Detex GB16 – Frequently Asked Questions

1) What is the Detex GB glass bead shim kit actually for?
It is a 1/4 inch mounting spacer that sits between a Detex exit device and a flush door that has light kit moldings or a glass bead standing proud of the door face. Without it, the device chassis bears on the molding instead of the door skin, which binds the touchbar and stresses the mounting. The kit ships as a shim plate with mounting hardware as applicable. It is a mounting accessory, not an exit device, so you still need the panic device itself.
2) Which Detex exit device series does the GB shim kit fit?
Across the kit models, coverage spans the Detex 10, 20, 21, 30, 40, 50, 51, 60, 70, 80 and V50 Series, but each individual kit is tied to specific series. GB1 covers 10, 70 and 80 Series Advantex; GB3 covers 20 Series Advantex; GB4 covers 21 Series Advantex; GB6 covers 51 Series Advantex; GB16 covers 30 Series Advantex; and GB2 covers 40 Series and 60 Series with the EC2 endcap. Pick the kit that matches the device already on the door, not just the brand.
3) I have a Detex 40 Series device, which GB glass bead kit do I order?
GB2 is the kit for 40 Series, and it also covers 60 Series devices fitted with the EC2 endcap. The endcap matters on the 60 Series side: the kit is called out for the EC2 endcap specifically, so confirm which endcap is on the device before you order.
4) Will the Detex GB shim kit work on a Von Duprin or Marks USA exit device?
No. The GB kits are built to the mounting pattern of Detex devices in the 10, 20, 21, 30, 40, 50, 51, 60, 70, 80 and V50 families. A Von Duprin 88 Series surface vertical rod device or a Marks USA M9900VR uses its own chassis and hole pattern, so a Detex shim will not line up. Source the shim from the same maker as the device on the door.
5) Can a Detex GB glass bead shim kit be used to mount a Von Duprin or Marks USA vertical rod device on a flush door with light kit molding?
The GB shim kits are Detex mounting spacers matched to Detex exit device series - 10, 20, 21, 30, 40, 50, 51, 60, 70, 80 and V50 Series depending on the kit model - so the kit selection follows the Detex device already on the door. The Von Duprin 8827-3FT is an 88 Series wide stile surface vertical rod device rated for a 1-3/4 inch door, and the Marks USA M9900VR is a 36 by 84 inch exit only vertical rod panic device; both are complete devices with their own mounting arrangements rather than Detex series hardware, so a molding offset on those openings is handled through that manufacturer's own mounting parts.
6) The door has a glass light kit and needs a fire rated vertical rod exit device - what should be specified?
A GB glass bead shim kit is a 1/4 inch mounting spacer that corrects for a protruding molding; it does not itself carry a fire rating, so the rating comes from the device chosen for the opening. Vertical rod devices carrying a fire rating include the Delaney F9100 Series, a Grade 1 fire rated heavy duty vertical rod device for a 36 by 84 inch door in aluminum finish, and the Marks USA M9900FVR, a fire rated exit only non-handed vertical rod device for a 36 by 84 inch door, with the MARM9900F-VR covering the 48 by 84 inch fire rated opening.
7) Do I need a glass bead shim kit on a door with a vision lite?
Only if the light kit molding or glass bead protrudes into the area where the exit device mounts. If the door face is flat under the whole footprint of the device and the rails, the device mounts directly and no shim is needed. Where the molding stands proud, the 1/4 inch shim restores a flat mounting plane and keeps the device from binding or sitting under stress.
8) Does the Detex GB shim kit come in different lengths for 8 ft and 10 ft doors?
Kits are configured for standard, 7 ft, 8 ft and 10 ft door heights. On a vertical rod device the shimming has to follow the rod runs the full height of the door, so the door height drives the kit as much as the device series does. Order by both: the series of your Detex device and the height of the opening.
9) I am replacing an exit device on a glass-bead door, should I shim or just swap the device?
If you are staying with a Detex device in a covered series, shimming is the cleaner route: the GB kit adds a 1/4 inch flat mounting plane over the molding and you keep the existing prep. If you are replacing the whole device anyway and the opening is a pair or a single needing top and bottom latching, ZenSupply carries surface vertical rod devices such as the Von Duprin 8827 in 3 ft wide stile, the Imperial USA ED-VR531 wide stile, and the Marks USA M9900VR at 36 x 84. A fire rated opening narrows that to the fire rated models, the Marks USA M9900FVR or the Delaney F9100 Series.
10) Is the GB kit an exit device or just the spacer?
Just the spacer. You get the shim plate and mounting hardware as applicable, sized to hold a 1/4 inch offset. The panic device, rods, strikes and trim are ordered separately. If you need the device itself, that is a surface vertical rod exit device such as the Marks USA M9900VR at 36 x 84, exit only and non-handed, or the 48 inch M9900VR for a wider leaf.
11) What is the difference between ordering a GB shim kit and ordering a complete surface vertical rod exit device?
The GB kit supplies the shim plate and mounting hardware that sets a Detex exit device 1/4 inch off a flush door face where a light kit molding protrudes - it adds no latching or egress function of its own. A complete surface vertical rod device is the egress hardware itself: the Imperial USA ED-VR531 is a Grade 1 wide stile 36 inch surface vertical rod device with an exit only function, and the Delaney 8100 Series is a Grade 1 vertical rod device sized for a 36 by 84 inch door. If the opening still needs the panic device, one of those is the line item; the shim is only ordered alongside a Detex device that is being mounted over a molding.
12) Which GB kit matches the Detex device, and how does that differ from picking a device by grade the way other brands are specified?
GB kits are selected by the Detex series they mount to: GB1 for 10, 70 and 80 Series Advantex, GB3 for 20 Series, GB4 for 21 Series, GB6 for 51 Series, GB16 for 30 Series, and GB2 for 40 Series and 60 Series with the EC2 endcap. That is a device-family match, not a performance rating. Grade is how a replacement device is specified instead - the Delaney 9100 Series is a Grade 1 heavy duty vertical rod device in stainless steel for a 36 by 84 inch door, while the Cal-Royal 9860 is a Grade 2 heavy duty surface vertical rod device with an exit only function.
13) Can I use a washer or a piece of stock instead of the Detex glass bead kit?
The kit exists because the offset has to be exactly 1/4 inch and it has to be continuous under the device, not just at the fastener points. Packing individual screws with washers leaves the chassis unsupported between them and puts the touchbar out of plane, which is the binding the kit is there to prevent. The kit gives a shim plate plus the hardware to suit.
