Detex V51xNS HD 628 96 36X84 – Frequently Asked Questions

1) Will the Detex V51xNS work on a pair of aluminum storefront doors with no mullion?
That is exactly what the V51xNS is built for. It is a narrow stile surface vertical rod device for double doors without a mullion, so the top latch bolt engages a strike at the head rather than a center mullion. The narrow stile designation means it fits the slim vertical rail on aluminum storefront and glass front doors, where a wide stile device like the Von Duprin 8827 or the Imperial USA ED-VR531 will not mount.
2) Is the Detex V51xNS top rod only, and does that mean the bottom of the door is unsecured?
Top rod only, yes. The V51xNS latches at the head with a 3/4 inch stainless steel deadlocking top latch bolt and there is no bottom rod or floor strike. That keeps the bottom of the opening clear of rods and floor hardware, which is why it is a common choice on storefront pairs, but the leaf is held only at the head. If your spec calls for two-point latching top and bottom, this is not the device.
3) Do I have to specify handing on the Detex V51xNS narrow stile exit device?
Yes, handing is a required choice: Right Hand Reverse or Left Hand Reverse. The device is handed but field reversible, so if the wrong hand arrives on site it can be converted without ordering extra parts. Exit devices on outswinging doors are always reverse-bevel hands, which is why only RHR and LHR are offered.
4) Can I get the Detex V51xNS fire rated for a stairwell pair?
Rating is a required selection: Standard or F for fire rated. Pick the F option for a labeled opening. Note that fire rated exit devices cannot be dogged, so a fire rated order should be specified Less Dogging rather than cylinder or hex dogging.
5) Can the Detex V51xNS be used as entry hardware, or is it exit only?
Either. Outside trim is one of the ordering choices, so the same device can be exit only or set up for outside entry. The options are 01PN blank plate narrow, 03AN night latch pull trim narrow, 03PN night latch trim narrow, 08BN classroom lever trim, 09BN storeroom lever trim, or Exit Only with no outside trim at all. For a tenant entry you want 09BN storeroom (key retracts the latch each time) or 08BN classroom; for after-hours key access on a storefront, a night latch trim is the usual pick.
6) Does the Detex V51xNS come with a local alarm or delayed egress option?
Yes, and the electrified option is a required selection when ordering. Choices are None, EB battery powered electric alarm, EA hardwired electric alarm, or EE delayed egress. EB is the simple retrofit for a propped-door problem with no wiring to run. EE delayed egress is the one to specify where the authority having jurisdiction permits a timed hold on egress, and it needs power run to the door.
7) What is a wide stile alternative to the Detex V51xNS surface vertical rod exit device?
The Detex V51xNS is built for narrow stile doors, so on an aluminum or hollow metal door with a wide stile the Von Duprin 8827-3FT is the device to look at instead. It is a Grade 1 wide stile surface vertical rod device in a 3 ft width, prepped for 1-3/4 inch door thickness. The Imperial USA ED-VR531 from the ED-500 Series is another Grade 1 wide stile surface vertical rod device at 36 inches. Stile width is the deciding factor here: a wide stile rail will not fit the narrow vertical stile the V51xNS was designed around.
8) What fire rated vertical rod exit device can I use instead of the Detex V51xNS F option?
The V51xNS is ordered with a Rating choice of Standard or F - Fire Rated, so the fire rated version comes off the same platform. If you need a different fire rated surface vertical rod device, the Delaney F9100 Series (DLY-694300) is Grade 1 fire rated for a 36 x 84 inch door in an aluminum finish. Marks USA offers the M9900FVR at 36 x 84 inches, fire rated and non-handed, and the M9900F-VR at 48 x 84 inches, both exit only. Note the fire rated Marks and Delaney units above are exit only or fixed-size builds, while the Detex is configurable for trim and handing.
9) Which vertical rod exit devices cover a 48 inch wide door like the Detex V51xNS does?
The Detex V51xNS is offered in both 36 inch and 48 inch rail sizes, with door heights of 84, 96 and 120 inches. Among other surface vertical rod devices sized for wide leaves, the Marks USA M9900VR is available in a 48 x 84 inch build and the fire rated M9900F-VR also comes in 48 x 84 inches. Both of those are exit only and fixed to an 84 inch door height, so for a 96 or 120 inch tall opening the Detex configuration is the one that covers it.
10) What is the difference between cylinder dogging and hex dogging on the Detex V51xNS, and which should I order?
Both hold the pushbar depressed so the door pushes free during business hours, using a 1/8 turn dogging mechanism. Hex dogging is turned with an allen key, so anyone with the key can dog it. Cylinder dogging takes a keyed cylinder, which is what property managers and institutional buyers pick when only authorized staff should be able to dog the door. Less Dogging is the third choice and is the one to use on fire rated openings. Cylinder dogging requires a mortise cylinder, ordered separately.
11) Will the Detex V51xNS hold up in a school or hospital corridor?
It is rated Grade 1 heavy duty and built for commercial service, with a ribbed aluminum rail extrusion, impact resistant ABS, and anodized surfaces. Detex lists it for office buildings, schools, healthcare, retail, industrial, multi-tenant residential, and government facilities. It is not weatherized, so keep it on interior or protected openings rather than fully exposed exterior doors.
12) What is a good Grade 1 alternative to the Detex V51xNS if my doors are wide stile?
The V51xNS only suits narrow stile doors. For a wide stile leaf, the Von Duprin 8827-3FT is a Grade 1 wide stile surface vertical rod device for 3 ft doors and 1-3/4 inch thickness, and the Imperial USA ED-VR531 is a Grade 1 wide stile surface vertical rod in a 36 inch exit only configuration. Both are non-fire-rated in the specs we hold, so for a labeled wide stile opening look instead at the Delaney F9100 Series, which is Grade 1 fire rated for a 36 x 84 door.
13) Is the Cal-Royal 9860 a direct substitute for the Detex V51xNS?
They are not interchangeable on every opening. The Cal-Royal 9860 is a Grade 2 heavy duty surface vertical rod device, exit only, and is not fire rated. The Detex V51xNS is Grade 1 heavy-duty and is available in an F fire rated configuration, with outside trim options ranging from a blank plate to classroom and storeroom lever trim. If your spec calls out Grade 1 or a fire rated opening, or you need keyed outside trim, the 9860 will not cover it.
14) I only need exit only vertical rod hardware with no outside trim - what are my options besides the Detex V51xNS?
The V51xNS can be ordered Exit Only, but it is also offered with blank plate, night latch, classroom lever and storeroom lever trims, so it is a broader platform than you need for a pure push-to-exit opening. Dedicated exit only devices include the Marks USA M9900VR at 36 x 84 inches, non-handed, and the M9900VR 48 x 84 inch version for wider leaves. The Cal-Royal 9860 is also an exit only surface vertical rod device, rated Grade 2. The Imperial USA ED-VR531 is a Grade 1 exit only device as well.
15) What is a simpler Grade 1 vertical rod exit device for a standard 36 x 84 inch door?
The Detex V51xNS is a configurable platform - you pick handing, rating, dogging, finish, outside trim, rail size and door height, which is useful on a mixed building but more decisions than a single standard opening needs. For a fixed 36 x 84 inch door, the Delaney 8100 Series (DLY-8100-3684) is a Grade 1 vertical rod device built to that size, and the Delaney 9100 Series (DLY-692301) is a Grade 1 heavy duty vertical rod device for 36 x 84 inches in a stainless steel finish. Neither is fire rated, so keep the Detex F configuration or another fire rated unit for rated openings.
16) I need a non-handed vertical rod exit device - does the Detex V51xNS work or should I look elsewhere?
The Detex V51xNS is a handed device, ordered Right Hand Reverse or Left Hand Reverse, though it is field reversible. If you would rather stock a single non-handed unit, the Marks USA M9900VR at 36 x 84 inches is non-handed, as is the fire rated M9900FVR at 36 x 84 inches. Both are exit only, so they suit push-to-exit openings rather than ones needing outside lever or night latch trim.
17) What finishes does the Detex V51xNS come in, and will it match dark bronze or black storefront?
Two finishes: 628 brushed aluminum and 711 black aluminum. The 711 black is the one that blends with black anodized storefront framing. There is no dark bronze option, so on bronze framing you are choosing between the two anodized aluminum finishes.
18) How hard is the Detex V51xNS to install, and do I need a paper template?
No paper template. The V51xNS uses Detex's patented mounting plate and strike locator system, which sets the hole locations and strike position directly on the door and head. Detex publishes installation instructions and a parts list as PDFs, plus door prep templates and an install video, so a first-time installer has the door prep documented before cutting anything.
