Square Adjustable Aluminium Furniture Legs & Cabinet Leveling Feet (BLS-AL38)
Adjustable aluminium furniture legs are corrosion-proof square metal support columns featuring a threaded base pad designed to level and elevate cabinetry, tables, and upholstery on uneven floors. Manufactured by BLS Hardware in Jinli, Guangdong using structural 6063-T5 extruded aluminum alloy with thick mounting flanges, the BLS-AL38 series provides exceptional waterproof performance, high compression load capacity, and sleek architectural lines for residential and commercial furniture makers.
Key Features & Engineering Benefits
- Precision Threaded Height Adjustment (0–15mm): Features a heavy-duty polymer bottom screw base that smoothly rotates to level cabinets and sectionals on uneven tile, stone, or hardwood flooring.
- 100% Waterproof & Rust-Proof Aluminum: Extruded from structural 6063-T5 aluminum alloy, making these legs completely immune to rust, moisture, and chemical floor cleaners in high-humidity kitchen and hospitality environments.
- Heavy Contract Compressive Load Rating: Thick-walled square extrusion profile and reinforced internal screw bosses support up to 1,760+ lbs (800 kg) static vertical load per set of 4 legs.
- Dual Top Mounting Flange Options: Available with centered square flat plates or integrated 90° corner gusset brackets to brace wooden carcass framing directly.
- Architectural Anodized Finishes: Multi-stage anodized matte black and brushed satin silver finishes resist scratching, peeling, and oxidation over decades of daily use.
- Anti-Scratch Base Glide: Heavy-duty wear-resistant ABS polymer foot base prevents floor scuffing and dampens dragging vibrations.

Frequently Asked Questions (FAQ)
Q1: What is the recommended maximum extension height for optimal stability?
A: While the internal threaded base can extend up to 15 mm, we recommend adjusting between 5 mm to 10 mm for heavy modular sofas, kitchen islands, and wardrobe installations to maintain maximum structural rigidity and lateral load resistance.
Q2: Can we order different top mounting plates (centered square vs offset corner)?
A: Yes. Both flat square center plates (for middle support) and offset 90-degree triangular corner mounting flanges (for direct carcass frame corner bracing) are available for the BLS-AL38 series and can be customized to your screw hole spacing.
Q3: What is the MOQ and sample lead time for wholesale orders?
A: Standard production MOQ is 500 pcs. Free evaluation sample packs with different heights and finishes are dispatched within 1–2 business days for factory engineering testing.
