80/20 Inc. 25-4113 Inside Corner Bracket 25 Series

Product Description

The 80/20 INC. 25-4113 is a 4-hole inside corner bracket designed for use with 25 Series T-slot aluminum framing systems. Made from aluminum with a clear anodized finish, it creates rigid 90-degree inside corner connections within modular structural assemblies. The bracket features a 2-degree drop-lock geometry that locks components into position during assembly, simplifying alignment before final fastening. At 47 inches in overall length, it spans extended corner joints in larger frame builds. This bracket requires the 75-3404 bolt kit for proper installation and is intended for use by fabricators, machine builders, and industrial maintenance professionals working with T-slot framing.

The 25-4113 is suited for modular workstations, machine guards, enclosures, and structural frames built on the 80/20 25 Series platform. Its inside corner profile allows it to sit flush within frame assemblies where external brackets would interfere with panels or adjacent components. The clear anodized aluminum finish provides corrosion resistance for light industrial environments. This bracket is appropriate for both new builds and retrofit or expansion projects using existing 25 Series extrusion.
