Sargent SGT-8222 03 – Frequently Asked Questions

1) Will the Sargent 8222 mortise deadlock fit a 1-3/4 inch commercial door?
Yes. The 8222 is built for 1-3/4 inch door thickness with a 2-3/4 inch backset, which is the standard commercial mortise prep. If your doors are thicker or thinner than 1-3/4 inches, this is not the body to order.
2) Does the Sargent 8222 deadlock need to be ordered left or right hand?
No handing to specify. The 8222 deadbolt body is non-handed, so the same unit goes into a left or right hand door without modification. That makes it easy to stock one spare for a whole building.
3) Is the Sargent 8222 a complete lockset with a lever, or just a deadbolt?
Deadbolt only. The 8222 is a mortise deadlock body with no latch, no knob and no lever trim, keyed both sides. If you need a latch that retracts with a lever plus a deadbolt, you need a different 8200 Series function, not this one.
4) How does a double cylinder deadlock like the Sargent 8222 operate from the inside?
Key both sides. The 8222 projects and retracts the bolt by key from either the outside or the inside, with no thumbturn. That gives you control over egress, so check your local egress and life safety requirements for the opening before specifying double cylinder on a means of egress door.
5) Is the Sargent 8222 deadlock rated Grade 1 and UL listed?
It meets ANSI/BHMA A156.13 Series 1000, which is the Grade 1 mortise lock standard, and carries UL and ULC listings. That is the combination most institutional and government specs call out for commercial mortise hardware.
6) Can I key the Sargent 8222 into our existing Sargent master key system?
Yes. The 8222 accepts all Sargent key systems, including Degree, Signature, KESO and XC, so it can be brought into an existing Sargent keyway and masterkeying scheme. Because it is double cylinder, you will need two cylinders per door.
7) What is the closest mechanical alternative to the Sargent 8222 mortise deadlock if I need a keyed deadbolt without a latch?
The Sargent 8222 is a deadlock only - a double cylinder, non-handed mortise deadbolt with no latchbolt or trim. The Kaba Ilco 185 Series mortise lock is also a deadbolt function and is offered with no handing, so it covers the same idea of a mortise-cased keyed bolt on its own. Choose between them on keyway and key system: the 8222 works with Sargent key systems including Degree, Signature, KESO, and XC.
8) I need latching plus a deadbolt in one mortise case instead of a deadlock only - what should I order?
The Sargent 8222 projects and retracts a hardened steel deadbolt by key from either side and does nothing else; there is no latch, so a separate latching lockset is needed to keep the door closed. If you want one mortise body that both latches and throws a bolt, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors. For a keyed latching body on the same door instead, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option.
9) Is there an electronic equivalent to the Sargent 8222 double cylinder mortise deadlock?
Yes, if you want to drop keys on one side. The Alarm Lock DL4500DB is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad, for doors 1-5/8 to 1-7/8 inch thick. The Sargent 8222 stays fully mechanical, keyed from both outside and inside, on 1-3/4 inch doors. Pick the DL4500DB when you want audit-free code changes without rekeying; pick the 8222 when the opening has to stay on the building's Sargent key system.
10) My door is a 1 inch ornamental iron stile - can I use the Sargent 8222?
No. The Sargent 8222 is built for 1-3/4 inch door thickness with a 2-3/4 inch backset. For thin ornamental iron doors, the Marks USA 21AC and 22AC are double cylinder entrance mortise locks listed for 1 inch doors. Both give you key control from each side like the 8222, but in a case sized for the narrow stile.
11) For a door in a fire rated wall, is the Sargent 8222 the right pick over a fire rated mortise lock?
The Sargent 8222 is a double cylinder deadlock, which means a key is required to retract the bolt from the inside as well as the outside - so confirm your egress and life safety requirements before specifying it on a rated or occupied egress door. Where a fire rated mortise lock is called for instead, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with a fire rating and field reversible operation.
12) What strike comes with the Sargent 8222 deadlock?
Every 8222 ships with the 4-7/8 inch no-lip flat strike, part 78-0034, as standard. That is the ANSI-size flat strike for a standard hollow metal frame prep, so it drops into an existing 4-7/8 inch cutout.
13) What finishes can I get the Sargent 8222 deadlock in to match the rest of my doors?
Twelve finishes: bright and satin brass (03, 04), bright and satin bronze (09, 10), three dark oxidized satin bronze variations (10B oil rubbed, 10BE, 10BL clear coated), 20D dark statuary bronze lacquered, bright and satin stainless (32, 32D), plus black and white suede powder coat. Satin stainless 32D is the usual match for commercial openings.
14) What is a good alternative to the Sargent 8222 if I want keypad access instead of a key on a deadbolt?
For a keyless mortise deadbolt, the Alarm Lock DL4500 Series is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad, listed for 1-5/8 to 1-7/8 inch doors. The Sargent 8222 is purely mechanical and key operated both sides, so the DL4500 is the route if you want codes instead of cutting keys.
15) I need a mortise lock with a lever and a latch, not just a bolt. What should I order instead of the Sargent 8222?
The 8222 has no latch or trim, so it will not serve as a primary lockset. For a keyed lever lockset in a 1-3/4 inch door, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset, and the Cal-Royal NM8050 covers office/entrance with an auxiliary deadlatch. Use the 8222 only as an auxiliary deadbolt or on a door that needs nothing but a bolt.
16) Will a Schlage L Series or BEST 45H mortise lock body substitute for the Sargent 8222?
No. The BEST 45H heavy duty mortise lock bodies are latching lock bodies in public entrance and intruder functions, and the Schlage L0170 is half dummy trim with no operating latch or bolt at all. The Sargent 8222 is a deadlock: a key-operated deadbolt in a mortise case with no lever or knob function. They are not interchangeable in the same pocket prep without confirming the door's mortise cutout and cylinder locations.
17) How does the Sargent 8222 compare to a credential-based mortise lock for a multi-tenant building?
The Sargent 8222 is a mechanical double cylinder deadlock; access changes mean rekeying cylinders on the Sargent key system. Credential alternatives in mortise format include the Dormakaba E-Plex E5086, a Grade 1 back to back pushbutton and card mortise lock, and the Schlage Electronics LEBMB-ADD mobile enabled mortise lock covering privacy, office, and apartment functions on 1-3/4 inch doors. The LEBMB-ADD is Grade 2, the E5086 is Grade 1, and the 8222 is Grade 1 under ANSI/BHMA A156.13 Series 1000.
18) Can a Baldwin 6301 or 6310 mortise body replace the Sargent 8222?
No, the preps differ. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies use a 2-1/2 inch backset, while the Sargent 8222 is a 2-3/4 inch backset deadlock. The Baldwin bodies are also knob or lever operated latching locksets, not a deadbolt-only case. Swapping one for the other means a different mortise pocket and cylinder centerline.
19) Is the Kaba Ilco BR bottom rail lock an alternative for a glass storefront door?
For an all-glass door, the Sargent 8222 is not the part - it is a mortise deadlock built for 1-3/4 inch doors with a mortise pocket. The Kaba Ilco BR Series is a glass door bottom rail lock made for that opening. Reserve the 8222 for hollow metal or wood commercial doors that can take the mortise prep.
20) What mortise option should I look at for a behavioral health or anti-ligature opening instead of the 8222?
The Sargent 8222 is a keyed deadlock with cylinders on both faces and no ligature-resistant trim. For those rooms, TownSteel offers the MRX-A-01 with satin stainless ligature resistant arch trim and the MRX-L-01 anti-ligature lever, both Grade 1 heavy duty passage mortise locksets for 1-3/4 inch doors - the same door thickness the 8222 is built for.
21) Is the Sargent 8222 deadlock heavy duty enough for a high traffic entrance?
It uses a one-piece hardened steel deadbolt and is classed for commercial use, with Grade 1 performance under ANSI/BHMA A156.13. Sargent lists it for office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and government facilities.
