T-Slotted Framing Structural Brackets

Connect T-slotted rails and reinforce joints for structural stability. Fasteners are included.

Corner Brackets for Double and Quad Rails

Corner

Extended Corner

Extended Open Gusset

Extended Closed Gusset

Corner brackets are also known as angle brackets.

Extended brackets have more connection points for stronger connections than standard-length brackets.

Gusset brackets are reinforced to limit sway for more structural stability than standard corner brackets. Open gusset brackets give you easy access to the fasteners, which is useful if your application requires frequent adjustments. Closed gusset brackets include a cover for a finished appearance and better dust protection than open gusset brackets.

Surface Brackets for Double and Quad Rails

Straight

90° Angle

Tee

Surface brackets create strong connection points because they secure to the surface of rails.

Straight brackets are simple brackets that can be used to make 90°, end-to-end, and parallel connections.

Extended brackets have more connection points for stronger connections than standard-length brackets.

90° angle brackets make a corner or create another 90° connection along your rail.

Diagonal Brace Ends for Double and Quad Rails

Use diagonal brace ends to make a brace of any length—a connecting rail (sold separately) between the brace ends is required. To install, use a tap (sold separately) to create a threaded hole, then fasten the brace end to a connecting rail using the included hardware. Brace ends with no required tap thread size include thread-forming screws.

Anchor Concealed Brackets

Concealed brackets mount internally and stay out of sight once installed.

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

Concealed brackets mount internally and stay out of sight once installed.

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-Install Tabbed Concealed Brackets

Concealed brackets mount internally and stay out of sight once installed.

Easy-install tabbed concealed brackets come with a self-tapping screw, so you won't need to tap the end of your rail or drill an acess hole to make 90° and corner connections. Position them anywhere along the length of your rail. Their connections are stronger than corner concealed brackets and tabbed concealed brackets but not quite as strong as anchor brackets.

Plate Connector Concealed Brackets

Concealed brackets mount internally and stay out of sight once installed.

Plate connector concealed brackets create a structural bracket connection point on the end of one rail that can attach at a 90° angle along another rail. They have a screw on one side and a T-slot nut on the other. Tap a hole in the end of one rail and thread in the screw. Then slide the T-slot nut into the slot of the other rail. Brackets with no required tap thread size include thread-forming screws.

Miter Anchors

Concealed anchors mount internally and stay out of sight once installed.

Miter anchors connect rails with 30°-90° miters. Drill an access hole in each rail and slide the connector into the center hole, then thread the set screws into the T-nuts, through the access holes, and into the connector.

Butt Connectors

Extended Butt Connector

Concealed connectors mount internally and stay out of sight once installed.

Butt and extended butt connectors join rails end-to-end to extend the length of rails without machining. Slide the connectors into a T-slot and tighten the screws to install.
