80/20 Inc. 40-4302 Inside Corner Bracket 40 Series

Product Description

The 80/20 INC. 40-4302 is a 2-hole inside corner bracket designed for structural framing applications using the 40 Series T-slot aluminum extrusion system. Machined from aluminum with a clear anodized finish, this bracket measures 36 inches in overall length and 6 millimeters in thickness. It forms a 90-degree connection between framing members and features a 2-degree drop-lock mechanism for secure, repeatable positioning. Licensed HVAC fabricators, industrial maintenance technicians, and structural assembly professionals use this bracket when building or modifying modular aluminum framing structures.

This bracket is intended for use in modular T-slot framing assemblies built on the 80/20 40 Series platform. It is suited for industrial workstations, machine guards, conveyor frames, enclosures, and similar structural builds where a rigid inside corner connection is required. Installation requires the companion 40 Series Bolt Kit 75-3422, which must be sourced separately. The bracket supports positioning along the extrusion length, allowing adjustment before final lockdown.
