BEST 45HCALT626 – Frequently Asked Questions

1) Does the BEST 45HCA privacy mortise lock come with trim and levers, or is it just the lock case?
What ships is the mortise lock body alone, field reversible. Levers, roses or escutcheons, and the strike package are separate items you specify to match the opening. Plan on ordering trim in the same finish as the case front so the opening looks consistent.
2) Will the BEST 45HCA privacy mortise lock fit a 1-3/4 inch door?
Yes. The standard configuration of the 45H mortise case is built for 1-3/4 inch doors, which is the usual commercial thickness. For thicker doors, a thick-door configuration covers up to 5 inches, but you have to specify the thickness when you order it. Backset is 2-3/4 inches, so the door pocket has to be routed for that.
3) Do I need to order the BEST 45HCA privacy lockbody handed?
Handing is a required selection (RH, LH, RHRB or LHRB), but the latch is reversible in the field without opening the case: it rotates 180 degrees, and there is a four position hub toggle for configuration. So if the door turns out to swing the other way on install day, you can change it on the job rather than reordering.
4) Is a privacy mortise lock keyed, and can I get into the room in an emergency?
The 45HCA privacy function is non-keyed. It is the bed and bath type function, thumbturn or pushbutton inside, with no cylinder keying. If you need a room that staff or security can key into, the privacy function is the wrong choice and you want a keyed function in the same 45H case instead.
5) Will the 45HCA latch into the strike that is already in my frame?
The latchbolt throws 3/4 inch and the deadbolt throws 1 inch, both stainless steel, off a 2-3/4 inch backset. If the existing frame prep was cut for a 2-3/4 inch backset mortise lock with the same lip-to-center strike, it will latch. A 7/8 inch lip-to-center strike is a selectable option when ordering, which is how you match a frame whose strike sits at that dimension.
6) What ANSI grade does the BEST 45H mortise lock meet?
ANSI A156.13, Series 1000, Grade 1 for Operation and Strength, with a Grade 2 Security rating. To reach Grade 1 Security you have to pair it with a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) on escutcheon trims, or the 1EK7K4 high security cylinder on sectional trims. The 47H series carries Grade 1 on all three, including security, if your spec calls for that outright.
7) What size door prep and faceplate cutout does this BEST mortise lock need?
The case is 5-7/8 x 7/8 x 4-1/16 inches and the faceplate is 8 x 1-1/4 x 1/16 inches, so the door needs a mortise pocket and face rout sized to that with a 2-3/4 inch backset. The armored front self-aligns to the door bevel during installation, so you do not have to bevel the face separately.
8) Which finish should I pick for a hospital or patient restroom?
For healthcare, elderly care, education, food service and transportation, BEST offers UltraShield antimicrobial finishes: 626AM satin chrome and 630AM satin stainless steel. The coating inhibits growth of bacteria and other microbes on the hardware surface. The other thirteen finishes run from 605 bright brass through 690 dark bronze, including 613 oil rubbed bronze, which is meant to wear to an antique look over time.
9) Does the BEST 45HCA take a small format interchangeable core?
The case comes prepped for BEST SFIC, less core, so the core is ordered separately and keyed to your system. On the privacy function there is no keying, but the SFIC prep is what makes the 45H family standardize across a building: the same core platform carries through the keyed functions on your other doors.
10) Is a mortise lock the right choice here, or should I use a cylindrical lever lock?
A mortise case like the 45HCA goes into a routed pocket in the door edge rather than a bored hole, and it carries both a 3/4 inch latchbolt and a separate 1 inch deadbolt in one case. That is what you want on heavy commercial traffic, where it is rated Grade 1 for operation and strength. A cylindrical lever is faster and cheaper to install on a bored door, but if the door is already mortise prepped, or the spec calls for a deadbolt in the same case, the mortise lock is the one that fits.
11) What are the security head screws option on the BEST 45H mortise lock for?
It is a required yes or no choice at order time. Security head screws resist removal with common drivers, which matters in corrections, schools, transit and any opening where the hardware itself is a target. The case also uses four cover screws at the corners with an interlocking armored front and cover at the latch, and a cylinder security screw that prevents core removal.
12) Is the BEST 45HCA an electrified or access control lock?
No. It is a mechanical mortise case with no electrical option. If the opening needs card access, remote release or monitoring, this is not the lock body for it.
