Sargent 73-43 26D – Frequently Asked Questions

1) Will the Sargent 73 small format mortise cylinder take a 7-pin core, or is it 6-pin only?
The 73 housing accepts both 6 pin and 7 pin cores, so one shell covers either keying depth. Ordering reflects that: sizes are listed as 6-Pin, 7-Pin, or as a shell that takes 6 or 7 pin, in both the 1-3/8 inch and 1-3/4 inch lengths. If you are standardizing a building on 7-pin for greater key change capacity, the same cylinder body works alongside 6-pin openings elsewhere in the same system.
2) Which length Sargent mortise cylinder do I need, the 1-3/8 inch or the 1-3/4 inch?
Two lengths are offered: the #43 at 1-3/8 inches (35mm) and the #46 at 1-3/4 inches (44mm), both measured under the cylinder head including the cam. The longer #46 is what you reach for on thicker doors or where a collar or spacer stacks the cylinder out from the lock face. Measure from the face of the lock trim to the cam drive on the lock you are servicing, not the door thickness alone, since trim and collars eat cylinder length.
3) Does the Sargent 73 cylinder come with a cam, and can I change the cam later?
The cam is permanently staked to the housing, so it ships as one assembly and is not a field-swappable part. It is the SARGENT offset cam, which is what mates with Sargent mortise lock bodies. If the lock you are working on needs a different cam style, this is the wrong cylinder for it, since the cam cannot be changed.
4) Will the Sargent 73 mortise cylinder work with my Sargent mortise locks already in the building?
It is built with the SARGENT offset cam specifically for compatibility with SARGENT mortise lock systems, and it runs on the conventional key system rather than an interchangeable-core large format setup. For a property manager or facilities crew rekeying a floor of Sargent mortise locks, this is the matching cylinder rather than a cross-brand substitute.
5) Can I order Sargent 73 mortise cylinders keyed alike across a set of doors?
Keying is a required selection: standard keying, KD (keyed different), or KA (keyed alike). Keyed alike is the choice when a maintenance crew or tenant needs one key to open several doors in a group. Keyway is also a required choice, standard or restricted, and restricted is the one to pick if you want key duplication controlled at the factory level for a building you manage.
6) Is the Sargent 73 an interchangeable core cylinder, or a conventional pinned cylinder?
It is a conventional key system cylinder. The core is not the removable figure-eight style you pull with a control key; the housing is pinned as a small format mortise cylinder in 6 or 7 pin. If your building is set up on removable core so a locksmith can rekey without disassembling the lock, this is not the part for that program.
7) What diameter is the Sargent 73 mortise cylinder housing, and will it drop into a standard mortise lock cylinder hole?
The housing is 1-5/32 inches (29mm) in diameter. That is the small format size, not the 1-5/32 inch standard mortise cylinder thread you find on a conventional Sargent 40 series mortise cylinder, so it goes into openings prepped for the small format housing. Check the existing cylinder you are pulling out before you order.
8) What finishes does the Sargent small format mortise cylinder come in to match my existing trim?
Fifteen finishes are offered: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BE dark oxidized satin bronze, 10BL dark oxidized satin bronze clear coated, 14 bright nickel, 15 satin nickel, 20D dark statuary bronze lacquered, 26D satin chrome over nickel, 32 bright stainless, 32D satin stainless, BSP black suede powder coat, and WSP white suede powder coat. For most commercial openings the match is 26D or 32D against satin chrome or stainless lever trim, and 10B or 10BE against oil rubbed bronze.
9) Do I need to order a collar or spacer with a Sargent 73 mortise cylinder?
Collars and spacers are separate line items, not included. You need one when the cylinder sits proud of or below the trim face after installation, which happens when the lock trim or an escutcheon adds thickness. If the cylinder ends up too deep, the alternative is stepping from the #43 at 1-3/8 inches to the #46 at 1-3/4 inches rather than shimming it.
10) Is this Sargent cylinder rated for commercial door traffic, or is it a residential part?
It is a commercial part, sold as a replacement cylinder for mortise locks in office buildings, schools, hospitals, retail, industrial facilities, multi-tenant residential, and government buildings. It is the service part you buy to rekey or replace a failed cylinder in an existing Sargent mortise lock, not a complete lock assembly.
