Trimco 81ST002-Tubular Locks (Frankfurt)

Yes. The Frankfurt lever from Trimco's Urban series is built to a 2-3/8 inch backset, which is the shallower of the two standard tubular backsets and the one most common on interior and residential-style openings. If your existing bore is centered 2-3/4 inches from the door edge, this is the wrong backset and the lever will not line up with the cross-bore.

Four functions are offered and they are not interchangeable. Passage is a latching lever with no lock, for corridor and closet doors that just need to stay shut. Privacy locks from the inside, for bathrooms and bedrooms. Full dummy is a fixed lever with no latch at all, mounted on both faces of an inactive leaf or a closet door that is held by a magnet or ball catch. Half dummy is a single fixed lever for one face only, and it is handed, so the left hand half dummy is what you order for a left hand door.

Only for the half dummy. The half dummy is offered as a left hand unit, so handing has to be established before you order it. The passage, privacy and full dummy functions are not handed on this lever.

It is ADA compliant, which is the point of the lever shape: no tight grasping or wrist twist to operate. Trimco lists the Urban series levers as meeting ADA, and the Frankfurt is specified as commercial-grade trim rather than residential. That is the combination an institutional or MRO buyer needs for public-side doors in offices, government and military facilities, hospitality and multifamily.

No. The Frankfurt is offered in passage, privacy, full dummy and half dummy only, so none of the four functions takes a key or a cylinder. For a keyed opening you need a different function entirely, or a separate deadbolt alongside a passage lever.

The Frankfurt lever measures 5-3/8 inches in lever length. That is the number to work from when you are checking clearance to a return wall, a frame stop, or hardware on the neighbouring leaf of a pair. Lay 5-3/8 inches off the rose and confirm the lever tip has somewhere to travel before you commit on a tight jamb condition.

Stainless steel construction, and Trimco positions the Urban series specifically at high-rise condo and multifamily work along with commercial and industrial buildings, offices and hospitality. Stainless is the material property managers standardize on for fleets of doors because it takes cleaning and handling without the finish going soft.

Yes, and that is the usual way to keep an opening looking consistent. Order passage or privacy where the door has to latch, then the full dummy for both faces of a non-latching leaf and the half dummy where only one face is visible. Same Frankfurt lever, same 5-3/8 inch lever length across all four functions, so the trim reads identically down a corridor.

Some are not. Trimco lists finishes 499, 609, 610, 611, 612, 613, 616, 619, 620 and 622 as non-returnable. Those are the ones to confirm against your finish schedule before release, because a mismatch on any of them stays with you.

For quantities above 10 pieces, Trimco asks that a quote be requested before the order is placed rather than ordering straight through. Plan that into the schedule on a fleet rollout, and get the function split (passage, privacy, dummies) settled before the quote goes in so the release matches the door schedule.
