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.
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.
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.
