About 105 x 105 x 90 mm Angle Bracket

The 105 x 105 x 90 mm Angle Bracket is a heavy-duty, L-shaped steel support bracket engineered to create strong, reliable 90-degree joints in a vast array of construction and DIY projects. Its specific dimensions—with two 105 mm arms and a 90 mm height—offer an optimal balance of substantial load-bearing surface area and structural depth, making it a versatile component for both visible and concealed reinforcement.

This angle bracket is constructed from thick, durable steel, often powder-coated or galvanized to resist rust and corrosion, ensuring long-term integrity in various environments. Featuring multiple pre-drilled holes on both arms, the 105 x 105 x 90 mm angle bracket allows for secure fastening with screws or bolts, distributing stress evenly and preventing joint failure. Whether you’re building a sturdy workbench, reinforcing a bookshelf, constructing a garden planter box, or adding stability to a deck railing, this bracket delivers professional-grade support with straightforward installation.

What Do the Dimensions 105 x 105 x 90 mm Represent?

Understanding the sizing is key to selecting the right bracket. For this 105 x 105 x 90 mm angle bracket, the first two numbers (105 x 105) refer to the length of each of the two perpendicular arms, measured from the inside corner outward. The third number (90 mm) indicates the height or the vertical depth of the bracket’s side profile.

This 90 mm height is a critical factor in the bracket’s strength, providing significant resistance against bending or twisting forces. A bracket with these dimensions offers a large mounting surface (105 mm) for solid attachment and a deep profile (90 mm) for formidable rigidity, making it suitable for medium to heavy-duty applications.

What is the Typical Weight Capacity of This Bracket?

Load capacity is a primary concern for users. While the exact weight limit depends on the wall material, fastener type, and load direction, a steel 105 x 105 x 90 mm angle bracket of standard thickness (e.g., 2-3 mm) can typically support a significant static load. As a conservative estimate for a properly installed bracket with two or more screws per arm into a solid substrate (like a wall stud or structural timber), it can often support 50 kg or more per bracket. For optimal safety in shelf applications, it is standard to use two brackets per shelf, effectively doubling the support. Always consider the weakest link in your assembly (the fasteners or the wall material) when planning your project with these angle brackets.

 How and Where Should I Install This Angle Bracket?

Installation questions are common for DIY projects. To install the 105 x 105 x 90 mm angle bracket, first, determine the precise 90-degree corner you need to reinforce. Hold the bracket in place so one arm is flush against each surface forming the corner.

Use a pencil to mark the positions of the pre-drilled holes. Pre-drill pilot holes in the marking to prevent wood splitting or to use appropriate wall anchors for masonry or drywall. Then, align the bracket and secure it using appropriate screws or bolts (usually not included) through each hole. This bracket is ideal for securing shelf standards to walls, reinforcing table legs to aprons, bracing gate frames, or strengthening the corners of wooden storage boxes.

What’s the Difference Between This and a Smaller Corner Brace?
Shoppers often compare brackets of different sizes. The 105 x 105 x 90 mm angle bracket is a substantial, heavy-duty option compared to smaller, flimsier corner braces. The larger arm length (105 mm) provides a wider distribution of force and more screw points for a stronger hold.

More importantly, the 90 mm height gives it exceptional vertical stiffness, preventing the “lean” or sag that can occur with low-profile brackets under load. While smaller braces are fine for lightweight picture frames or decorative joints, this 105 x 105 x 90 mm angle bracket is designed for structural applications where safety and long-term stability are paramount, such as supporting work surfaces or anchoring freestanding shelving units.

 Do I Need Special Fasteners, and Are They Included?
A practical question involves the necessary hardware. The 105 x 105 x 90 mm angle bracket typically comes with the bracket only; **fasteners (screws, bolts, wall plugs) are usually not included**. This is because the required fastener type varies dramatically based on the application—wood screws for timber, concrete anchors for masonry, or toggle bolts for drywall. You must select fasteners that are the correct diameter for the pre-drilled holes and of sufficient length to penetrate deeply into the supporting material. Using the correct, high-quality fasteners is just as important as the bracket itself to ensure a secure and safe installation.
