Marks USA K22/3 – Frequently Asked Questions

1) What is the Marks USA K22 knob and rose kit, and does it include the lock body?
The K22 is a knob and rose kit only, covering both the exterior and interior sides of the door. It is the trim, not the lock. It goes onto the Marks Ornamental Iron Mortise Lockset 22AC/3, so the mortise lock case itself has to be there already or ordered separately.
2) Will the Marks K22 knob kit fit a 1-3/8 inch door?
Yes. The K22 covers door thicknesses from 1 inch through 1-3/4 inches, so 1-3/8 inch (the common older interior thickness) and 1-3/4 inch (standard commercial) both fall inside the range. Thin ornamental iron and glass-front stile doors down to 1 inch are covered too, which is where a standard cylindrical trim usually runs out of spindle.
3) Can I use the K22 knob and rose kit on a mortise lock other than the Marks 22AC/3?
No. The K22 is built for the Marks Ornamental Iron Mortise Lockset 22AC/3. The hub, spindle and rose pattern are matched to that case, so treat it as 22AC/3 trim rather than a general mortise trim. If you are replacing knobs on a different mortise lock, match the trim to that lock's own series.
4) What do I have to specify when ordering the Marks K22 kit?
Two choices. Pick the model, K22/3, and pick the keying: KD keyed different, KA keyed alike, or None for a less-core setup where you are supplying or reusing the cylinder. Keyed alike is the one property managers want when several iron gates or entry doors on the same site should run on one key.
5) My ornamental iron door has a Marks mortise lock but the knobs are worn out. Do I need a whole new lockset?
Not if the case is a 22AC/3 and still working. The K22 replaces the knobs and roses on both faces and leaves the mortise case in the door, which means no new mortise pocket, no new face prep, and no strike work. Order it less core if you are keeping the existing cylinder, or keyed alike if you want the rest of the property brought onto one key at the same time.
6) Is the Marks K22 knob durable enough for a high-traffic commercial entry?
The hub is iron, and the kit is specified as commercial rather than residential. Iron hubs are what takes the load on a knob trim, so this is the part of the assembly that normally fails first on an abused door. It is the right class of trim for office, retail, school, healthcare and multi-tenant entries.
7) What finishes does the Marks K22 ornamental iron knob kit come in?
Bright brass and satin chrome. Two choices, so match whichever is already running on the adjacent gates or entry doors. Bright brass suits older ornamental ironwork; satin chrome reads closer to contemporary commercial trim.
