Adams Rite 3911-36 – Frequently Asked Questions

1) Will the Adams Rite 3900 exit device fit a narrow stile aluminum storefront door?
The 3900 Series needs a 3-3/4 inch stile to mount. Adams Rite builds it for narrow stile aluminum door construction, so a typical storefront stile will take it, but measure the stile face before ordering: anything under 3-3/4 inches rules it out. Door thickness is 1-3/4 inches standard.
2) What size opening will the Adams Rite 3900 concealed vertical rod device cover?
Single doors up to 4'0" x 9'0" and pairs up to 8'0" x 9'0". Device lengths run 30, 36, 42 and 48 inches, so pick the bar length against your door width, not the opening height.
3) Does the Adams Rite 3900 latch at both the header and the threshold?
No, it is single point latching in the header only. There is no bottom latch to align or a floor strike to cut, which makes it a cleaner install on thresholds and saves the usual bottom rod service calls. If your spec calls for top and bottom latching, this is the wrong device.
4) Can the Adams Rite 3900 be electrified for access control?
Yes, three ways. You can order it with EL electric latch retraction, MLR motorized latch retraction, or an alarm. Door position and latch status can be reported with a single or dual monitoring switch. Adams Rite also lists it as compatible with the 7800 Series electric strike if you are releasing at the frame instead.
5) What is the closest fire-rated alternative to the Adams Rite 3900 concealed vertical rod exit device?
The Sargent 12-MD8613 is the closest fire-rated peer: it is a Grade 1 concealed vertical rod device carrying a fire rating, built for wide stile doors, and supplied in a classroom function. The Adams Rite 3900 is also Grade 1 with a fire rating, carries a 3-3/4 inch stile width, and can be ordered with EL electric latch retraction or MLR motorized latch retraction plus single or dual monitoring switches. If the opening needs classroom-function keyed control from the outside, the Sargent is the direct answer; if it needs electrified retraction or latch monitoring, the 3900 covers it.
6) Which concealed vertical rod exit devices should I avoid if my opening is in a fire-rated assembly?
Several Grade 1 concealed vertical rod devices are specified as non-fire-rated and cannot go into a fire-rated assembly: the Von Duprin 3347A-3ft, the Von Duprin 5547-3ft crossbar, the Von Duprin 7547-3ft, the DORMA 9100 wide stile pushpad, and the DORMA 9600BB narrow stile pushpad are all listed with fire rating: No. The Adams Rite 3900 carries a fire rating, so it is the one of this group that suits a rated opening.
7) I need a concealed vertical rod device for a narrow stile aluminum door - is the Adams Rite 3900 the right pick or is there a better match?
The Adams Rite 3900 is catalogued with a wide stile type and a 3-3/4 inch stile width. For a true narrow stile leaf, the narrow stile peers are the Corbin Russwin ED4800 and ED7800 (both Grade 1, 1-3/4 inch door thickness, exit only accepting trim, the ED7800 with a crossbar), the DORMA 9600BB narrow stile pushpad, the Falcon 1690EO, 1990EO and 24-C exit only devices, and the Von Duprin 3347A, 5547 and 7547. Confirm your measured stile before committing either way.
8) Which concealed vertical rod exit device can be electrified for access control?
The Adams Rite 3900 can be ordered with EL electric latch retraction, MLR motorized latch retraction or an alarm option, plus single or dual monitoring switches, and it works with the 7800 Series electric strike. Among the peers, the concealed vertical rod devices from Corbin Russwin, Falcon, Von Duprin, DORMA, BEST Precision and CRL Jackson listed here are specified as mechanical exit only, dummy or keyed-function devices, so the 3900 is the one to spec when latch retraction and switch monitoring need to be part of the device.
9) Do I have to order the Adams Rite 3900 handed?
Handing is field reversible on the 3900, so one device covers left and right hand openings. Useful if you are stocking spares across a building instead of ordering per door.
10) What finishes does the Adams Rite 3900 exit device come in to match my existing storefront?
Seven: 313 dark bronze anodized, 335 black anodized, 628 clear anodized, 605 bright brass, 606 satin brass, 629 bright stainless and 630 satin stainless. The anodized options are the ones that normally match aluminum storefront framing; brass and stainless are for matching other door hardware. Touchbar is stainless steel and the device body is aluminum.
11) Does the Adams Rite 3900 accept lever trim for outside access?
Yes, multiple trim options and levers are offered. The device is configured for rim (8300/8400) and top of door mounted (8800/8700/EX88) setups, so match the trim to the configuration you are ordering rather than assuming any lever fits.
12) Which concealed vertical rod exit devices are intended for wood doors?
The BEST Precision 2701 is a wide stile reversible concealed vertical rod device for wood doors. The Von Duprin 7547 is specified as not wood door compatible, so it should not be substituted onto a wood leaf. The Adams Rite 3900 is built on aluminum construction with a 3-3/4 inch stile width and single-point latching in the header; verify the leaf material against your door schedule before ordering.
13) Which wide stile concealed vertical rod exit devices are alternatives to the Adams Rite 3900?
Among wide stile concealed vertical rod peers: the Corbin Russwin ED5800 is Grade 1, exit only accepting trim, for 1-3/4 inch doors; the DORMA 9100 is a Grade 1 heavy duty pushpad covering 1-3/4 to 2-1/4 inch doors; the BEST Precision 2701 is wide stile and reversible for wood doors, with the 2801 also wide stile; the CRL Jackson 1085 is a 48 inch non-handed wide stile exit only device. The Adams Rite 3900 is the wide stile Grade 1 option with a fire rating, offered in 30, 36, 42 and 48 inch sizes.
14) What looks like a substitute for a concealed vertical rod exit device but will not actually latch the door?
The Falcon 1491DT is a dummy trim narrow stile concealed vertical rod device supplied with a 9970 pull in a 42 inch length - its function is dummy, so it provides the matching appearance and pull but no latching or egress mechanism. It is used on the inactive leaf or for aesthetic match, not as a replacement for the Adams Rite 3900, which is a Grade 1 fire-rated latching device.
15) If I do not need outside trim or keyed entry, is there a simpler concealed vertical rod device than the Adams Rite 3900?
Yes. Exit only devices skip outside trim entirely: the BEST Precision 2601 is exit only, narrow stile and non-handed; the CRL Jackson 1085 and 1285 are both exit only, the 1285 as a push pad suiting narrow, medium or wide stile; the Falcon 1690EO, 1990EO and 24-C are Grade 1 exit only for 1-3/4 inch doors; the Von Duprin 3347A-EO is exit only less bottom rod. The Adams Rite 3900 is the choice when you want trim, lever options, electrified latch retraction or a fire rating on the same opening.
16) Is there a non-handed concealed vertical rod exit device, or do I have to specify handing?
The Adams Rite 3900 is field-reversible for handing, so one device covers either swing. Among peers, the BEST Precision 2601 is non-handed exit only narrow stile, the CRL Jackson 1085 is a 48 inch non-handed device, the BEST Precision 2701 is reversible, and the Von Duprin 3347A-EO is supplied exit only less bottom rod. That lets a property manager stock one device across a run of doors instead of splitting inventory by hand.
17) I need a concealed vertical rod exit device for a metal door on a 36 by 84 opening - what should I look at?
The Sargent MD8613F-LTRIM is the peer built for metal doors at 36 by 84 inches, Grade 1 heavy duty with hex dogging and lever trim. The Adams Rite 3900 is Grade 1 with a fire rating, 3-3/4 inch stile width, and comes in 30, 36, 42 and 48 inch device lengths with multiple trim and lever options. Note that hex dogging is generally not used on fire-rated assemblies, so match the device to whether your opening is rated.
18) What mounting height should the push bar be set at on an Adams Rite 3900?
Between 30 and 44 inches above the finished floor. That range is what keeps the touchbar within reach for accessible egress. Fasteners are machine screws into the prepared door.
19) Is the Adams Rite 3900 suitable for a high traffic school or hospital corridor?
It is a commercial device carrying ANSI/BHMA A156.3 Grade 1, the highest performance grade, with a stainless touchbar and single motion panic proof egress. Adams Rite lists educational and healthcare facilities among its applications, along with office, retail, industrial, multi tenant residential and government buildings.
