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.
