The 90° corner L-plate is a black 30 Series aluminum extrusion connector designed for joining compatible extrusion profiles at a right angle. With a 90 mm × 90 mm size, 4 mm thickness, and 5-hole bracket design, this L-plate is a practical hardware component for frame assemblies, machine bases, enclosures, fixtures, guards, stands, and custom extrusion projects.
This 90° corner L-plate is designed for compatible 30 Series aluminum extrusion systems. It helps create strong right-angle connections between extrusion profiles, making it useful for square frames, support structures, equipment mounts, enclosure frames, and modular hardware assemblies.
The live product page lists this bracket with a black high-gloss powder coated finish. The black finish gives the bracket a clean appearance for visible frame assemblies, display structures, equipment builds, and custom projects where the hardware remains exposed.
The 5-hole layout provides multiple fastening points for compatible mounting hardware. This helps secure the bracket across the corner joint and supports a cleaner, more stable connection when the frame is properly aligned and tightened.
This 90° corner L-plate requires compatible M6 socket head cap screws and M6 T-nuts for installation. The required fasteners are sold separately, so confirm your extrusion slot, screw length, and T-nut style before ordering.

Each 90° corner L-plate is sold individually. M6 socket head cap screws and M6 T-nuts are required for installation and are sold separately.
