90 degree Brackets

Installation of 90 Degree Angle Brackets for Aluminum Profiles

90-degree angle brackets for aluminum profiles are corner connecting pieces (Brackets) used to join two aluminum profiles together at a 90° right angle, ensuring a strong and precisely perpendicular structure.

1. Position the angle bracket at the desired corner to be joined.
2. Use Nuts + T-Nuts or profile-specific locking bolts to fasten the angle bracket to the profile grooves.
3. Adjust the position to achieve a 90° angle and then tighten securely.

Usage Examples

• Securing table frames made from vertical + horizontal profiles.
• Assembling cabinets or machine frames with precise shapes.
• Creating load-bearing structures, such as conveyor belt frames.

Tools Used for Assembling - Removing 90 Degree Angle Brackets for Aluminum Profiles

• Hex wrenchs (Allen Key) or screwdriver according to the nut size.
• Wrenches / Offset Wrenches / Ratchet Wrenches (if using double-sided T-Nuts).
• Protective gloves (for safety).
• For large structures, a Electric Screwdrivers may be used to reduce effort.
• If disassembling multiple points, use component storage boxes to separate parts by location to prevent confusion.
• Apply a small amount of lubricants to stiff nuts or frequently used threads.

Selecting the Right 90 Degree Angle Brackets for Aluminum Profiles

• Profile Size Used: Check if you are using 20x20, 30x30, 40x40, 45x45, etc. profiles.
• Bracket Material: Cast aluminum (commonly used with aluminum profiles), coated steel (stronger, suitable for heavy loads).
• Number of Holes/Hole Pattern: Choose one that matches the profile holes, such as 2 holes, 3 holes, or slotted types.
• Thickness and Strength: For large structures, use thick brackets, e.g., 5 mm or more.
• Appearance: For a clean, sleek look, consider CNC machined or polished L-Brackets.

Additional Recommendations

For high precision: Use Brackets + L-Shape Connectors + Pin Locators for increased grip and no slippage.
For a clean and tidy look: Use internal or cover cap types.
