BEST 45HCAS626 – Frequently Asked Questions

1) Does the BEST 45HCA mortise lock come with trim and cores, or is it just the lock body?
What you get is the lock body only. The 45HCA is a mortise lock case, prepped SFIC less core, so you order the levers or knobs, roses or escutcheons, and the small format interchangeable cores separately. Plan the trim and cylinders into the same order or the opening won't be operable when the case is in the door.
2) What does the double cylinder storeroom function on the BEST 45HCA actually do at the door?
Storeroom function with a double cylinder setup: the outside is always locked and is retracted by key only, and the case carries a 1 inch throw deadbolt plus a 3/4 inch throw latchbolt. Because it is double cylinder, the deadbolt is thrown and withdrawn by key from either side rather than by a thumbturn. That matters for egress, so check your local code before specifying it on an occupied room.
3) Do I have to specify handing on the BEST 45HCA, or is it reversible in the field?
Handing is a required selection, RH, LH, RHRB or LHRB, but the latch is reversible in the field. The latchbolt rotates 180 degrees without opening the case, and the hub toggle has four positions, so a locksmith can correct handing on site instead of returning the lock. The auxiliary bolt is non-handed.
4) Is the BEST 45HCA Grade 1, and what does it take to get Grade 1 security?
The 45H Series is certified to ANSI A156.13, Series 1000, Grade 1 Operation and Strength with Grade 2 Security. To reach Grade 1 Security you have to use a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim, or a 1EK7K4 high security cylinder with sectional trim. If your spec calls for Grade 1 across the board including security, the 47H Series carries Grade 1 Operational, Strength and Security as built.
5) Can I use the BEST 45HCA on a door thicker than 1-3/4 inches, or do I need a different lock?
The 45HCA standard configuration is built for 1-3/4 inch doors, with a thick door configuration available for doors up to 5 inches when the thickness is specified at order. Most comparable mortise locksets stop well short of that: the Cal-Royal NM8080 and NM8070 are listed for 1-3/4 inch doors, the Corbin Russwin ML2003 for 1-3/4 inch, and the Hager 3810E passage mortise for 1-3/4 to 2-1/2 inch. If your opening is a thick or oversized door, the 45HCA thick door configuration covers a range those do not.
6) What is a Grade 1 storeroom mortise alternative to the BEST 45HCA if I need the lever trim included?
The BEST 45HCA is a storeroom-function mortise lock body only, supplied with SFIC prep less core, so lever trim and core are ordered separately. If you want a storeroom mortise that arrives with lever trim, the Accentra 8805FL is a Grade 1 storeroom mortise lock with the Arcadia lever, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option. All three give you a keyed storeroom opening; the difference is whether you are building the opening from a lock body plus your own trim or buying a complete set.
7) If I want keypad or credential access on a storeroom door instead of a keyed mortise, what replaces the BEST 45HCA?
The 45HCA is a mechanical, non-electronic lock body. For access control on the same mortise prep, the Command Access ML190 is a heavy-duty storeroom function motorized mortise lock with field selectable EL/EU operation on 24VDC, the Schlage CO-100 is a Grade 1 standalone electronic mortise lock with keypad reader for 1-3/4 inch doors, and the TownSteel FME-2000 is a Grade 1 heavy duty mortise lockset with RFID. The ML190 is the closest match if you want to keep storeroom function and add electric control.
8) I need a classroom function mortise lock instead of storeroom - what should I order?
The BEST 45HCA is built as a double cylinder storeroom function and will not give you classroom operation. For a mechanical classroom mortise, the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset with auxiliary deadlatch. If the spec calls for classroom security with a visual indicator, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors.
9) Which finish should I order for a hospital or school where the hardware gets wiped down constantly?
Two antimicrobial finishes are offered on the 45HCA, 626AM satin chrome and 630AM satin stainless, both with the BEST UltraShield coating that inhibits growth of bacteria and other microbes on the hardware surface. BEST recommends UltraShield for healthcare, elderly care, education, transportation, food service and hospitality. Standard finishes run from 605 bright brass through 630 satin stainless and 690 dark bronze, fifteen in all.
10) What is the difference between the BEST 45HCA and a mortise deadbolt like the Sargent 4874?
They are not substitutes. The 45HCA is a full mortise lock body with a 3/4 inch stainless latchbolt plus a 1 inch throw deadbolt and a 2-3/4 inch backset, so it latches and secures the door from one case. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, which bolts the door but provides no latch, and the Kaba Ilco 185 Series is likewise a deadbolt function mortise lock. Use a deadbolt where a separate latch or exit device already handles the door.
11) For a healthcare or behavioral health corridor, is the BEST 45HCA the right mortise lock?
The 45HCA suits healthcare on the finish side, since it is offered in 626AM satin chrome and 630AM satin stainless with UltraShield antimicrobial coating. But if the opening needs ligature resistance, look at the TownSteel MRX-L-01, a Grade 1 heavy duty anti-ligature lever mortise lockset, or the MRX-A-01 ligature resistant arch trim version, both passage function for 1-3/4 inch doors, or the Marks USA 5PDN Grade 1 hospital passage push/pull paddleset. Those are passage devices, so they do not give the keyed storeroom control the 45HCA does.
12) What should I use instead of the BEST 45HCA on an office door where occupants need to lock and unlock from inside?
The 45HCA is a double cylinder storeroom lock, so the outside lever stays locked and is released only by key. For office or entrance control, the Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon on a 2-3/4 inch backset. For a dormitory or corridor pattern with a deadbolt, the Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and single cylinder deadbolt.
13) Is the 45HCA case strong enough for a high traffic entry that gets abused?
Built for it. The case, cover and armored front are 0.095 inch cold rolled steel, zinc dichromate plated against corrosion, with a solid one-piece stainless anti-friction latchbolt that BEST states gives 50 percent more contact surface with the strike. The hub runs on roller bearings for cycle life and less strike wear. It is rated commercial heavy duty.
14) What keeps someone from wrenching the cylinder or pulling the core out of a 45HCA?
Solid machined cylinder rings with a wavy washer resist cylinder wrenching, and a cylinder security screw blocks core removal. Security head screws are an ordering option on the lock as well. The locking toggle shows locked and unlocked state, with optional padlock icon indicators.
15) Can I standardize a whole building on the 45H series if some doors need classroom or privacy instead of storeroom?
The 45HCA covered here is the double cylinder storeroom function specifically. Other functions live under different 45H function codes, so you keep the same case size, 2-3/4 inch backset and faceplate across the building and change only the function and trim. That keeps door prep identical from opening to opening, which is the practical reason facilities standardize on one mortise series.
