T-Slotted Framing Structural Brackets
Connect T-slotted rails and reinforce joints for structural stability. Fasteners are included.
For technical drawings and 3-D models, click on a part number.
Corner brackets are also known as angle brackets.
Extended brackets have more connection points for stronger connections than standard-length brackets.
Adjustable-angle brackets let you mount one rail to another at many different angles.
Concealed adjustable-angle brackets connect rails flush to each other at any angle.
Offset adjustable-angle brackets use a bracket placed between the rails to mount one rail next to another at any angle, including parallel to the connected rail.
Rotating end-mount adjustable-angle brackets create a 90° connection between two rails that lets one rail rotate around its connection point.
Surface adjustable-angle brackets come in pairs and let you mount one rail next to another at any angle but not parallel to each other.

Anchor concealed brackets allow positioning anywhere along the mating rail’s T-slot. Drill an installation hole in the face of one rail to install. Since the fastener is machined into the rail profile, these brackets create stronger connections than other brackets that don’t require machining. You can also use these brackets with our rails with machined bore holes.

Butt anchor concealed brackets join rails end-to-end to create longer rails. Drill an installation hole in the face of each rail to install. Since the fasteners are machined into the rail profile, these brackets create stronger connections than other brackets that don’t require machining.

Easy-adjust plate connector concealed brackets have fasteners that remain accessible after installation to simplify position changes. Often used to make shelf supports or cross bars to reinforce a structure, they create a structural bracket connection point on the end of one rail that can attach at a 90° angle along another rail. Install these brackets into the tapped end of a rail. Then, slide the spring-loaded ball nut into the slot on the other rail. Finally, fasten the outside bracket to the nut to connect the rails. You’ll get two brackets with all the included hardware.

Concealed anchors mount internally and stay out of sight once installed.
Miter butt anchors create the strongest miter connection because the fasteners are machined into the rail profiles. Use them to join rails with 60°, 90°, and 180° miters. Drill an installation hole in the face of each rail to install.
