7"-12" I-Beam Clamps

The Peerless-AV ACC559 is an adjustable I-beam clamp designed to anchor a Peerless-AV ceiling mount to an overhead I-beam. Identified for 7-inch to 12-inch I-beams, it combines cold-rolled steel construction, a 250 lb maximum load capacity, and a threaded connection for integrating compatible Peerless-AV extension columns into an indoor ceiling-mounted system.

Ideal Use Cases

This clamp is intended for indoor installations where an overhead I-beam must serve as the attachment point for a Peerless-AV ceiling mount. It supports both mounting columns and ceiling mounts, making it suitable for configurations built around compatible Peerless-AV extension columns.

The adjustable mounting function accommodates installation requirements without requiring a dedicated ceiling plate. The product name identifies compatibility with 7-inch to 12-inch I-beams, while the technical specifications separately list an 8-inch maximum adjustable width. Project dimensions should therefore be checked against the product specification sheet before installation.

Why Choose This Model

The ACC559 provides a purpose-built connection between an overhead I-beam and a Peerless-AV ceiling mounting system. Its 1 1/2-11.5 NPS threaded fitting is compatible with Peerless-AV extension columns, including available fixed-length and adjustable models. This defined interface helps simplify component selection when the mounting system already uses Peerless-AV columns.

Cold-rolled steel construction provides the structural foundation for a maximum load capacity of 250 lb. The clamp is finished in black with powder-coated and fused-epoxy finishes, and it is specified as scratch resistant. These characteristics make it appropriate for exposed indoor mounting locations where both durability and a consistent black finish are important.

Installation and Integration

The clamp mounts to an overhead I-beam and provides the threaded fitting needed to connect a compatible mounting column. It is ceiling mountable and uses an adjustable mount function. Assembly is required, so the clamp should be incorporated into the planned installation process rather than treated as a preassembled mounting system.

The ACC559 weighs approximately 4.80 lb. Its listed device support includes mounting columns and ceiling mounts, while its stated application is I-beam mounting. The packaged quantity is one. Before installation, confirm the beam dimensions, total supported load, extension-column compatibility, and the requirements of the complete ceiling mount configuration.

A manufacturer specification sheet is available for detailed project reference. The supplied product data does not identify included tools or additional mounting components, so only the clamp itself should be assumed from the listed packaged quantity.

Performance Highlights

• Approximate product weight of 4.80 lb

What Makes It Different

Rather than serving as a general-purpose beam attachment, the ACC559 is designed around Peerless-AV ceiling-mount integration. Its threaded fitting provides a direct interface for compatible Peerless-AV extension columns, while the adjustable clamp configuration addresses overhead I-beam installations.

The model is UL Listed, TAA compliant, and compliant with the Restriction of Hazardous Substances requirements. Its country of origin is the United States. Together with the steel construction, 250 lb load rating, and scratch-resistant finish, these documented attributes provide clear criteria for evaluating the clamp against an installation specification.

Final Assessment

The Peerless-AV ACC559 is a focused indoor mounting component for connecting a compatible Peerless-AV ceiling system to an overhead I-beam. Its strongest considerations are the 250 lb maximum load capacity, cold-rolled steel construction, adjustable mounting function, and 1 1/2-11.5 NPS extension-column connection. For installations that match the documented beam dimensions and Peerless-AV column interface, it provides a clearly specified path from the structural beam to the ceiling mount.
