90 Degree Corner Bracket for 20 Series Aluminum Extrusion is a compact black anodized aluminum connector for compatible frame assemblies, enclosures, machine bases, fixtures, and custom hardware projects.
$2.95
The 90 degree corner bracket is a compact aluminum connector designed for joining compatible 20 Series aluminum extrusion at a right angle. Made from black anodized aluminum and sized at 20mm x 28mm x 28mm, this bracket is a practical hardware component for small frames, enclosures, machine builds, fixtures, guards, stands, and custom extrusion projects.
This 90 degree corner bracket is designed for compatible 20 Series aluminum extrusion systems. It helps create clean right-angle joints between extrusion profiles, making it useful for compact frame assemblies, equipment mounts, electronics enclosures, printer frames, light-duty machine structures, and modular hardware projects.
The current product page lists this bracket as black anodized aluminum. The black finish gives the bracket a clean appearance for visible frame assemblies while helping it match many common black extrusion systems and machine builds.
With a listed size of 20mm x 28mm x 28mm, this corner bracket is suited for smaller 20 Series extrusion assemblies where a compact 90 degree support is needed. Confirm extrusion series, slot size, bracket clearance, and required hardware before installation.
This bracket requires compatible 20 Series T-nuts, which are sold separately. Choose fasteners that match your extrusion slot, bracket holes, thread size, and assembly requirements.

Each 90 degree corner bracket is sold individually. Compatible 20 Series T-nuts and related mounting hardware are sold separately.
