Furniture leg Sourcing model 5-965.80.18(S) — black steel support for furniture (rectangular profile 800x300x40x5)

Sourcing furniture leg model 5-965.80.18(S) is a black steel support designed to stabilize and elevate a range of furniture types. Constructed from steel with a rectangular profile measuring 800x300x40x5 mm, this support provides a rigid and durable base for cabinets, worktops, shelving units and bespoke furniture. The minimalist black finish integrates into modern interiors while the substantial profile focuses on load-bearing performance and long-term stability.

Advantages

The steel construction and substantial rectangular profile deliver high rigidity and resistance to bending under load, making it suitable for heavy assemblies. The black finish offers corrosion resistance and a discreet visual presence, while the straightforward rectangular shape simplifies alignment and installation along furniture undersides or sides. Its dimensions give a wide contact area for secure attachment and improved distribution of weight.

Suitable for

• Kitchen and bathroom cabinets that require solid under-support.
• Worktops and countertops needing elevated, rigid supports.
• Shelving units and storage systems that demand stable legs with wide contact area.
• Custom furniture projects where a minimal, industrial look is desired.

When it may not be suitable

This steel support is relatively large and intended for applications where a prominent, heavy-duty leg is acceptable. It may not be suitable for very lightweight furniture or designs that require concealed or decorative legs. If a rounded or tapered aesthetic is required, the rectangular profile will not match those stylistic needs.

Key specifications

• Material: steel
• Finish: black coating
• Profile shape: rectangular
• Profile dimensions: 800 x 300 x 40 x 5 mm (length x width x depth x thickness)
• Intended use: furniture support and stabilization

How to use

Position the support under or alongside the furniture element to be reinforced, ensuring the long side aligns with the load-bearing direction. Mark and drill appropriate mounting points on both the furniture and the support, using fasteners suitable for the furniture material and the steel thickness. Tighten fixings evenly to avoid introducing stress points; verify level and stability once mounted. For best results, use multiple supports or additional bracing on wider spans to distribute load evenly.

What to consider before purchase

• Confirm the profile dimensions fit the furniture layout and available mounting space.
• Ensure the furniture material can accept mechanical fasteners compatible with steel supports.
• Verify the black finish and rectangular aesthetic match the intended design.
• Assess total expected load and whether one or multiple supports are required.

Usage recommendations

For durable results, use corrosion-resistant fasteners and, when installing in humid environments, consider additional protective coatings. Regularly inspect mounting points for loosening or wear and retighten as needed. Combine with complementary supports for long spans and heavier loads to maintain stability and prolong service life.
