamp is rated for a maximum static load of 250 lb, meaning it supports the full weight of the mounted display and bracket continuously. The steel construction and fused epoxy coating maintain their grip and finish under that constant tension. There is no separate burst or dynamic rating provided, so the 250 lb figure represents the working limit for permanent installations.

Scratch-Resistant Epoxy Finish and Adjustable Jaws

The black fused epoxy coating resists scratches during installation and daily exposure, preserving the professional appearance in visible ceiling spaces. The adjustable clamping interface accommodates flange widths between 4" and 8" and flange thicknesses up to 1", allowing a secure fit on standard I-beam profiles without shims or modifications. Buyers who need to mount to concrete ceilings or unistrut channels will require a different anchor system.

Questions about this item

How much heat or noise does the ACC558 generate during continuous use?

The clamp is a passive steel accessory with no moving parts, so it produces no heat and makes no noise while supporting a mounted display.

What existing hardware is required to attach the ACC558 to a ceiling mount?

You need a Peerless ceiling mount that uses a 1 1/2-11.5 NPS threaded fitting to connect the clamp to the I-beam.

Will the ACC558 fit the 4-inch to 8-inch flange on my older building's I-beam?

Yes, the adjustable width spans exactly 4" to 8" and the height adjusts from 0.25" to 1", matching common legacy beam dimensions.
