Arrow AM13 TA 3 Apartment, Front Door Mortise Lock, T Knob, A Rose

The AM13 is the apartment/front door function: a single cylinder mortise lock with a deadbolt. The outside knob is locked or unlocked by the key, and the deadbolt is thrown and retracted by the inside turnpiece. Inside knob is always free for egress. It is the standard setup for apartment entry doors and unit front doors where the tenant wants a separate deadbolt throw from the inside.

No. The AM13 is built for 1-3/4 inch doors, which is the standard commercial thickness. A 1-3/8 inch door, common on older interior openings, is too thin for this lock case and trim. You would need a different lock for that opening.

Backset is 2-3/4 inches, and the lock case measures 5-7/8 x 4 x 15/16 inches, with an 8 x 1-1/4 inch armored front. Arrow uses one standardized case size across the AM Series, so if the existing pocket was cut for an AM or BM Series mortise lock the AM13 drops straight in. On a pocket cut for another manufacturer, measure the pocket depth and the face cutout against those numbers before you commit.

Order it as-is. The AM13 is handed but field reversible, and the hand can be changed without opening the lock case. That matters on a multi-unit job where you are stocking one lock for both left and right hand doors.

Depends on the strike prep. The latchbolt has a 3/4 inch throw and the deadbolt throws 1 inch, so the strike needs cavities deep enough for both. Arrow ships an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your frame is cut for a standard ANSI 4-7/8 inch strike, it will take it. Optional strikes, other lip lengths and an ANSI wrought strike box are available if the frame is beveled or the jamb is deeper than standard.

Yes. The AM Series supports master keying, construction master keying, visual key control and concealed key control, and it accepts interchangeable core in Arrow's Pointe, Choice Base, Plus and Flex formats. Two nickel silver keys come standard. For a property manager standardizing a building, specify the keying system with the order rather than trying to sort it at the door.

They are the trim designations. T is the knob design and A is the rose design, so AM13 TA is the AM13 lock with a T knob on an A rose rather than a lever or an escutcheon plate. If the rest of the building is on levers, you would want a lever trim designation instead so the openings match.

It is a commercial mortise lock, intended for heavy duty use in schools, hospitals and commercial buildings. The case is heavy gauge steel with a zinc dichromate finish for corrosion resistance, the armored front is heavy gauge steel, and both the latchbolt and deadbolt are stainless steel. The latchbolt is a two-piece mechanical design with an anti-friction insert, and there is an auxiliary deadlocking latch with 9/16 inch effective throw and 3/8 inch deadlocking.

Center to center from the hub to the cylinder is 3-5/8 inches, and hub to turnpiece is 2-7/16 inches. The armored front accommodates flat doors and doors beveled 1/8 inch in 2 inches. Rose trim on the AM Series is self aligning, which takes the bind out of the trim during install.

The AM13 puts the latch and the deadbolt in one mortise case, so you cut one pocket and prep one opening instead of boring a lockset plus a separate deadbolt above it. The tradeoff is that the door has to be mortised, which means a heavier prep and a 1-3/4 inch door. If your doors are already bored for cylindrical hardware and you do not want to re-prep, two-piece cylindrical plus deadbolt stays the easier route. For new apartment entries specified commercial, the single mortise case is the cleaner job.

Bright brass, 605. That is the finish across the AM13 TA offering, so if you are matching existing hardware in a lobby or corridor on 605, it lines up. Faceplate and strike are wrought brass, bronze or stainless steel depending on the finish supplied.
