Kaba Ilco 185-F-3-NH-628/313 – Frequently Asked Questions

1) Will the Kaba Ilco 185 deadbolt fit an aluminum storefront door?
That's exactly what the 185 Series is built for. It's a mortise deadbolt for aluminum stile doors, offered in three backsets to match the stile you're working with: 31/32 inch, 1-1/8 inch, and 1-1/2 inch. Measure from the face of the stile to the centerline of the cylinder hole and order the backset that matches. Get the backset wrong and the cylinder won't line up with the prep in the door.
2) Should I order the straight deadbolt or the hookbolt version of the Ilco 185?
Single leaf door into a frame or jamb: straight bolt. It throws 1-3/8 inches with a bolt measuring 5/8 inch wide by 2-7/8 inches long, so it buries deep into the strike. Pair of doors meeting each other, or a sliding leaf, where there's no solid jamb to throw into: hookbolt. The hook throws 13/16 inch and measures 5/8 by 1-3/8 inches, and it catches and pulls rather than relying on depth. Both are on the same lock body and both come in all three backsets.
3) What cylinder does the Kaba Ilco 185 take, and is it included?
The 185 body accepts a standard 1-5/32 inch (29.36 mm) threaded mortise cylinder in zinc or brass. That's the common storefront mortise cylinder length, so most keyways and most keying systems you already run in the building will go straight in. It's a single cylinder deadbolt, so you key the outside and get a thumbturn or plain inside. Order the cylinder to your keyway separately, along with a strike to suit the frame.
4) Can an Ilco 185 deadbolt replace a 451 Series deadlatch in the same door?
Yes. The 185 is interchangeable with the 451 Series deadlatches, so it drops into the same prep. That's the usual move when a storefront door with a latch keeps getting pushed open and you want a dead throwing bolt instead. Match the backset of the unit coming out (31/32, 1-1/8, or 1-1/2 inch) and the cylinder hole lines up.
5) What do I use instead of the Ilco 185 if the door is a 1-3/4 inch hollow metal door that needs a lever and a deadbolt?
The Ilco 185 is a deadbolt only, with no lever trim, and its 31/32 inch through 1-1/2 inch backsets are sized for aluminum stile doors. For a 1-3/4 inch door that needs both latch and deadbolt from one lock, the Cal-Royal NM8440 is a Grade 1 mortise lockset with a deadbolt in a privacy/bed/bath function for 1-3/4 inch doors, and the Sargent 7925 is a Grade 1 heavy duty corridor/dormitory function mortise lock with rose trim and a single cylinder deadbolt. Pick by function: the NM8440 for a privacy opening, the 7925 for a corridor or dormitory door.
6) What is the difference between the Kaba Ilco 185 mortise deadbolt and a Sargent 4874 mortise deadbolt?
Both are mortise deadbolts, but they are built for different door types. The Ilco 185 is a single cylinder deadbolt made for aluminum stile doors, with backsets of 31/32 inch, 1-1/8 inch and 1-1/2 inch to suit narrow stiles, and a five-ply laminated steel bolt with a concealed hardened steel pin. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, a dimension that belongs to a wide stile wood or hollow metal door. If the door is an aluminum storefront stile, the 185 backsets are the ones that will land in the stile; if the opening is a standard 2-3/4 inch backset door and you need key operation on both sides, the 4874 is the one shaped for it.
7) I need a keyless electronic deadbolt instead of a keyed mortise deadbolt - what is the alternative to the Ilco 185?
The Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad, fitting doors 1-5/8 inch to 1-7/8 inch thick. The Ilco 185 is a mechanical, non-electronic deadbolt that is operated by a standard 1-5/32 inch threaded mortise cylinder, so access is by key and by rekeying the cylinder. Choose by how the door is managed: code changes handled at the keypad point to the DL4500, and keyway control on an aluminum stile door points to the 185.
8) Do I have to specify handing when ordering an Ilco 185 mortise deadbolt?
No handing to specify. The 185 is a deadbolt with no latch and no lever, so it works the same on a left or right hand door. That also means one part number covers every opening in a building, which is worth knowing if you're stocking spares for a storefront with mixed handing.
9) Is the Ilco 185 mortise deadbolt strong enough for a high traffic commercial entrance?
It's a commercial unit and cycle testing on the 185 exceeds ANSI Grade 1 standards. The bolt is five-ply laminated steel with a concealed hardened steel pin, which is what defeats a saw attack on the bolt itself, and the case is steel with corrosion resistant plating for exterior openings. On a retail or office storefront that gets locked and unlocked twice a day every day, that's the right class of hardware.
10) I need keypad or card access on my storefront door instead of a key. What should I look at?
The 185 is a mechanical, key only deadbolt with no electronics in it. If you want code or credential entry on that opening, the Alarm Lock DL4500 is an electronic mortise deadbolt with 2,000 user codes for doors 1-5/8 to 1-7/8 inches thick, and the Alarm Lock DL1300NW is a wireless keypad mortise lock made specifically for Adams Rite style deadlatches in aluminum storefront. The Dormakaba E-Plex 2066 is another pushbutton keyless mortise option, in wide stile.
11) Will the 185 deadbolt latch into the strike I already have in the frame?
Depends which bolt you order. The straight bolt throws 1-3/8 inches, so it needs a strike with a pocket deep enough to take that; most storefront jambs and existing deadbolt preps handle it. The hookbolt only throws 13/16 inch but swings a hook, so it needs a hookbolt strike or keeper, not a flat deadbolt strike. Swapping bolt types on an existing opening usually means changing the strike as well.
12) Can a Schlage PM010 or Falcon MA101 be used in place of the Ilco 185?
No, those are latching locks and not deadbolts. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock, both passage/hall/closet function, meaning the door is held closed but not locked. The Ilco 185 is a keyed single cylinder deadbolt that throws a five-ply laminated steel bolt with a concealed hardened steel pin. If the opening needs to be secured with a key, a passage lock will not do the job regardless of grade.
13) Is the Dormakaba E-Plex E2066 a substitute for the Ilco 185 on a storefront door?
They serve the same narrow-stile aluminum door but differently. The Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock built for wide stile doors, while the Ilco 185 is a mechanical single cylinder deadbolt for aluminum stile doors, offered in 31/32 inch, 1-1/8 inch and 1-1/2 inch backsets and in straight bolt or hook bolt. Confirm the stile width first: the E2066 is specified as wide stile, and the 185 backset range is what lets it sit in a narrower stile.
14) What is the electronic equivalent of the Ilco 185 for an aluminum storefront with a deadlatch?
The Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with a keypad made for Adams Rite deadlatches, which is the narrow stile storefront application. The Ilco 185 is a mechanical deadbolt for aluminum stile doors and is interchangeable with 451 Series deadlatches. The distinction is what the existing prep in the stile was cut for and whether the door is to be managed by credential or by key.
15) Do I need the Ilco 185 hook bolt or the straight bolt version, and is there a wood door alternative?
On a single leaf door the straight bolt is the usual choice: it is 5/8 inch wide by 2-7/8 inch long with a 1-3/8 inch throw. The hook bolt is 5/8 inch by 1-3/8 inch with a 13/16 inch throw and is the one that engages where a sliding or double door leaf has no fixed jamb to bolt into. Both come in 31/32 inch, 1-1/8 inch and 1-1/2 inch backsets. Neither suits a standard 1-3/4 inch wood or hollow metal door - for that, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors.
16) We are standardizing a facility on Grade 1 mortise hardware - how does the Ilco 185 fit alongside Grade 1 locksets?
The Ilco 185 cycle testing exceeds ANSI Grade 1 standards, and it is a commercial deadbolt with a steel case and corrosion resistant plating. It covers the aluminum stile openings, where its 31/32 inch to 1-1/2 inch backsets fit. For the interior 1-3/4 inch doors in the same facility, Grade 1 mortise locksets in the set include the Cal-Royal NM8080 for storeroom function, the Cal-Royal NM8070 for classroom, and the Accentra 8805FL storeroom mortise lock with Arcadia lever. Keying can be unified because the 185 accepts a standard 1-5/32 inch threaded mortise cylinder in zinc or brass.
17) Is a Sargent 130KB thumbturn an alternative to the Ilco 185?
No. The Sargent 130KB is a standard mortise thumbturn, and the Sargent 130W is a mortise thumbturn with a round backplate - both are trim that turns a bolt, not the lock body that carries it. The Ilco 185 is the mortise deadbolt itself, with a five-ply laminated steel bolt and a concealed hardened steel pin, keyed by a standard 1-5/32 inch threaded mortise cylinder. If what is worn out is the turn on the inside of the door, a thumbturn is the part; if the bolt or case is the problem, it is the 185.
18) Can I get the Ilco 185 in a finish that will hold up outdoors on a street facing entrance?
The Ilco deadbolt line comes in 7 standard finishes plus two Premier finishes: 32D satin stainless steel and 03P permanent polished bright brass over stainless steel. The Premier pair are the ones to specify on a sun and weather exposed storefront, since they are built to hold their appearance rather than dull off. The lock case itself is steel with corrosion resistant plating regardless of finish choice.
19) Is a Marks USA 21AC or 22AC ornamental iron mortise lock the same kind of narrow door lock as the Ilco 185?
Both address thin doors but in different constructions. The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with a round knob, listed for 1 inch doors. The Ilco 185 is a single cylinder deadbolt for aluminum stile doors with 31/32 inch, 1-1/8 inch and 1-1/2 inch backsets and no knob or lever trim. If the door is ornamental iron and needs a knob and latching entrance function, the 21AC and 22AC are built for it; if it is an aluminum storefront stile needing a bolt only, the 185 is the shape that fits.
20) How many locks come in a Kaba Ilco 185 mortise deadbolt order?
One lock body per order, sold as a single pack. If you're standardizing a run of storefront entrances you order one per door, and the cylinders and strikes come separately so you can key the whole set alike through one keyway.
