Installation & Operation

  1. Review manufacturer specifications and verify door preparation requirements including door thickness (standard 1-3/4" or up to 5" thick door configuration), mortise pocket dimensions, and handing requirements.
  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and frame surfaces for proper alignment of the self-aligning trim mechanism.
  3. Prepare door mortise pocket and frame strike preparation according to specifications, ensuring proper clearance for the armored front and strike box assembly.
  4. Install mortise lock case in door pocket and secure with appropriate fasteners, allowing the armored front to self-align with door bevel during installation.
  5. Configure four position hub toggle to determine locked/unlocked operation for each hub and adjust lever return spring mechanism for proper horizontal positioning.

BEST 45H0LT3J613VIB – Frequently Asked Questions

1) Will the BEST 45H privacy mortise lock fit a door thicker than 1-3/4 inches?
The standard 45H configuration is built for 1-3/4 inch doors. BEST does make a thick door configuration for doors up to 5 inches, but the thickness has to be specified at time of order, so it is not a field adjustment. Measure the leaf before you order.
2) Do I need to order a handing on the BEST 45H mortise lock?
Handing is a required selection (left hand, right hand, left hand reverse, right hand reverse), but the lock body itself is non-handed. The latchbolt reverses by rotating 180 degrees without opening the case, and there is a four position hub toggle for setting locked/unlocked operation on each hub. So if the opening turns out to be the opposite hand in the field, you can correct it on site.
3) Is the BEST 45H mortise lock ANSI Grade 1?
The 45H Series is certified to ANSI A156.13, Series 1000, Grade 1 for Operation and Strength, and Grade 2 for Security. Reaching Grade 1 Security on a 45H requires a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trims, or the 1EK7K4 high security cylinder with sectional trims. If a spec calls for Grade 1 across the board including security, the 47H Series carries Grade 1 Operational, Strength and Security as built.
4) Does the BEST 45H privacy lock come with a cylinder or core?
No. It ships less cylinder, and the privacy function is non-keyed. Any core or housing for an emergency release has to be sourced separately to match your existing BEST keying system.
5) What does the double visual indicator on the BEST 45H privacy lock actually show?
Two indicators, one on each side of the door. Unlocked shows an open padlock icon; locked shows a closed padlock icon painted red. That is what makes it work for restrooms, exam rooms, and single occupancy spaces where staff and occupants both need to read status without trying the lever.
6) What is the difference between the 626AM and 630AM antimicrobial finishes on the BEST 45H?
Both carry the UltraShield antimicrobial protected coating, which inhibits bacterial and microbial growth on the hardware surface. 626AM is satin chrome plated; 630AM is satin stainless steel. BEST recommends these for hospital and healthcare, elderly care, education, transportation, food service and hospitality. If you are standardizing a facility on a non-antimicrobial look, the same lock is offered in 605, 606, 611, 612, 613, 618, 619, 622, 625, 626, 629, 630 and 690.
7) What lever and trim options do I have to pick for the BEST 45H?
Three things get specified beyond finish and handing: trim style (H rose, R rose, or J wrought escutcheon), lever style, and the finish. Lever choices are 3 solid tube with return, 12 solid tube with no return, 14 curved with return, 15 contour with angle return, 16 curved without return, 17 gull wing, and 4 round knob. Note the security grading differs by trim: drill resistant cores pair with escutcheon trims, the 1EK7K4 high security cylinder with sectional trims. Levers include a return spring mechanism in the trim to resist lever droop.
8) Is the BEST 45H privacy mortise lock ADA compliant?
The design and operation of the BEST mortise lock meets the intent of ANSI A117.1 section 404.2.6. For an accessible opening, choose one of the lever options rather than the 4 round knob, since a knob is not operable without tight grasping.
9) What else could I use instead of the BEST 45H if I do not need a visual indicator?
For a plain Grade 1 privacy mortise lock with deadbolt, the Cal-Royal NM8440 covers privacy/bed/bath on a 1-3/4 inch door, and the Hager 3840S is a Grade 1 privacy mortise on a 2-3/4 inch backset for 1-3/4 to 2 inch doors. If you want the indicator but in a classroom security function rather than privacy, the Marks USA LA318GJ is a classroom security indicator mortise lockset for 1-3/4 inch doors. And if the requirement is electronic privacy with a keypad, the Schlage CO-100 mortise is a Grade 1 privacy function unit.
10) Why does the BEST 45H latch hold up better than a standard mortise latch in high traffic?
The latchbolt is solid one-piece stainless steel with roughly 50 percent more surface contact against the strike, and it is oil-impregnated for anti-friction operation with a curve profile cut for cycle life. The case, cover and armored front are 0.095 inch cold rolled steel, zinc dichromate plated against corrosion, and the armored front wraps both latch and deadbolt for lateral strength. The hub runs on a roller bearing. That is the package that gets it through ANSI Grade 1 strength on dorm, school and hospital traffic.
11) Is the BEST 45H an electronic or access control lock?
No, it is a purely mechanical heavy duty mortise lock with no electronics or wiring. If the opening needs credential or keypad control, look at an electrified mortise such as the Dormakaba E-Plex 5086 pushbutton/card mortise or the Schlage LE Series mobile enabled mortise lock.
