90° Triangle Aluminum Connectors for T-Slot Profiles
These reinforced 90-degree triangle connectors create rigid right-angle joints in modular T-slot aluminum profile frames. The wide mounting faces and triangular ribs help distribute load across both profiles, making the brackets suitable for worktables, machine frames, guards, racks and automation structures.

Key Benefits
- Creates a rigid 90-degree joint between two aluminum profiles.
- Triangular ribs improve resistance to flexing and rotation.
- External mounting makes installation and inspection straightforward.
- Silver and black finishes coordinate with common extrusion systems.
- Multiple sizes support light, medium and heavy modular frames.
Product Details



Installation
- Position the two profiles at a true 90-degree angle.
- Place the connector against both external profile faces.
- Align the bracket holes with compatible T-nuts in each slot.
- Install the matching bolts and tighten both sides gradually.
- Verify frame squareness and retighten to the required torque.
How to Choose the Correct Connector
Match the connector series to the profile width and verify the hole diameter, hole spacing, bracket height and mounting-face width. For load-bearing structures, consider the joint direction, applied moment and number of brackets. Provide an extrusion cross-section drawing when compatibility is uncertain.
Applications
Common uses include industrial worktables, machine frames, safety enclosures, conveyor supports, display structures, storage racks, robotics cells, laboratory furniture and modular equipment bases.
Frequently Asked Questions
Will one bracket fit every profile of the same nominal size?
No. Slot position, groove width and external geometry can vary. Please confirm the profile cross-section and fastener size.
Are black connectors available?
Yes. The product is shown in silver and black finishes. Availability depends on connector size and order quantity.
Can the hole pattern or dimensions be customized?
Yes. Custom dimensions, hole patterns and finishes can be reviewed from drawings for volume orders.
