AngleLock: A US Manufacturer of Aluminum Extrusion Frame Alternatives

AngleLock by Controlled Dynamics is a structural framing T-slot alternative that mechanically locks for ultimate precision. Not only that, this modular assembly is also as sturdy as steel framing – without the rusting.

We’re the only aluminum extrusion manufacturer in the USA with the patented, self-aligning technology that makes T-slot systems obsolete.
