1. Solid one-piece stainless steel anti-friction latch provides 50% more surface contact with strike for superior strength and security. Reversible latch rotates 180 degrees for easy handing change without opening case. Precision-engineered curve provides enhanced cycle life with reduced wear to the strike.
2. Non-handed cylinder retainer and stainless steel auxiliary bolt for ease of changing hand.
3. Armored front completely surrounds latch and deadbolt providing increased lateral strength. Staked assembly design allows the armored front to self-align with the door bevel during installation.
4. Enhanced case integrity achieved through four case cover screws (one at each corner), plus interlocking armored front and cover design at the latch.
5. Roller bearing hub mechanism provides smooth, wear resistant operation.
6. Locking toggle includes clear indication of “locked” and “unlocked” states.
7. 40H case, cover, and armored front manufactured from 0.095” cold rolled steel for strength and durability.
8. Fusible link.
9. Four position hub toggle design determines whether each hub is always locked, always unlocked, or locked by key for easy handing change without opening case.
10. Lever return spring mechanism located in trim for enhanced protection against lever droop, providing a firm, positive return of the lever to the horizontal position.
11. Self-aligning trim mechanism for fast, easy, and accurate installation.
12. Curved lip strike and strike box assembly provides an aesthetic, non-handed solution to complement field reversible case.
13. Solid machined cylinder rings with tension spring provide resistance to wrenching of cylinder. Cylinder security screw prevents removal of cylinder without first removing interchangeable core.

Strength, Durability…and now Flexibility.
Sure, a mortise lock is one of the strongest and longest lasting locks available. But who says it has to be the most complex to order and install? When designing the 40H mortise lock, Best Access Systems decided to focus on things that would make the lock easier to use, while at the same time maintaining the strength, durability, and dependability you would expect in a BEST mortise lock. In addition to the ability to quickly change the lock handing, the universal case design of the 40H provides the ability to reconfigure a lock into many different functions easily and quickly, often by rearranging existing parts without disassembling the lock case. The efficiency of the design enables over 12 of the most commonly used lock functions to be included in just 3 case configurations. The 40H provides the ability to postpone decisions on how the lock will be configured all the way up to the point of installation, making it one of the most flexible and user-friendly mortise locks available. This translates into value for anyone involved in the process, whether they’re an architect, specification writer, distributor, or end-user.
Best Access Systems offers three ways in which to order the 40H mortise lock. YOU get to choose which method meets your needs.
Function Specific Lock
If you know exactly what you need in a mortise lock, and are confident that your needs won’t change, then order your 40H locks in the traditional way by specifying the exact function, trim, finish, and handing. BEST will build the locks to work exactly as specified, so they may or may not have the ability to be converted to another function in the future.
If you want to keep your options open, this method of ordering the 40H is for you. BEST has developed three “universal” functions that can be configured to a variety of common functions, all without opening the lock case. When any of the universal functions are ordered as a complete lock, all the necessary parts (including trim) are provided to configure any of the functions in that group.
For the maximum flexibility in ordering a mortise lock, BEST provides a way to order your 40H lock in three parts: Inside Trim, Case Only, and Outside Trim. The kits that make up these three parts have been carefully designed so that when all three are combined you have everything found in a complete 40H lock.
This order method is ideal for customers wanting to stock a variety of trim designs with a minimal number of lock cases.
No more searching through service manuals or calling technical support for the right part numbers. BEST has developed a variety of kits you can order when you only need part of a 40H mortise, rather than the whole lock.
A Case Only lock includes all parts normally included with a complete lock that are not specifically associated with either the inside or outside trim, including: lock case, faceplate, strike and strike box, fasteners (for case and strike), and installation instructions. Case Only mortise locks will be shipped in the standard mortise packaging, allowing trim kits to be included at a future date to make a complete lock.
A 40H Trim Kit is simply one half of a complete trim package. An Outside Trim Kit must always be matched up with an Inside Trim Kit to operate with a lock. Each kit includes all the necessary parts (including fasteners) required for installation that are associated with just the one side of the door.
The universal (non-handed) strike & strike box combination is supplied as standard for all 40H functions. For applications where the strike box cannot be installed in the frame, handed strikes can be ordered. Security Head screws are an option for this kit.
A lever set kit provides the inside lever assembly (with set screw) and outside lever assembly (with spindle attached). Thick Door and Tactile Lever options are available for this kit.
The Face Plate kit includes a finished faceplate and the appropriate screws. Security Head screws are an option for this kit.
As a security feature, the outside spindle on the 40H is designed to twist off during abuse before any internal damage to the lock occurs. The Replacement Spindle kit is a quick, easy, and inexpensive way to replace any spindles damaged by attack or abuse. This kit includes the inside and outside spindles, plus the pin to attach the outside lever.
Nothing’s more frustrating than spending time searching for the part number of a single screw. With the 40H Screw Kits, you don’t have to worry about that anymore. These kits have been designed to provide all the necessary fasteners for one lock in a single bag. All you need to know is the trim style and finish, and you’re set. Security head screws are an option for this kit.
With the introduction of the 40H mortise lock, BEST has decided to alter the mortise function letter designations to bring them in alignment with the BEST cylindrical lock functions. This way, a classroom lock will be “R” and a storeroom lock will be “D”, regardless of which lock family is used.
Lead Lined Feature – The 40H mortise lock can be lead lined to protect against x-rays. Since the majority of lead lined doors contain the lead in the surface of the door, the 40H provides lead lining for the holes cut in the door when preparing the door for the trim. The two holes that are lead lined are the lever hole and the cylinder hole. (except in double cylinder or non-keyed functions). To order: designate “LL” on order procedure (page 6-7)
Security Head Screws – Security head screws. To order: designate “SH” on 45H/47H in order procedure (page 6-7).
Tactile Feature Knob/Lever – This option is for use in applications where special notice is needed to warn the blind about safety or accessibility environments. Depending on the style ordered, the knob or lever will receive either grooves or knurling as the tactile feature. To order: designate “TL” on 45H/47H knobs/levers in order procedure (page 6-7).
Visual Indicators Feature – This option adds a visual indicator for certain functions that visually reflects whether the lockset is in the locked or unlocked position. This option is available for the following functions: TD– Dormitory, IND– Intruder, INL– Intruder, L– Privacy, LT– Privacy. It is standard on the H– Hotel function.
ED 211 Mortise Cylinder Wrench – The Best mortise cylinder wrench and test handle is an essential dual-purpose tool. It is used primarily to install or remove Best mortise cylinders without marring the cylinder surface finish. The single end may be used to test the lock operation, as well as align the throw pins.
To order specify: ED 211 mortise cylinder wrench.
ED 212 Mortise Cylinder Cam Assembly Tool – Mortise cylinder cams are quickly changed with the use of this tool. Approximate length 1 3/4".
To order specify:ED 212 assembly tool.
ED 221 Mortise Cylinder Thread Repair Die – Tool for rethreading 1 5/32" diameter cylinders.
To order specify: ED 221 thread repair die.
ED 225 Hole Tap for 1 5/32" Mortise Cylinder – Tap tool used to rethread housing threads for 1E Mortise Cylinders.
