Inner bracket T6

Inner Bracket – 20 series T-slot 6 mm & V-slot 6 mm aluminium profiles, incl. set screws

The Inner Bracket is a practical and cost-effective way to connect 20 series T-slot 6 mm and V-slot 6 mm aluminium profiles quickly and neatly from the inside. Because the connector sits largely inside the profile grooves, it keeps the outside of your frame clean and free of protruding parts—ideal for compact machine frames, 3D printer and CNC frames, guards, workstations, prototypes, and general aluminium profile constructions where speed and simplicity matter.

Each inner bracket is supplied including set screws. Assembly is straightforward: position the connector in the profile, align the second profile, and tighten the set screws. As you tighten, the connector locks into place and fixes the profiles relative to each other—no complex machining or special tools required beyond a standard hex key.

How this connector performs

This type of internal connector is designed mainly to fix profiles in position. Unlike some heavy-duty joining methods, it does not strongly pull the profiles together during tightening. That means it’s not the strongest option for applications with high bending loads, heavy vibration, or where maximum joint rigidity is required.

That said, it’s an excellent solution when you want:

• A fast and economical connection method
• Simple installation with minimal effort
• A clean-looking joint with hardware mostly hidden
• Flexibility in design—because you can add more connectors if needed

For extra strength and improved stability, you can use multiple inner brackets per connection, depending on the load and the size of your construction. This makes it easy to scale up the joint strength without changing the overall design.
