BEST 40HTKIS115H626 – Frequently Asked Questions

1) Does the BEST 40H inside lever trim kit include the mortise lock body?
No. The 40H inside lever kit is trim only, the lever, spindle side and rose for the inside face of the door. There is no mortise case, latch or keyed cylinder in it, and it is non-keyed. You order it to go onto a compatible BEST 40H Series mortise lock chassis that is already in the door, or alongside a new 40H lock body.
2) Will BEST 40H mortise trim work on a 2-3/4 inch backset door prep?
That is exactly what it is built for. The kit is a 2-3/4 inch backset configuration, which is the standard commercial mortise prep, so it lines up with a door already mortised for a 40H lock. It will not adapt to a 2-3/8 inch bored-lock prep.
3) Do I need to specify handing when ordering BEST 40H inside lever trim?
No handing to call out. The 40H trim kit is non-handed, so the same part goes on a left or right hand door. That is useful if you stock spares for a building with mixed swings, since one part number covers every opening.
4) What do I have to specify to order a BEST 40H lever trim kit?
Three choices. Lever style: 12 solid tube with no return, 14 curved with return, 15 contour with angle return, 16 curved without return, 3 solid tube with return, or 4 round knob. Trim style: H flat 2-3/4 inch rose, R concave 2-3/4 inch rose, or S flat 3-1/2 inch rose. Then finish, from 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil-rubbed satin bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, or 630 satin stainless.
5) Is BEST 40H trim rated for high traffic commercial doors?
Yes. The 40H trim is certified to ANSI A156.13, Series 1000, Grade 1 operation, which is the top commercial mortise lock grade, and it is built on a steel frame rated heavy duty for commercial use. That is the level facilities standardize on for schools, hospitals, and government buildings.
6) I need the inside lever trim to match the other doors in my building. How do I match an existing BEST 40H opening?
Match on three things: the lever design, the rose, and the finish. Pull one existing lever off and compare it against the 40H lever options (12, 14, 15, 16, 3, or the 4 round knob) and the rose shape, either a 2-3/4 inch flat rose (H), a 2-3/4 inch concave rose (R), or a 3-1/2 inch flat rose (S). The 3-1/2 inch S rose covers a bigger footprint, which helps if the door face is marked around an older trim. Finish codes are stamped standards, so 626 satin chrome on the existing doors is 626 here.
7) Can I use this BEST 40H trim on an access control or electrified opening?
Not as an electrified component. This is a mechanical, non-electronic lever trim with no wiring, no request-to-exit switch and no cylinder. It can sit on the inside face of an opening that is controlled elsewhere, but the trim itself does nothing electrically.
8) Can I order a round knob instead of a lever on the BEST 40H inside trim?
Yes, style 4 is a round knob rather than a lever. Be aware that knobs are generally not acceptable where accessible-route hardware is required, since a lever is the usual choice on those openings. If the door falls under accessibility requirements, pick one of the lever designs (12, 14, 15, 16 or 3).
9) Where can I find the full BEST 40H mortise lock specs and function codes?
BEST publishes a 40H Series Heavy Duty Mortise Locks catalog covering the series functions, trim and lock body details. ZenSupply hosts it at https://zensupply.com/content/pdf/best/BA-0012_BEST_40H-Catalog-06-23.pdf. Worth pulling before you order if you are matching trim to an existing lock function.
