Emergency exits are the most critical safety feature in any commercial building. When an emergency strikes, the hardware on these doors must function flawlessly to allow safe, immediate egress. Among the various types of panic hardware available, the vertical rod exit device is a popular choice for double doors because it offers two points of latching—top and bottom—providing superior security without a center mullion.
However, installing these devices can be intimidating. Unlike standard rim devices that latch to the side frame, surface vertical rod (SVR) devices require precise alignment of rods, latches, and strikes at the very top and bottom of the door. If these components are slightly off, the door may not latch properly, compromising the building's fire rating and security.
This guide answers the most common questions regarding the installation process. whether you are a facility manager or a locksmith, we will walk you through how to properly install a surface vertical rod exit device, ensuring your building remains safe, secure, and code-compliant.
Before drilling any holes, you must ensure you have the right hardware for the specific door application. While many modern devices are versatile, checking the specifications against your door's reality is the first step to success.
Standard vertical rod exit devices come with rods designed for specific door heights. For example, the Keyman X801-V is designed for a standard 7-foot (2134mm) door. If your door is 8 feet or taller, you will likely need extension rods. Conversely, if your door is shorter, you will need to cut the rods to size (more on that later).
"Handing" refers to the direction the door swings. While some hardware is specific to "Right Hand Reverse" or "Left Hand Reverse," many high-quality units, such as the Keyman X801-V, are "non-handed." This means the device design allows for installation on either side without complex internal reconfiguration. However, you should always check the "Trim" (the handle or lever on the outside) as this is often field reversible but needs to be set correctly before mounting.
You cannot eyeball this installation. You will need the paper template provided by the manufacturer. Tape this template to the door to mark your drill points accurately. In terms of tools, ensure you have:
Power drill and bits (size determined by the fasteners)
Hacksaw (for cutting rods)
Level and tape measure
Phillips and flathead screwdrivers
Center punch

The center chassis is the heart of the vertical rod exit device. It houses the push bar mechanism and connects the top and bottom rods.
Mark the height: Standard installation height is usually 40 to 48 inches from the finished floor to the center of the push bar. Check local building codes for ADA compliance requirements in your area.
Apply the template: Align the template with your height mark and the edge of the door.
Drill holes: Mark the mounting holes with a center punch. If you are using machine screws, drill and tap the holes. If using sex bolts (common for fire-rated doors or heavy traffic areas), drill all the way through the door.
Mount the chassis: Secure the center case to the door. Do not tighten the screws 100% yet; leave a tiny bit of wiggle room for final alignment with the rods.
Unlike the center chassis, the latch mechanisms are mounted at the extreme top and bottom of the door.
Top Latch: This typically uses a Pullman-type latch. Align the template at the top of the door. Ensure the latch bolt faces the correct direction to engage with the strike.
Bottom Latch: Similarly, mount the bottom latch case near the floor. It is crucial to ensure there is enough clearance for the latch to retract fully so it doesn't drag on the floor when the door opens.
For devices like the Keyman X801-V, the top and bottom latch cases are compact (4-1/2" x 2-1/8"), designed to fit standard stile widths.
This is the step where most mistakes happen. The rods connect the center push bar to the latches. If they are too long, the door won't latch; too short, and the latches won't retract.
Measure the gap: With the center chassis and latch cases mounted, measure the distance between the connecting points.
Check the rod length: The X801-V comes with a 35" top rod and a 31-3/8" bottom rod.
Cut if necessary: If your door is shorter than the standard 7 feet, you will need to cut the rods. Mark the rod carefully, subtracting the length required for the threaded connectors or pins.
Install the rods: Slide the rods into the latch cases first, then connect them to the center chassis.
Adjust: Most rods have threaded ends for fine-tuning. Adjust them so that when the push bar is depressed, both top and bottom latches retract completely. When the bar is released, they should extend fully.
The strike is the metal plate that the latch engages with to keep the door closed.
Top Strike (e.g., X980-035): This is mounted to the door frame header. It usually includes a roller to help the latch slide smoothly into the locked position.
Bottom Strike (e.g., X980-178): This is mounted to the floor or the threshold. It can be a tripping hazard if not installed flush or if a specifically designed ADA threshold isn't used.
Pro Tip: Ensure the floor is clean and level before installing the bottom strike. If the floor is uneven, the bottom bolt may not line up correctly.
When selecting or installing a vertical rod exit device, you want to ensure it meets safety standards. High-traffic commercial environments require durability (ANSI Grade 1) and often fire resistance (UL ratings).
The following table outlines the specifications for a robust unit like the Keyman X801-V, which serves as a good benchmark for quality installation requirements.
Feature | Specification Details |
|---|---|
Fire Rating | UL Listed for 3-Hour fire rating (essential for fire doors) |
Durability Grade | ANSI/BHMA A156.3 Grade 1 (highest durability standard) |
Door Dimensions | Width: 3Ft (914mm) | Height: 7Ft (2134mm) |
Latch Throw | 5/8" (16mm) throw for top and bottom latches |
Rod Dimensions | 1/2" Square tubing (standard for stability) |
Backset | 2-7/16" (61.7mm) |
Accessibility | Complies with American Disability Act (ADA) |
An SVR device, like the one described in this guide, has rods that run visibly on the face of the door. A CVR device has rods hidden inside the hollow interior of the door. SVRs are easier to install and maintain because you can access the rods without taking the door off its hinges. CVRs are often chosen for aesthetics but are more labor-intensive to install.
Installing panic hardware on glass doors (especially narrow stile aluminum doors) requires specific devices designed for narrow stiles. While standard devices fit 3-foot wide doors, you must check the width of the vertical stile (the frame around the glass). The Keyman X801-V fits standard aluminum and hollow metal doors, but always verify the mounting plate width against your door stile.
Regular maintenance is vital. Every few months, check that the top and bottom latches are free of debris. The bottom latch, being near the floor, is prone to collecting dirt and dust, which can cause it to stick. Lubricate the internal mechanisms with a non-greasy lubricant (like graphite or silicone spray) annually to ensure the "panic" function works smoothly.
Installing a vertical rod exit device requires patience and precision, but the result is a secure, code-compliant opening that ensures the safety of everyone in the building. By carefully marking your templates, ensuring your rods are cut to the exact length, and verifying that your latches engage the strikes fully, you create a reliable emergency exit system.
If you are unsure about the fire rating requirements of your specific opening or need hardware that meets specific ANSI Grade 1 standards, it is always best to consult with a professional locksmith or hardware supplier. The safety of your building occupants depends on that door opening when it matters most.
