FAQ
What is the difference between passage, privacy, and entry functions?
Passage (hall/closet) has no locking mechanism, the latch retracts from either side. Privacy (bedroom/bathroom) has a thumb-turn lock on the inside and an emergency release slot on the outside. Entry (exterior) has a key cylinder on the outside and a thumb-turn on the inside for full security.
Is SUS304 stainless steel significantly better than SUS201?
Yes, SUS304 contains 18% chromium and 8% nickel providing excellent corrosion resistance, especially in humid or coastal environments. SUS201 has lower nickel content and may develop surface rust in aggressive conditions. For exterior or high-humidity applications, SUS304 is strongly recommended.
Can the lever handles be installed on left and right opening doors?
Most LD-150 lever handle sets are reversible and can be installed on both left-hand and right-hand opening doors by simply reversing the latch orientation during installation. Confirm reversibility for your specific model variant.
What maintenance is required for stainless steel handles?
Clean periodically with mild soapy water and a soft cloth. Avoid abrasive cleaners or steel wool that can scratch the surface finish. For fingerprint resistance on satin finishes, a light wipe with mineral oil on a cloth restores the protective layer.
