Falcon 1792NL-OP/HB-OP 1790 Series Narrow Stile Rim Exit Device - 48"

The Falcon 1792NL-OP/HB-OP is a Grade 1 rim exit device built for 48" narrow stile aluminum doors. It carries ANSI/BHMA A156.3-2001 certification and ships with the 179CA rim cylinder and TD35 strike as standard equipment. The device is non-handed and fits 1-3/4" door thickness. Latch throw is 3/4" with a 3-3/8" projection. All mounting screws are concealed. An optional RX request-to-exit switch is available as a variant on this listing.

Night Latch / Hold Back Cylinder Function

  • Night Latch (NL): Key retracts the latch without unlocking the exit device, allowing controlled after-hours entry while maintaining panic egress at all times.
  • Hold Back (HB): Key retracts and holds the latch in the open position, permitting unrestricted traffic flow when required.
  • Optional Pull (OP): Pull hardware is field-selectable; the device ships less trim.

Falcon 1792NL-OP/HB-OP 48IN US26D – Frequently Asked Questions

1) Does the Falcon 1792 exit device work on a 1-3/8 inch door or a thicker 2 inch door?
No. The 1792NL-OP/HB-OP is a single-thickness device, set up for 1-3/4 inch doors only. If your leaf is thicker, the Adams Rite 8800 Series narrow stile rim device covers 1-3/4 to 2-1/4 inches, and the DORMA 9300 Series wide stile device covers the same 1-3/4 to 2-1/4 inch range. For a thinner door, neither this nor those alternatives is rated for it.
2) What is the difference between night latch and hold back on a Falcon 1790 Series exit device?
Two behaviours off the same cylinder. Night latch lets a key pull the latch back for one entry without unlocking the device, so an after-hours employee gets in but the door relocks behind them. Hold back turns the key and parks the latch retracted, so the door stays free-swinging for a delivery window or a busy period, then you key it back. Egress from inside is unaffected either way, since the pushbar always releases the latch. That's the NL/HB pairing in the 1792NL-OP/HB-OP.
3) Does the Falcon 1792NL-OP/HB-OP come with a strike and cylinder, or do I order those separately?
The TD35 strike ships standard with the device, and the 179CA rim cylinder is included as well. What is not included is the outside pull. The OP suffix means optional pull, so the device ships less trim and you pick the pull hardware in the field. Budget for that pull on the order, plus keying for the rim cylinder if you're matching an existing system.
4) Will the Falcon 1792 latch into the strike already on my aluminum door frame?
Latch throw is 3/4 inch, and the device is supplied with its own TD35 strike. On a retrofit the safe move is to install the TD35 rather than reuse whatever is in the jamb, because rim strike lip position and pocket depth vary by manufacturer and a 3/4 inch throw needs the pocket to match. The TD35 is included, so there's no added cost to doing it right.
5) Can the Falcon 1790 Series replace an old crossbar panic device on a storefront door?
Yes, it's set up as a retrofit for 2090 Series crossbar devices. You're swapping a crossbar for a pushpad, which is generally what building owners want anyway for appearance and for a cleaner face on glass doors. Confirm the leaf is 48 inches and 1-3/4 inches thick, since that's what this size covers.
6) Does the Falcon 1792 exit device meet Grade 1 for a school or hospital spec?
Grade 1, certified to ANSI/BHMA A156.3-2001. That's the exit device standard and the top duty grade under it, which is what most institutional and government specs call for on egress hardware. It's a commercial device, and the mounting screws are all concealed, which cuts down on tampering in high-traffic corridors.
7) What electrified options can I order on the Falcon 1792NL-OP/HB-OP, and what does each one do?
Three, and they solve different problems. RX is a request-to-exit switch that signals your access control panel when someone pushes the bar, so the alarm doesn't trip on a legitimate exit. EL is electric latch retraction: the panel pulls the latch back remotely, so a card reader or a timer can unlock the opening while the pushbar still works mechanically. ED is electric dogging, which holds the latch retracted during business hours on a schedule instead of someone walking around with a hex key. RX is a finish-level choice on the device; EL and ED are ordered as options.
8) Should I use a narrow stile rim exit device or a wide stile one on my door?
It comes down to how much flat face you have between the glass and the door edge. Aluminum storefront and curtainwall leaves have a thin stile, and a wide stile pushpad chassis won't land on it, which is why the Falcon 1790 Series is built narrow. On a hollow metal or flush door with a broad stile, a wide stile device gives you a longer pushpad and more trim choices, for instance the Corbin Russwin ED5200 or the Von Duprin 22 Series, both Grade 1 wide stile rim devices for 1-3/4 inch doors. Measure the stile before you order; that decision can't be reversed after the door is prepped.
9) I need a fire rated narrow stile rim exit device. Is the Falcon 1792 the right one?
No, look elsewhere for a labeled opening. For a fire rated narrow stile rim device, the Adams Rite 3700 Series is fire rated, Grade 1, narrow stile, and is also listed for wood doors. If the opening is wide stile, the Marks USA M9900F is available fire rated in both 36 and 48 inch sizes, and the Orca OED85 Series is a 36 inch fire rated rim device. Note that fire rated devices don't offer dogging, so you lose the hold-open behaviour the 1792 gives you.
10) Can I use the Falcon 1792 rim device on a pair of doors?
Only with a removable mullion between the leaves. A rim device latches into a strike at the jamb, so on a pair with no mullion there's nothing for it to catch. For a mullion-free pair you want vertical rod hardware instead, which latches at the head and sill: the Hager 4601 Series is a Grade 1 concealed vertical rod device with a narrow stile pushpad, and the Hager 4501 Series is the wide stile concealed rod equivalent.
11) What is the closest narrow stile rim exit device to the Falcon 1792NL-OP/HB-OP for a 48 inch aluminum storefront door?
The Falcon 1792NL-OP/HB-OP is a Grade 1 narrow stile rim exit device at 48 inches, non-handed, for 1-3/4 inch doors, and it is not rated for wood doors. The Corbin Russwin ED4200 is also a Grade 1 narrow stile rim device for 1-3/4 inch doors and not wood door compatible, in a 36 inch size, and its function is listed as exit only, accepts trim. The TownSteel ED8900 and TownSteel ED3700 are Grade 1 heavy duty narrow stile rim devices at 36 inches, also not wood door compatible. If the opening truly needs a 48 inch device, the Falcon is the narrow stile one at that length; the narrow stile peers here are catalogued at 36 inches.
12) I need a night latch function rim exit device on a narrow stile door - what are the options besides the Falcon 1792NL-OP/HB-OP?
The Falcon 1792NL-OP/HB-OP carries a night latch / hold back cylinder function, where the key retracts the latch without unlocking the device and can hold it back for open traffic. The Sargent 8504 is a Grade 1 narrow stile rim exit device whose function is listed as night latch, so it covers key-retracts-latch entry on a narrow stile door but is catalogued without the hold back half. On the wide stile side, the Detex V4003A/03AN is a Grade 1 wide stile rim device supplied with night latch trim. Choose on stile width first: an aluminum storefront door generally takes the narrow stile bodies.
13) The Falcon 1792NL-OP/HB-OP is not fire rated - what narrow stile rim device do I use on a fire rated opening?
For a fire rated opening, the Adams Rite 3700 Series is a Grade 1 narrow stile rim exit device with a fire rating, offered at 30 inches and rated for wood doors as well. The Arrow FS1250 is a fire rated 32 inch rim exit device for 1-3/4 inch doors, not wood door compatible. Marks USA M9900F is a fire rated rim exit device, exit only, offered in both 36 inch and 48 inch sizes, and Dexter's ED1000 Series fire rated version is Grade 1. The Falcon 1792NL-OP/HB-OP is the Grade 1 narrow stile choice on non-rated aluminum storefront openings.
14) My door is a wide stile hollow metal door, not aluminum storefront - is the Falcon 1792NL-OP/HB-OP still the right exit device?
The Falcon 1792NL-OP/HB-OP is built as a narrow stile device, so a wide stile door calls for a wide stile body instead. At 48 inches, the Dormakaba 9300 Series is a Grade 1 heavy duty wide stile rim exit device, exit only, for 1-3/4 inch to 2-1/4 inch doors. The Corbin Russwin ED3200 is a Grade 1 wide stile crossbar rim device at 48 inches for 1-3/4 inch doors, and the Sargent 3828 is a Grade 1 reversible wide stile push bar rim device for 48 inch doors. All three are non-fire-rated like the Falcon, except the Sargent 3828, which is catalogued without a fire rating value.
15) What looks like a substitute for the Falcon 1792NL-OP/HB-OP but is not a panic exit device?
Two things in the same aisle are not mechanical panic hardware. The SDC MSB550 Series is a mechanical switch bar that releases an electromagnetic lock, and the SDC SureExit PSB560 Series is a pressure sense bar with tri-failsafe technology - both are 36 inch bars fitting narrow or wide stile doors, but they signal a lock rather than throw a latch. The Detex Advantex 00 Series is a dummy exit device with wide stile design, meaning it has no latching function at all. The Falcon 1792NL-OP/HB-OP is a mechanical Grade 1 rim device with a 3/4 inch latch throw and a TD35 strike, so it latches the door on its own.
16) Do I need to specify handing for the Falcon 1790 Series rim exit device?
No handing to call out. The 1792NL-OP/HB-OP is non-handed, so one part number covers left and right hand openings. That matters if you're stocking spares for a building with doors swinging both ways: one device on the shelf serves any of them.
17) What finishes does the Falcon 1790 Series narrow stile exit device come in for matching storefront doors?
Five: US28 aluminum anodized, DC13 dark bronze anodized, DC35 black anodized, US26 bright chrome, and US26D satin chrome. The three anodized options are the ones that match typical storefront framing, clear aluminum and dark bronze being the two most common curtainwall finishes. Every finish can be had with or without the RX switch.
18) Can I add the RX switch to a Falcon 1790 Series device I already have installed?
Yes. Falcon publishes an RX switch retrofit kit with installation instructions covering the 1690, 1790 and 2390 devices, so an existing 1790 in the field can be converted rather than replaced. If you're buying new and already know the opening ties into access control, ordering the device with RX from the start saves the labour of pulling it off the door later.
19) I'm standardizing exit hardware across a building with different door widths. Does the Falcon 1790 Series help?
It does within its limits. The 1790 Series is non-handed, so you don't split your spare stock by hand, and the 1792NL-OP/HB-OP covers 48 inch narrow stile leaves at 1-3/4 inches. Openings narrower than that need a shorter device from the same series, and any wide stile or wood door in the building needs different hardware entirely, since this one is not wood door compatible. Keying is the other half of standardizing: the rim cylinder ships with the device, so specify your keyway and keying up front to keep the whole building on one key.
20) Is the Adams Rite 8800 a drop-in alternative to the Falcon 1792NL-OP/HB-OP?
They are both Grade 1 narrow stile rim exit devices not rated for wood doors, so they suit the same class of aluminum opening, but they are not interchangeable hardware. The Adams Rite 8800 Series uses starwheel interlocking and covers a 1-3/4 inch to 2-1/4 inch door thickness range, and is catalogued at 30 inches; the Falcon 1792NL-OP/HB-OP is a 48 inch device fitting 1-3/4 inch doors with a 3/4 inch latch throw and 3-3/8 inch projection, supplied with the TD35 strike. An interlocking device engages the frame differently from a rim latch into a surface strike, so the strike prep does not carry over.
21) If Grade 1 is not required by my spec, is there a lighter duty 48 inch rim exit device instead of the Falcon 1792NL-OP/HB-OP?
The Falcon 1792NL-OP/HB-OP is Grade 1 to ANSI A156.3-2001. Where the spec allows Grade 2, the Cal-Royal 5500 is a 48 inch wide stile rim exit device with a push bar, Grade 2, heavy duty, non-fire-rated and not wood door compatible; the Cal-Royal A9820 Series is also a 48 inch exit only rim device catalogued at Grade 2 heavy duty. Both are wide stile bodies, so they are for hollow metal rather than an aluminum narrow stile storefront.
22) I need electrified exit hardware with request to exit - how does the Falcon 1792NL-OP/HB-OP compare to the electrified rim devices?
The Falcon 1792NL-OP/HB-OP takes an optional RX request-to-exit switch, and electric latch retraction and electric dogging are both selectable when ordering, on a Grade 1 narrow stile body. Among the peers, the SDC S6136 Spectra S6000 Series is an electrified architectural rim exit device at 36 inches with a 4 inch wide stile for 1-3/4 inch to 2 inch doors, and the Sargent 12-8810-LTRIM is a fire rated Grade 1 wide stile rim device with RX and MELR. The Securitron EMB is an electromechanical exit bar for 2-1/4 inch doors. The Falcon is the narrow stile option in that group.
23) What 48 inch rim exit device alternatives are there to the Falcon 1792NL-OP/HB-OP if the trim function does not matter?
For a plain exit only device at 48 inches, the Dexter ED1000 Series 4FT is a Grade 1 rim exit device, non-fire-rated and not wood door compatible; the CRL Jackson 1095 Series is a 48 inch wide stile crossbar rim panic device, exit only; and the Sargent 2828 is a Grade 1 reversible wide stile rim exit device for a 48 inch minimum door width. The Falcon 1792NL-OP/HB-OP differs in carrying the night latch / hold back cylinder function and a narrow stile body for aluminum storefront doors.
24) Is a concealed vertical rod device an alternative to the Falcon 1792NL-OP/HB-OP rim device?
They solve different openings. The Falcon 1792NL-OP/HB-OP is a rim device, latching into a surface strike - the TD35 strike ships with it. The Hager 4601 Series is a Grade 1 narrow stile concealed vertical rod exit device at 36 inches, and the Hager 4501 Series is the Grade 1 wide stile pushpad concealed vertical rod version, also 36 inches. Vertical rod devices latch top and bottom into the frame and sill, which suits pairs of doors without a mullion; a rim device needs a strike on the frame or mullion.
25) For standardizing narrow stile exit hardware across a campus, what Grade 1 narrow stile rim devices sit alongside the Falcon 1792NL-OP/HB-OP?
The Grade 1 narrow stile rim devices in the comparable field are the Detex 40 Advantex Series, rated extra heavy duty and not wood door compatible; the TownSteel ED3700 and ED8900 Series, both Grade 1 heavy duty at 36 inches; the Corbin Russwin ED4200 at 36 inches for 1-3/4 inch doors; the Adams Rite EX88 interlocking device; and the Stanley Security QED200 Series, Grade 1 heavy duty narrow stile with hex-key dogging. The Falcon 1792NL-OP/HB-OP is the 48 inch member of that group, non-handed and carrying ANSI A156.3-2001, with the night latch / hold back cylinder function.
