BEST 45HCAT626 – Frequently Asked Questions

1) What does the dormitory function on a BEST 45HCA mortise lock actually do at the door?
Dormitory function means the outside lever is locked or unlocked by key, and the four position hub toggle inside the case sets how it behaves: always locked, always unlocked, or locked by key. It's a single cylinder lock, so keying is on one side only. That's why it lands in student housing, apartments, hotel guest rooms and patient rooms, where a resident wants to leave the unit secure but staff needs key access. If you need a lever that relocks automatically every time the door closes regardless of the toggle position, dormitory is not that function.
2) Will the BEST 45HCA mortise lock body fit a door thicker than 1-3/4 inches?
Standard configuration is built for 1-3/4 inch doors, which is the usual commercial thickness. For anything thicker, up to 5 inches, BEST builds a thick door configuration and you have to state the actual door thickness when you order. It is not a field adjustment you make on a standard body, so measure the leaf before the order goes in.
3) Do I have to order the BEST 45HCA lock body handed, or can I flip it on site?
You do specify handing on the order (right hand, left hand, right hand reverse bevel, or left hand reverse bevel), but the latch is field reversible: it rotates 180 degrees to change handing without opening the case. The auxiliary bolt is non-handed. So if a door gets rehung or a shipment shows up handed the wrong way, a locksmith can correct it at the opening rather than sending it back.
4) Does the BEST 45HCA come with a cylinder or core?
No core is included. The body is prepped for a BEST small format interchangeable core and ships less core, so you supply the core in your own keyway and keying. That's how it gets folded into an existing SFIC master key system, but it also means an order with only the lock body will not operate until a core is on site.
5) Is the BEST 45HCA lock body the complete lockset, or do I still need trim?
Lock body only. It's the mortise case with the latch, deadbolt and armored front, plus the faceplate, and it needs levers or knobs and escutcheon or sectional trim ordered separately, along with the core and a strike. Two order add-ons sit with the body itself: security head screws, and a strike with 7/8 inch lip to center if your frame needs that lip dimension.
6) Will the BEST 45HCA latch and deadbolt engage my existing mortise strike?
Throws are 3/4 inch on the latchbolt and 1 inch on the deadbolt, both stainless steel. Against a standard ANSI mortise strike and frame prep at a 2-3/4 inch backset those engage normally. Where it gets tight is deep-set or shallow-lip frames: if the strike lip to center measurement on your frame is 7/8 inch, order the lock with that strike option rather than trying to shim the existing one.
7) Is the BEST 45H series Grade 1, and does it meet Grade 1 security?
The 45H carries ANSI A156.13 Series 1000, Grade 1 Operation and Strength, with Grade 2 Security as supplied. Grade 1 Security is reachable but conditional: with escutcheon trim you need a drill resistant core (1CD, 1CDP, 1CDF or 1CDX), and with sectional trim you need the 1EK7K4 high security cylinder. If your spec calls for Grade 1 across operation, strength and security without those cylinder conditions, the 47H series is the one written that way. The 45H design also meets the intent of ANSI A117.1 section 404.2.6.
8) Which finish should I order for a hospital or care facility corridor?
BEST offers two antimicrobial options on the 45HCA: 626AM satin chrome and 630AM satin stainless steel, both with the UltraShield coating that inhibits growth of bacteria and other microbes on the hardware surface. BEST recommends it wherever cleanliness is a priority, which covers healthcare, elderly care, education, transportation, food service and hospitality. On everything else the finish is cosmetic, so match what's already on the other openings.
9) What finishes does the BEST 45HCA mortise lock body come in, and which ones change appearance over time?
Fifteen finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil rubbed satin bronze, 618 bright nickel, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 626AM antimicrobial satin chrome, 629 bright stainless, 630 satin stainless, 630AM antimicrobial satin stainless, and 690 statuary dark bronze. Two are living finishes worth knowing about before you standardize a building on them: 613 is meant to wear over time into an antique appearance, and 690 continues as a dark brown. If you're matching a fleet of existing openings, 626 and 630 are the two that stay put.
10) Is a mortise lock the right choice over a cylindrical lever for a dorm or apartment door?
A mortise body like the 45HCA goes into a routed pocket in the door edge, not a bored hole, and it carries both a 3/4 inch latchbolt and a separate 1 inch deadbolt in one case. That combination is why it is specified for high traffic residential and institutional openings: one lock handles latching and deadbolting, and the 0.095 inch cold rolled steel case with an armored front around both bolts takes abuse a bored lock does not. The trade-off is prep. If your doors are already bored for cylindrical locks, converting to mortise means routing new pockets, and a cylindrical or interconnected lock is the cheaper path on that opening.
11) Will the BEST 45HCA hold up in a high traffic building, and what protects it from corrosion?
Case, cover and armored front are 0.095 inch cold rolled steel with zinc dichromate plating for corrosion protection. The latch is solid one piece stainless steel, oil impregnated for anti-friction operation, with 50 percent more surface contact against the strike than the previous design. Four case cover screws at each corner plus an interlocking armored front and cover at the latch hold the case together, and the hub runs on roller bearings with a lever return spring in the trim to fight lever droop, which is the failure mode you actually see on a dorm corridor after a few years.
12) Can the BEST 45HCA be electrified or tied into an access control system?
No. The 45HCA is a mechanical lock body with no electronic option, operated by key and by the hub toggle only. For card access or remote release on a mortise opening you need an electrified mortise lock or an electric strike specified separately.
13) What are security head screws on a BEST mortise lock order, and do I need them?
Security head screws are a required order choice, yes or no, on the 45HCA. They replace the standard fasteners with heads that resist removal by ordinary drivers. Worth taking on student housing, transit facilities and any opening where the lock is reachable and unsupervised. On a private office behind a controlled lobby they're usually not the thing that decides security.
