Aluminum Beam Extrusion, Double-Side Ditch, 1.57" x 10 ft

The 4-H4-10 is an aluminum beam extrusion with a double-side ditch profile, supplied in a 10 ft length with a cross-section of 1.57 in wide by approximately 1.57 in tall (40 mm x 40 mm nominal). It is designed for use in modular exhibition display systems, interior signage structures, and commercial display frameworks where repeatable component alignment and secure fabric or panel retention are required. The extrusion is constructed from aluminum, providing a corrosion-resistant, lightweight structural member suited for both permanent installations and reconfigurable display builds. The dual-side ditch channels allow hammerhead screws and compatible connectors to be inserted and repositioned along the full length of the beam without drilling. Catalog weight is listed at 0.28 kg/m. No certifications are confirmed in the available source documentation for this product.
