Marks USA M9900-48-32D – Frequently Asked Questions

1) Do I have to specify handing for the Marks USA M9900 panic bar?
No handing to specify. The M9900 is non-handed and works on left or right hand openings, single or double doors, which is why facilities buy one part number and stock it for a whole building.
2) Does the Marks M9900 rim device have an outside lever or is it push-to-exit only?
Exit only. There is no outside trim function on the M9900, so from the corridor or exterior side the door stays secure with no lever or cylinder operation. If the opening needs key or lever entry from outside, you want a device that accepts trim, such as the Corbin Russwin ED5200 or ED4200, both listed as exit only plus accepts trim.
3) Is the Marks USA M9900 a Grade 1 exit device and is it UL listed for panic hardware?
Both. The M9900 is built to ANSI 156.3 (2001), Grade 1 and is UL Listed for panic hardware. Grade 1 is the highest ANSI/BHMA operational grade, which is what most institutional and government specs call for on egress openings.
4) Will the Marks M9900 latch into the strike prep already in my frame?
In most cases yes. The M9900 uses a dead latch bolt with a 3/4 inch stainless steel throw and is built to retrofit popular door and frame preps, so it typically drops onto an opening where another rim device came off. Measure your existing rim strike location against the 3/4 inch throw before you pull the old device.
5) What is the closest cross-brand equivalent to the Marks USA M9900 48 inch rim exit device for a 48 inch opening?
For a 48 inch wide stile opening, the Cal-Royal A9820 is a 48 inch rim exit device in exit only function, and the DORMA 9300 Series is a 48 inch wide stile panic rim exit device, exit only, Grade 1 heavy duty with a 1-3/4 inch to 2-1/4 inch door thickness range. Corbin Russwin ED3200 is also a 48 inch Grade 1 wide stile rim device at 1-3/4 inch door thickness, though it uses a crossbar rather than a touchbar. The M9900 is Grade 1 under ANSI 156.3 (2001), UL Listed for panic hardware, exit only, in a 48 inch size for 1-3/4 inch doors.
6) My door is thicker than 1-3/4 inches. What rim exit device covers that?
The Marks USA M9900 is specified for 1-3/4 inch door thickness. For thicker leaves, the DORMA 9300 Series covers 1-3/4 inch to 2-1/4 inch and Adams Rite 8800 Series covers the same 1-3/4 inch to 2-1/4 inch range. SDC S6136 covers 1-3/4 inch to 2 inch, and the Securitron EMB electromechanical exit bar is listed at 2-1/4 inch.
7) Is the Marks USA M9900 the right device for a fire-rated opening, or is there a listed alternative?
For an opening that requires a fire-labeled exit device, Adams Rite 3700 Series is a fire-rated narrow stile rim exit device, Grade 1, and Dexter ED1000 is available as a Grade 1 fire-rated rim exit device. Arrow FS1250 is a fire-rated 32 inch rim device for 1-3/4 inch doors, and Orca OED85 is a fire-rated 36 inch rim device in exit only function. The M9900 is a Grade 1 device carrying a UL listing for panic hardware and a 3-hour fire-rated dead latch bolt with a stainless steel 3/4 inch throw.
8) I need the exit device to tie into access control. What replaces the M9900 on an electrified opening?
The Marks USA M9900 is a mechanical exit only device with hex key dogging. For electrified openings, SDC S6136 is a 36 inch electrified architectural rim exit device with a 4 inch wide stile for 1-3/4 inch to 2 inch doors, Securitron EMB is an electromechanical exit bar for 2-1/4 inch doors, and Dormakaba E2103 is a 36 inch electrified rim device with 4908A trim in classroom function. Sargent 12-8810-LTRIM is a fire rated wide stile rim device with RX and MELR.
9) My door is an aluminum storefront with a narrow stile. Can I use the M9900 or do I need a different device?
The Marks USA M9900 is a wide-bar device sized for a 48 inch door at 1-3/4 inch thickness. For narrow stile aluminum storefront, the narrow stile rim devices include Adams Rite 8800 Series with a 1-3/4 inch to 2-1/4 inch door thickness range, Adams Rite EX88 interlocking rim device, Falcon 1590EO at 42 inch for 1-3/4 inch doors, Falcon 19-R at 36 inch, Corbin Russwin ED4200 at 36 inch Grade 1, and TownSteel ED3700 and ED8900 at 36 inch Grade 1 heavy duty.
10) I need outside trim like a lever or nightlatch with the exit device. Does the M9900 take it, and what does?
The Marks USA M9900 is an exit only device, meaning no outside trim function. Corbin Russwin ED5200 is a 36 inch Grade 1 wide stile rim device whose function is exit only or accepts trim, and Corbin Russwin ED4200 in narrow stile is likewise exit only or accepts trim. Sargent 8504 is a narrow design rim exit device in nightlatch function, and Detex V4003A/03AN is a Grade 1 wide stile rim device with nightlatch trim. Dormakaba E2103 pairs a 36 inch electrified rim device with 4908A trim in classroom function.
11) Can I hold the M9900 exit device unlocked during business hours?
Yes, it uses hex key dogging. Insert the hex wrench at the touchbar and the latch is held retracted so the door push-pulls freely during high traffic, then dog it back out to relatch at close. Hex key dogging is mechanical, so it does not depend on power.
12) Should I use a rim exit device or a vertical rod device on my opening?
A rim device like the M9900 latches into a strike on the frame at the lock edge. That's the right choice for a single door, or for a pair with a center mullion. On a pair with no mullion, the rim device has nothing to latch into on the inactive leaf, and you want a vertical rod device instead, such as the Hager 4501 Series concealed vertical rod with wide stile pushpad or the narrow stile Hager 4601. Rim devices are simpler to install and to maintain, which is why they dominate single-door egress.
13) Will the Marks M9900 touchbar survive a hallway where carts hit the doors?
That is what the end cap is for. The M9900 carries a mitered steel flush-mounted Panic Protector end cap, the part that normally breaks first when a cart or a pallet jack clips the device, plus a heavy-gauge extrusion body over a cast chassis. The touchbar is also reduced-projection, so there is less of it sticking into the corridor to catch on equipment.
14) Can I standardize the Marks M9900 across every exit door in my school building?
Across the 48 inch metal leaves, yes, and that's the usual reason it gets specified for schools, universities and other institutional buildings. It's non-handed, so one part number covers left and right hand openings, and it retrofits popular preps, so it goes onto existing frames as devices wear out. Where the building has narrower leaves you order the matching width, and wood leaves need a different device entirely.
15) What is a lighter-duty alternative to the Marks USA M9900 for a low-traffic commercial door?
Cal-Royal 5000 is a 36 inch wide rim exit device with a touch bar on a Grade 2 chassis, and Cal-Royal 5500 is a 48 inch push bar device also Grade 2. Design Hardware 2000R is a 33 inch standard duty rim device with hex key dogging, and Hager 4701 is a 36 inch standard duty rim exit device. The Marks USA M9900 is built to ANSI 156.3 (2001) Grade 1 with a heavy-duty cast chassis for schools, universities and other institutional or commercial buildings.
16) I am standardizing exit devices across a campus. Which Grade 1 rim devices besides the Marks USA M9900 also use hex key dogging?
Design Hardware 1000R is a 33 inch heavy duty rim device with hex key dogging, and the Stanley Security QED200 is a Grade 1 heavy-duty narrow stile rim device with hex-key dogging; Dormakaba QED200 is the same series in a 36 inch Grade 1 heavy duty narrow device. The Marks USA M9900 uses hex key dogging and is non-handed, which lets one dogging key serve a mixed run of openings.
17) The M9900 is 48 inches. What is the equivalent Grade 1 rim device for a 36 inch door?
For a 36 inch leaf, Von Duprin 22 Series is a 36 inch non-handed Grade 1 wide stile pushpad rim device for 1-3/4 inch doors, TownSteel ED9700 is a 36 inch Grade 1 heavy duty wide stile device, Corbin Russwin ED2200 is a 36 inch Grade 1 wide stile rim device in exit only, and Dexter ED1000 comes in a 3FT Grade 1 rim device as well as a 4FT size that matches the M9900's 48 inch coverage. Detex 10 Advantex is a 36 inch wide stile extra heavy duty Grade 1 rim device.
18) What finishes does the Marks USA M9900 48 inch exit device come in?
Two finishes: US32D satin stainless steel and US10B oil-rubbed dark bronze. US32D is the usual match for institutional and school openings where the rest of the hardware is satin stainless; US10B is the one to pick when the building's door hardware is dark bronze.
