Adams Rite EX88-R628 – Frequently Asked Questions

1) Can I get the Adams Rite EX88 with a door position or latch monitoring switch?
Yes, monitoring is an ordering option rather than a field add-on. Each length and finish combination is offered with the monitoring switch or without it, so if you're tying the opening into an access control or alarm panel, pick the switch version up front.
2) What makes an interlocking rim device different from a standard rim panic device?
A conventional rim device throws a latch into a surface strike on the frame. The EX88 uses an interlocking bolt that ties the door to the frame, which resists jamb spreading, a common attack on aluminum storefront pairs where a frame can be pried apart enough to release a standard latch. If you've had break-ins by spreading the frame, that's the reason to choose this over a plain rim latch.
3) Will the EX88 work with an electric strike for card access?
It's built to pair with the Adams Rite 7800 Series electric strike, and electric latch retraction is available on the device itself. For a card reader entry you can either release at the strike or retract the latch electrically at the bar; latch retraction is the usual choice when you want the door free for scheduled unlock periods.
4) What is the closest narrow stile rim exit device to the Adams Rite EX88 from another manufacturer?
For a narrow stile aluminum opening, the closest Grade 1 narrow stile rim devices are the Corbin Russwin ED4200, a Grade 1 narrow stile rim device in 36 inch listed for 1-3/4 inch doors, the Falcon 19-R exit only Grade 1 narrow stile rim device in 36 inch for 1-3/4 inch doors, and the TownSteel ED3700 and ED8900, both Grade 1 heavy duty narrow stile rim devices in 36 inch. The EX88 differs from all of them in its interlocking bolt design, which locks the door to the frame to resist jamb spreading, and it is built for door thicknesses from 1-3/4 inch up to 2-3/4 inch.
5) I need a fire rated rim exit device, not the Adams Rite EX88 - what should I order?
The EX88 is carried with a fire rating value of No, so for a labeled fire door opening go to a device catalogued as fire rated: the Dexter ED1000-R-F-EO is a Grade 1 fire rated rim exit device, the Marks USA M9900F comes in 36 inch and 48 inch fire rated exit only versions with a panic protector end cap, the Arrow FS1250 is a fire rated 32 inch rim device, and the Orca OED85 is a 36 inch fire rated rim exit device. Note that fire rated devices are supplied without dogging, so confirm the opening does not need a held-open push bar.
6) My door is a wide stile aluminum or hollow metal door - is the Adams Rite EX88 still the right device?
The EX88 is built for narrow stile aluminum doors with a 2-1/2 inch stile. On a wide stile door, a wide stile chassis gives you more mounting surface and a wider pushpad: the Corbin Russwin ED5200 is a Grade 1 wide stile rim device in 36 inch, the Von Duprin 22-3FT is a 36 inch non-handed Grade 1 wide stile pushpad rim device for 1-3/4 inch doors, the Detex 10 Advantex is a 36 inch extra heavy duty Grade 1 wide stile rim device, and the TownSteel ED1100 is a 36 inch Grade 1 heavy duty wide stile rim device.
7) Can I use an SDC switch bar or pressure sense bar in place of the Adams Rite EX88 on an access controlled door?
Not as a direct swap. The EX88 is a mechanical Grade 1 rim exit device with its own interlocking latch bolt, available with electric latch retraction and compatible with the 7800 electric strike. The SDC MSB550 is a 36 inch mechanical switch bar and the SDC PSB560 SureExit is a 36 inch pressure sense bar with tri-failsafe technology; both are catalogued for narrow or wide stile but they release a separate electromagnetic lock rather than carrying a latch themselves. If the door has no maglock, you need a latching device like the EX88.
8) My storefront door is thicker than 1-3/4 inch - which exit devices will actually fit?
The Adams Rite EX88 covers 1-3/4 inch standard up to 2-3/4 inch, which is the widest thickness window among comparable rim devices. Most peers are listed for 1-3/4 inch only, including the Corbin Russwin ED4200 narrow stile and the Falcon 19-R. The DORMA 9300A covers 1-3/4 inch to 2-1/4 inch but is a wide stile device, and the Securitron EMB exit bar is listed at 2-1/4 inch. For a thick narrow stile aluminum leaf, the EX88 is the one that spans the range.
9) What lengths and finishes does the Adams Rite EX88 come in?
Three device lengths, 36, 42 and 48 inches, in three anodized finishes: 628 clear, 313 dark bronze and 335 black. Every length is offered in every one of those finishes, so you can standardize a building on one finish across mixed door widths.
10) Do I need to specify handing when ordering the EX88 panic device?
No. The EX88 is field reversible, so one device covers left and right hand openings and you can stock a single part number for a building with doors swinging both ways.
11) Can I add a lever or pull trim to the outside of an EX88 door?
Yes. Multiple trim options and levers are offered for the EX88, so the opening can be exit only or keyed from the pull side. Order the trim alongside the device, since the device itself covers the inside egress function only.
12) Is a crossbar exit device like the CRL Jackson 1095 an alternative to the Adams Rite EX88?
They are different operating styles. The EX88 uses a stainless steel touchbar/crossbar on a narrow stile aluminum door with a 2-1/2 inch stile. The CRL Jackson 1095 is a 48 inch crossbar rim panic device catalogued as wide stile exit only, and the Corbin Russwin ED3200 is a Grade 1 48 inch crossbar rim device, also wide stile, for 1-3/4 inch doors. If the frame is a narrow stile storefront, the wide stile crossbar chassis will not have the rail width to mount, so match the stile first and the bar style second.
13) What other narrow stile rim devices are Grade 1 heavy duty if I am standardizing a building on one series?
Grade 1 narrow stile rim devices in the same class as the Adams Rite EX88 include the Detex 40 Advantex, an extra heavy duty Grade 1 narrow stile rim device, the Stanley Security QED200 Grade 1 heavy duty narrow stile rim device with hex key dogging, the Dormakaba QED200 Grade 1 heavy duty narrow device in 36 inch, and the Falcon 1590EO and 1790EO Grade 1 narrow stile exit only devices in 42 inch for 1-3/4 inch doors. The EX88 is carried in 36, 42 and 48 inch with three anodized finishes, which helps if you are matching lengths across a run of storefront doors.
14) The Adams Rite EX88 is a rim device - what do I use if the opening needs a concealed vertical rod?
The EX88 latches to the frame at the rim with its interlocking bolt, so it will not serve an opening specified for top and bottom rod latching. For concealed vertical rod on a narrow stile door, the Hager 4601 is a Grade 1 concealed vertical rod narrow stile exit device in 36 inch; the Hager 4501 is the Grade 1 concealed vertical rod version with a wide stile pushpad in 36 inch. Vertical rod devices require the door to be prepped for concealed rods, so confirm the leaf before substituting.
15) Is a Cal-Royal 5000 or 5500 an equivalent swap for the Adams Rite EX88?
They are not the same class. The Adams Rite EX88 carries an ANSI/BHMA Grade 1 rating for narrow stile aluminum doors. The Cal-Royal 5000 is a 36 inch wide rim device with a touch bar and the Cal-Royal 5500 is a 48 inch wide rim device with a push bar, both carried as Grade 2 heavy duty. If the spec on the drawing calls for Grade 1 on a narrow stile opening, stay with the EX88 or another Grade 1 narrow stile device such as the TownSteel ED3700.
16) I need night latch or keyed trim function rather than exit only - what pairs with or replaces the Adams Rite EX88?
The EX88 is offered with multiple trim options and levers, so outside trim can be added to the same device. If you want a device catalogued with that function from the start, the Sargent 8504 is a Grade 1 narrow stile rim device in night latch function, and the Detex V4003A/03AN is a Grade 1 wide stile rim device supplied with night latch trim. The Corbin Russwin ED4200 is a Grade 1 narrow stile device listed as exit only or accepts trim.
17) What is the EX88 touchbar made of, and what fasteners does it install with?
The touchbar is stainless steel on an extruded aluminum device body, which is what you want on a high traffic entrance that gets pushed thousands of times a month. It mounts with machine screws, so plan the door prep for tapped holes rather than self-drillers.
18) Are any of these exit devices rated for wood doors instead of aluminum?
The Adams Rite EX88 is an aluminum substrate device engineered for narrow stile aluminum openings. Across the comparable rim devices - including the Corbin Russwin ED4200, Falcon 19-R, TownSteel ED3700, Von Duprin 22-3FT and Dexter ED1000 - wood door compatibility is carried as No. For a wood leaf, ask before ordering rather than assuming any of these will suit.
