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.

Tabbed concealed brackets require one hole to install the connector and one drilled access hole in the mating rail to secure the connection. You can also use these brackets with our machined rails with tapped or access holes. The brackets with a required tap thread size create stronger connections than other brackets that don't have tapped holes because the fasteners are machined into the rail profile. Brackets without a required tap thread size include thread-forming screws so you won't need to tap the end of your rail to install the connector. However, this connection is not as strong as the connections with a tapped hole.

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 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.
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.

Lightweight Composite T-Slotted Framing and Fittings
Build lightweight structures, such as light duty machine guards, enclosures, and carts, with framing that is two-thirds the weight of aluminum framing. Made of 30% polypropylene and 70% wood, they’re not as strong as aluminum rails, but they’re nonconductive, easy to machine, and more corrosion resistant. Good for lab environments, they also withstand cleaning with chemicals better than aluminum. Use their continuous T-slots to attach fittings. They work with any T-slotted component for 40 mm rails that doesn’t require machining. View additional structural brackets and fasteners.
Brackets connect T-slotted composite rails for structural stability. Fasteners are included.

Concealed brackets mount inside rails, so they stay out of the way and out of sight once installed.
Tabbed brackets mount inside a hole in one rail and require a drilled access hole in the mating rail to secure the connection. They come with thread-forming screws, so you don't need to tap the end of your rail.
