Cabinet Triangular Support Black (3 sizes)

Our Cabinet Triangular Support is an excellent choice to reinforce the internal corners of cabinets, wardrobes, shelving units, and storage enclosures. Engineered for indoor applications, these right-angle steel brackets are ideal for securing wooden panels at 90° junctions, delivering enhanced structural stability in domestic and commercial furniture.

Each set includes two mirrored brackets (left and right), ensuring a symmetrical and secure installation across both sides of the cabinet corner. The brackets are manufactured from mild steel and finished with a durable black powder coating, offering both mechanical strength and corrosion resistance in indoor environments.

Key Features:

• Triangular bent steel design for optimal corner support
• Multiple precision-cut mounting holes to distribute load and enhance grip
• Countersunk and elongated holes allow for flexible screw alignment and ease of installation
• Smooth black finish blends discreetly with modern or industrial cabinetry
• Comes with necessary screws for installation (wood screws included)
