Marks USA 110LC-32D Satin Stainless Steel Door Lock

Satin Stainless Steel Privacy Lock

The Marks USA 110LC-32D is a cylindrical knob lockset finished in satin and polished stainless steel. It carries a BHMA certified ANSI-A 156.2 Grade 2 rating and a three-hour fire rating. The lock is designed for privacy use on bedroom and bathroom doors. It ships keyed different in a single box.

Grade 2 cylindrical standard limits

The ANSI-A 156.2 Grade 2 certification sets the baseline for residential heavy-duty performance. It covers latch strength, cycle endurance and operational torque but does not extend to commercial high-traffic requirements. The 1/2" throw latch and 1" x 2-1/4" front are built to this standard. UL listing confirms compliance with the three-hour fire door assembly test.

Fits 1-5/8" to 1-7/8" thick doors

Adjustable roses on both sides accommodate the stated door-thickness range. The 2-3/4" diameter roses and matching 2-3/4" "T" strike align with common residential prep. Doors thinner or thicker than the specified range fall outside the adjustment capability. Buyers needing a passage, entry or classroom function should select a different lockset.
