No: 15 Flat Corner Brace 2.5x80x210 mm (50 Pieces)

No. 15 Flat Brace – 2.5 × 80 × 210 mm, Box of 50

No. 15 Flat Braces are extra‑long, extra‑wide heavy‑duty connecting plates engineered for the largest and most demanding connection requirements. With a 2.5 mm thickness, 80 mm width, and 210 mm overall length, they distribute load across an exceptionally broad surface and resist bending, warping, or distortion even under the most severe sustained loads. The flat profile suits main load‑bearing timber beam joints, large structural frames, and wide‑span systems built from thick materials. Supplied in boxes of 50, they provide stock efficiency for large‑scale construction and structural projects.

Applications

• Primary load‑bearing beams and post/column connections in timber structures
• Reinforcement for large‑framed doors, windows, and joinery systems
• Wide‑span joints in heavy timber, plywood, and engineered structural panels
• Custom heavy‑duty furniture and workbench manufacture
• Primary connection points for interior partition walls and support systems
• Repair of damaged or weakened major structural elements during renovation
• Prefabricated timber building and residential construction projects
• Commercial fit‑out and industrial fixture applications

Product Advantages

• 210 mm Extra‑Long Body: Roughly twice the length of standard braces; securely connects widely separated points, distributes load fully toward both ends, and completely eliminates stress concentration at the joint centre
• 80 mm Extra‑Wide Format: Enables six‑point fixing; provides an exceptionally broad grip area and reduces the risk of base material splitting or tearing to near zero
• 2.5 mm Robust Section: Stiffer and more resistant than standard 2 mm plates; permanent deformation does not develop under continuous heavy loading
• Six‑Point Security: Dual‑row fixing minimises rotation, slip, and gradual loosening; the connection remains rigid throughout its service life
• Zinc‑Plated Finish: Rust‑resistant indoors over many years; no discolouration, maintains a professional, clean appearance
• Simple Installation: No special tools required; fasten with correctly sized screws in seconds
• All‑in‑One Function: Performs as both connector and structural reinforcement in a single plate — no separate components needed
• Box of 50: Sufficient quantity for major projects; low unit cost delivers an economical long‑term solution

Installation Guidelines

• Ensure the mounting surface is flat, clean, and fully sound; uneven seating will impair load distribution
• Mark the joint location; centre the plate so it bears evenly across both mating members
• Select suitable fasteners: use wood screws with 5 mm head diameter; choose longer, thicker screws for dense or thick materials
• Tighten progressively in a crossing pattern; do not fully tighten until all screws are seated
• Avoid over‑tightening — threads may strip or the plate may distort
• Use additional plates for heavier loads; install symmetric parallel pairs rather than a single line
• Use stainless‑steel screws in damp locations such as kitchens and bathrooms
• Loosen screws gradually in a cross pattern during disassembly to avoid straining the base material

Frequently Asked Questions

How does this differ from other models?
Other wide plates measure 160 mm or shorter; No. 15 is the longest in the range at 210 mm. Its 80 mm width and six‑hole configuration deliver the highest load capacity of the series.

What weight can it support?
Its 2.5 mm thickness, 210 mm span, and six‑point fixing provide the highest capacity in its class. Suitable for reliable use even under sustained heavy loads when properly installed.

Will it rust?
Zinc plating provides adequate protection for indoor use. For exterior or persistently damp environments, the stainless‑steel version is recommended.

Are other sizes available?
Yes — options vary in thickness, width, and length. Select the dimensions that best match your application.

Are screws included?
No — plates only. Purchase fixings separately, matched to your material type and load requirements.
