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.
Radius, angled, and half-round rails give a finished appearance. They are often used to create finished edges or handles on carts.
Double-, triple-, and quad-profile rails are good for large structural applications, such as beams and posts. Typically, the larger the rail profile, the stronger the rail.
Solid rails are stronger than hollow rails. Hollow rails are lighter and more economical than solid rails.
Grooved rails help you align rails when connecting them. They also camouflage dents and marks better than smooth rails but can collect dust and grime. 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.
Rails with tapped, access, and bore holes come already machined, so they're ready to be used with concealed structural brackets to make 90° connections between rails.
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.

For rails with bore holes, the bracket can be loosened, moved along the rail, and retightened without drilling a new hole like you need to do with rails with access holes. You can use them with anchor concealed brackets.
Those machined on one end are best for making tabletops. If you need to shorten the length of the rail, you can cut down the opposite end. Those machined on both ends are good for making boxes and enclosures.
