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.
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.

Heavy Duty Locking-Slotted Framing and Fittings

Build structures that stand up to more vibration and movement than T-slotted framing but with the same versatility and installation ease. Instead of T-shaped slots, these rails have slots that turn up and inward to keep connections rigidly locked together. Use them to make strong and stable platforms, machine bases, and much more.
These rails are not compatible with components designed to fit in T-slots.

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.

Enclosed Push-Button Switches for T-Slotted Framing
![]() | ![]() 4-Pole Micro M12 Plug |
![]() 8-Pole Micro M12 Plug |
Snap these switches onto your T-slotted framing rails—no need to drill or disassemble your existing structure. All come with a mounting bracket that fastens directly onto the rail with the included drop-in fasteners. Their built-in clip hooks onto the bracket, so there’s no need to open the housing to mount them. You can adjust their position by sliding them down the rails. With a push button, they’re quick and easy to actuate.
Switches with IO Link connect to a programmable logic controller (PLC), so you can remotely view outputs and receive error messages from your PC. Often used in production lines, they can let maintenance teams know about problems with equipment before they physically check it.

Clip these switches onto nearby structures made from T-slotted framing to quickly cut power with the push of a button. These switches meet EN 60947-5-1 and EN 60947-5-5, so they comply with European safety standards for reliably stopping machines.
You don’t need to take apart your existing structure or open the switch’s plastic housing to mount them. Fasten the included bracket to a rail with the included drop-in fasteners, then clip the switch onto the bracket.
Switches with two buttons have one button for an emergency stop and another button that can be wired to any equipment nearby.
