T-Slotted Framing Rails
Use this versatile framing to configure machine guards, enclosures, carts, and workstations. These rails have continuous T-slots for attaching fittings. When choosing how many slots you want on your rail, consider how much flexibility you need for your setup and how finished you'd like your structure to appear. The more slots the rail has, the more design flexibility you will have. Keep in mind, open slots can collect dust and debris. Rails with closed sides give you a finished appearance but are more difficult to reconfigure or add components to later. All of these rails are made of aluminum.
Low-profile rails are half the width of double rails. They’re often used to attach handles, sensors, and other accessories.
Solid rails are stronger than hollow rails. Smooth rails give a finished look. With no indentations to collect dust, they’re easier to clean than grooved rails. However, dents and marks are easier to see.
Black rails fade into the background and hide dirt and grime. They're good for vision systems where non-reflective material is needed. Yellow rails draw attention and are often used to build machine guards.
Cut-to-length rails can be ordered in increments of 0.125” or 0.25 cm.

T-Slotted Framing Structural Brackets
Connect T-slotted rails and reinforce joints for structural stability. Fasteners are included.

Corner brackets are also known as angle brackets.
Extended brackets have more connection points for stronger connections than standard-length brackets.
Countersunk brackets have a more finished appearance than brackets with straight mounting holes because their fasteners sit flush with the brackets. The screw heads won’t get in the way of your other components.
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 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.
Countersunk straight brackets have a more finished appearance than brackets with straight mounting holes because their fasteners sit flush with the brackets. The screw heads won’t get in the way of your other components.
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.
Flush tee and flush 90° angle brackets create a finished appearance. However, they are not as strong as standard tee or 90° angle brackets.

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. 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.
