Door Lock Connection Accessories

What Sets Our Door Lock Connection Accessories Apart

• Material mastery

– Investment-cast 304 or 316 stainless steel for coastal or high-humidity projects.

– Low-carbon steel options for cost-effective indoor use.

– Optional zinc-alloy casting bodies when weight reduction is critical.

• Micro-machined tolerances

Modern Mazak 5-axis centers hold ±0.02 mm on lever spindles and cam profiles, eliminating wobble and extending lock life beyond 200,000 cycles.

•  Corrosion-proof surface

Automated electro-polishing plus 48-hour salt-spray zinc-nickel plating passes 1,000-hour neutral salt-spray tests without red rust.

• Rapid customization

3D-printed wax patterns allow us to modify hub lengths, spline counts or thread pitches in 7 days-perfect for OEM smart-lock retrofits.
