2INTRODUCING THE 40H LOCKOVERVIEWThe 40H Series Lock was designed to be easy to use,while at the same time maintaining the strength,durability, and dependability expected of a BESTmortise lock. In addition to the ability to quicklychange the lock handing, the universal case design ofthe 40H Series Lock provides the ability toreconfigure a lock into many different functionseasily and quickly, often by rearranging existingparts without opening the lock case. The 40H SeriesLock lets you postpone decisions about how the lockwill be configured all the way up to the point ofinstallation, making it one of the most flexible anduser-friendly mortise locks available.WAYS TO ORDERThere are three ways to order 40H Series Locks—function-specific locks, universal locks, and threepart locks.Function-specificlocks40H Series Service ManualIf you know exactly what you need in a mortise lockand are confident these needs will not change, orderyour 40H Series Locks in the traditional manner byspecifying the exact function, trim, finish, andhanding. The lock will be built to work exactly asspecified, so it may not have the ability to beconverted to another function.2–1
Introducing the 40H LockUniversal locksOrder a universal lock to allow for the option of changing functions tomeet future needs. Three universal functions are available that can beconfigured to a variety of common functions, all without opening thelock case. When any of the universal functions are ordered as acomplete lock, all necessary parts (including trim) are provided toconfigure any of the functions in that group. Universal locks can only beordered with sectional (rose) trim. If escutcheon (J/M/N) trim isneeded, order a three-part lock as described below.Three-part locksFor maximum flexibility, a 40H Series Lock can be ordered in threeparts—inside trim, case only, and outside trim. The kits associated witheach of the three parts are designed so that when combined, allnecessary components of a 40H Series Lock are present. This method ofordering is ideal for customers who want to stock a variety of trimdesigns with a minimal number of lock cases.THE ADVANTAGE OF KITSOften a service manual is nothing more than a parts catalog. With40H Series Locks, we’ve raised the bar regarding the ease of ordering,installing, and maintaining the lock. This service manual reflects thisstreamlined approach.When you order a part kit, rather than individual components, you getpeace of mind knowing that the manufacturer has already gone throughthe work of matching up the right parts to ensure they all worktogether and, more importantly, that you get all the pieces you’ll need.Through the use of nomenclature, you specify what you need based onthe required application, and the factory assembles the appropriateparts to fill that need.WORKING WITH UNIVERSAL FUNCTIONSThe universal case design allows a number of common functions to beconfigured starting from three universal functions. Some functions canbe configured using the parts provided when ordering the completelock. Others require additional or different trim that is applied to theuniversal case assembly. Also, some of the functions normally includedin the universal locks have unnecessary internal parts that are removedwhen the lock is ordered as a specific function, limiting their ability tobe converted to other functions.2–240H Series Service Manual
Introducing the 40H LockThe table below summarizes the conversion capabilities of the40H Universal Function Locks.What is the default function for the universallock?Which functions can be configured whenordering a universal lock?Which functions can be built from a universalcase, but require additional or different trim?Which functions found in universal locks haveparts removed when they are ordered as specificfunctions, limiting their ability to be converted?UNRRUNTTUNABABA, AT,D, N,NX, RL, TAB, TA,TDC, INL,ZD, XR,WINDH, HJA, N,NXLTA, TDThe following functions must always be ordered by their specificfunction letters and require the case to be opened when converting to adifferent function: B BW LT B5 CHB RHB B7 G S BA LBWORKING WITH TRIM KITSA 40H trim kit is half of a complete trim package. An outside trim kitmust be matched with the appropriate inside trim kit to operate with alock. Each kit includes all parts, including fasteners, required forinstallation of the trim on one side of the door.Because many lock functions share a common case assembly and differonly in trim, using trim kits is an easy and efficient way to convertbetween functions. The table below shows how to match theappropriate inside trim kit and outside trim kit with each function.

These specializedconfigurations require a special letter designation to be appended to thefunction letter. If the inside trim is removed, a “Z” is added to the standard functionletter. If the outside trim is removed, an “X” is added to the standardfunction letter.The following table shows common applications with theircorresponding speciality function nctionClassroomRXRR function less outside trimStoreroomDXDD function less outside trimUtilityDZDD function less inside trimClosetRZRR function less inside trimDescriptionAlthough only XR and ZD functions are included in this manual, nearlyall 40H functions can be configured as X or Z functions.
