Detex 20-695-36x84 – Frequently Asked Questions

1) Will a Detex 20/21 vertical rod device work on a pair of doors with no center mullion?
That is exactly what the 20/21 Advantex surface vertical rod device is for. It latches at the head and at the threshold instead of into a strike on the jamb, so a pair of doors can be secured without a removable mullion. If you want both leaves to operate that way, order a device for each leaf and specify the handing of each.
2) What is the difference between the top and bottom rod version and the top rod only version of the Detex 20/21?
Top and bottom rod devices latch into a strike at the head and drop a bolt into a dust proof strike in the floor. Top rod only devices, often called less bottom rod, latch at the head only, which keeps the bolt and floor strike out of the doorway where snow, debris, or wet cleaning would jam it. Both are orderable configurations of the 20/21.
3) Is the Detex 20/21 Advantex a wide stile or narrow stile exit device?
Wide stile. The 20/21 mounts on hollow metal and wood doors with a wide stile face; it is not intended for a narrow stile aluminum storefront door. For a narrow aluminum door you need a narrow stile device instead.
4) What door heights does the Detex 20/21 vertical rod exit device cover, and do I need special rods for a tall door?
Rod length is set by the door height you order: 84 inch, 96 inch, and 120 inch are all available. Order the device to match the actual leaf height rather than trying to stretch a standard 84 inch device up a 10 foot door. Device width is ordered as 36 inch or 48 inch to suit the door width.
5) Can the Detex 20/21 alarm or signal when someone pushes out the door?
Yes, and you choose the electronics when you order. Options are EA hardwired electric alarm, EB electric alarm with battery, EX request to exit signal switch for tying into an access control panel, and EE delayed egress. Order None if you want a purely mechanical device. EB suits an exterior door with no power run to it; EX is the one integrators want when the door is monitored.
6) Does the Detex 20/21 come with outside trim or a lever to get back in?
No. The 20/21 as configured here is exit only, a device only with no outside trim, so the door is not openable from the outside. If you need re-entry you will have to add outside trim or a key cylinder as a separate item.
7) I need a fire rated vertical rod device for a 36 x 84 door - what are my options besides the Detex 20/21?
The Detex 20/21 can be ordered fire rated, and also in hurricane and hurricane-plus-fire-rated configurations. If you want a fire rated device built specifically for a 36 x 84 opening, the Delaney F9100 Series (DLY-694300) is a Grade 1 fire rated heavy duty vertical rod device for a 36 x 84 door in an aluminum finish, and the Marks USA M9900FVR is a fire rated exit-only vertical rod device for 36 x 84, non-handed. The Detex remains the choice if you also need hurricane rating or a taller door height.
8) Do any vertical rod alternatives to the Detex 20/21 avoid having to specify handing?
Yes. The Marks USA M9900VR is a non-handed vertical rod panic exit device for 36 x 84, and the fire rated M9900FVR is likewise non-handed. The Detex 20/21 is a handed device and is ordered as Right Hand Reverse or Left Hand Reverse, though it is field-reversible, so one device can be flipped on site.
9) What is the closest Grade 1 wide stile surface vertical rod alternative to the Detex 20/21 Advantex exit device?
The Von Duprin 8827-3FT is the nearest match in configuration: a Grade 1 wide stile surface vertical rod exit device in a 3 ft size, prepped for 1-3/4 inch doors. The Detex 20/21 is also Grade 1 and wide stile, and it covers 36 inch and 48 inch device sizes with door heights of 84, 96 and 120 inches. If the opening is a standard 1-3/4 inch, 36 inch leaf, the two are directly comparable; for a 96 or 120 inch tall door, stay with the 20/21.
10) Which vertical rod devices look like substitutes for the Detex 20/21 but will not work on a fire rated opening?
Several peers in the same form factor are not fire rated: the Cal-Royal 9860 (Grade 2), the Delaney 9100 Series DLY-692301 and 8100 Series DLY-8100-3684 (both Grade 1), the Imperial USA ED-VR531 500 Series wide stile device (Grade 1), the Von Duprin 8827-3FT (Grade 1 wide stile), and the Marks USA M9900VR. Any of these can be mistaken for a drop-in on a labeled door. The Detex 20/21 can be specified fire rated, so if the leaf carries a label, order the fire rated configuration rather than substituting a non-rated device.
11) What dogging options are there on the Detex 20/21, and which should I pick for a retail door held open during business hours?
Three choices: 1/8 turn hex dogging, cylinder dogging, or less/no dogging. Hex is fine where only staff with the key wrench touch it. Cylinder dogging is the better pick for retail or a tenant space, since it dogs with a keyed cylinder you can put on the building keyway. Order no dogging on fire rated openings.
12) Is the Detex 20/21 Grade 1, and how does it compare to other vertical rod devices?
The 20/21 Advantex is Grade 1 and built as super heavy duty for high-abuse traffic. Among comparable surface vertical rod devices, the Von Duprin 8827-3FT is also Grade 1 wide stile, and the Delaney 9100 and 8100 Series are Grade 1 as well. The Cal-Royal 9860 is Grade 2 heavy duty, so it is a step down in rating if you are specifying Grade 1 for a school or hospital.
13) Do I need a paper template to install the Detex 20/21, and where do I get the door prep?
No paper template. The 20/21 ships with a patented mounting plate and strike locator system that marks the hole locations on the door and frame directly, which is what keeps the top strike and the floor strike in line. Detex publishes the installation instructions and parts list as PDFs if you want the prep dimensions in front of you before the crew shows up.
14) Is the bottom bolt on the Detex 20/21 a trip hazard for ADA compliance?
The bottom bolt assembly uses an ADA ramped bottom bolt cover, and the device operation is ADA compliant. If your facility would rather have nothing at the threshold at all, order the top rod only configuration so there is no bottom bolt or floor strike in the opening.
15) Can the Detex 20/21 be used on a hurricane rated opening?
Yes. Hurricane is an orderable rating option on the 20/21, and there is a combined Hurricane and Fire Rated option for openings that need both. If the opening is only a normal egress door, the Non-Rated build is the one to order.
16) Is there a lighter duty or lower grade vertical rod exit device if Grade 1 is not required?
The Cal-Royal 9860 is a heavy duty, Grade 2, non-fire-rated surface vertical rod exit device with ADA compliance and exit-only function. The Detex 20/21 Advantex is Grade 1 and commercial rated, with an ADA ramped bottom bolt cover. Choose the 9860 where the spec allows Grade 2; keep the 20/21 where the drawing calls for Grade 1 or where a fire or hurricane rating is required.
17) What should I use instead of the Detex 20/21 on a 48 inch wide leaf?
The Detex 20/21 itself is offered in a 48 inch size, so it covers that leaf directly. If you want an alternative built for that width, the Marks USA M9900VR-48X84 is a 48 x 84 exit-only vertical rod panic device, and the Marks USA M9900F-VR is the 48 x 84 fire rated exit-only version. Both are sized for an 84 inch door height, while the Detex also covers 96 and 120 inch heights.
18) Is there an alternative if I only need a top rod device rather than top and bottom rods?
The Detex 20/21 is configurable as either a top and bottom rod device or a top rod only device, so the change is made in how you specify it. The comparable vertical rod devices - including the Von Duprin 8827-3FT, Delaney 9100 Series DLY-692301, and Marks USA M9900VR - are catalogued as single vertical rod configurations without that choice, so if the opening calls for top latch only, specify the 20/21 top rod only build.
19) What finishes does the Detex 20/21 come in for matching other doors in a building?
Ten finishes, all applied over stainless steel with a PVD coating: 605 polished brass, 606 brushed brass, 611 polished bronze, 612 brushed bronze, 613 oil rubbed bronze, 628 brushed aluminum, 629 polished stainless, 630 brushed stainless, 693 black painted, and 695 dark bronze painted. For a fleet of commercial openings, 630 and 628 are the usual standards to match existing hardware.
