40mm Adjustable Aluminum Furniture Legs (BLS 40mm Series)
The 40mm adjustable aluminum furniture legs manufactured and supplied by BLS Hardware are extruded metal support feet featuring a heavy-duty threaded base mechanism designed for precision height leveling and elevation. BLS Hardware supplies these 40mm square aluminum feet directly to furniture manufacturers, OEM brands, wholesalers, and hardware distributors for use on sofas, modular sectionals, storage credenzas, and commercial casework.
Fabricated at our precision extrusion facility in Jinli Town, Gaoyao District, Guangdong (Zhaoqing Gaoyao Jinli Zhengkai Hardware Factory), these 40mm adjustable aluminum furniture legs utilize 6063-T5 aluminum alloy to maintain structural rigidity without adding excess deadweight to furniture carcasses. The bottom glide incorporates an internal threaded stud that rotates smoothly, enabling installers to adjust overall elevation from 0 to 15 mm to correct for uneven subfloors while protecting hardwood and tile surfaces from marring.
Key Features of 40mm Adjustable Aluminum Furniture Legs
- Extruded 6063 Aluminum Profile: Standard 40mm cross-section with 1.0mm–1.2mm thickened walls, engineered for solid vertical support across upholstery and commercial casework plinths.
- 0–15mm Threaded Height Leveling: Rotatable dense polymer base glide allows precision on-site adjustment to eliminate furniture rocking and uneven joint seams.
- 100% Rust-Proof Material Performance: Naturally corrosion-resistant aluminum alloy prevents moisture damage and floor rust staining, making these feet ideal for high-humidity areas, kitchen plinths, and bathroom vanities.
- Pre-Drilled Top Mounting Flange: Stamped metal top plate with pre-drilled countersunk holes facilitates rapid attachment using standard wood screws or machine bolts.
- Architectural Surface Treatments: Available in anodized matte black, satin silver (10-15μm), brushed metal, and titanium gold to complement diverse furniture hardware suites.
- Robot Vacuum Clearance (150mm Options): Standard 150mm elevations provide generous clearance for robotic vacuum cleaners (Roomba, Roborock) to navigate freely beneath furniture.

Frequently Asked Questions (FAQ)
Why are 40mm adjustable aluminum furniture legs ideal for bathroom vanities?
Extruded 6063 aluminum alloy is naturally rustproof and impervious to moisture, making these legs ideal for high-humidity environments like bathrooms and laundry rooms where carbon steel legs might corrode over time.
How much vertical leveling adjustment do these aluminum legs offer?
The integrated concealed leveling base provides continuous threaded height adjustment from 0 to 15mm, allowing millwork installers to compensate for sloped or uneven tiled floors.
Can BLS Hardware manufacture custom lengths and anodized colors?
Yes. As a direct source factory in Jinli, Guangdong, BLS Hardware can extrude custom profile lengths from 60mm to 300mm and supply anodized finishes including satin silver, brushed black, and champagne gold.
