Ensuring a building is safe for occupants involves more than just locking the doors at night. It requires providing a safe, reliable means of egress during an emergency. One of the most effective solutions for high-traffic or high-security doors is the vertical rod exit device.
These mechanisms, often found on double doors in commercial buildings, schools, and hospitals, offer superior security compared to standard rim devices because they latch at the top and bottom of the door frame. However, their reliability depends entirely on proper installation. A misaligned rod or a loose latch can turn a safety device into a safety hazard.
This guide walks you through the essentials of installing a surface vertical rod (SVR) exit device, specifically focusing on the specifications found in high-quality hardware like the Keyman X8 series.
A vertical rod exit device is a type of panic hardware that utilizes rods extending from a central push pad to latch points at the top and bottom of the door. Unlike a standard lock that latches only at the side, these devices provide multi-point security.
Specifically, models like the Keyman X801-A feature a three-point latching system. This means the door is secured at the top jamb, the floor, and the center edge. This design prevents the door from being pried open and ensures it stays closed against fire pressure, while still allowing immediate exit from the inside.
Before drilling a single hole, it is vital to understand the hardware you are working with. Commercial-grade devices must meet specific standards, such as ANSI/BHMA Grade 1 for durability and UL ratings for fire protection.
The following table outlines the typical specifications for a robust vertical rod exit device, based on the Keyman X8 series standards:
Component | Specification Details |
|---|---|
Door Dimensions | Standard fit for 3ft width x 7ft height (914mm x 2134mm) |
Top/Bottom Latch | Stainless Steel, Pullman type deadlocking latch with 5/8" (16mm) throw |
Center Latch | Stainless Steel, deadlocking with 3/4" (19mm) throw |
Rod Material | 1/2" Square tubing |
Rod Lengths (Standard) | Top: 35" (890mm) |
Fasteners | Machine screws/wood screws for surface mount; Sex bolts for through-hole mounting |
Fire Rating | UL Listed for 3-Hour fire rating |
Preparation is the most critical part of the process. If your measurements are off by even a fraction of an inch, the rods will not travel smoothly, and the latches will not engage.
Check Handing: First, determine if your door is left-hand or right-hand reverse. While many modern devices like the Keyman X8 are "non-handed" (meaning the trim is field reversible), you must orient the device correctly before mounting.
Apply the Template: Manufacturers provide a paper template. Tape this to the door at the specified height—usually 40 to 42 inches from the finished floor to the centerline of the device.
Mark and Drill: Use a center punch to mark the holes for the center case (the main push pad mechanism), the top latch, and the bottom latch. Drill the holes according to the instructions. If you are using sex bolts (recommended for high-traffic areas), you will need to drill all the way through the door.
Once the door is prepped, you can begin mounting the hardware.
Mount the main chassis (center case) to the door using the screws provided. Do not fully tighten them yet; leave a little room for adjustment. Ensure the device is level. If your device has a center latch, ensure it aligns with the strike plate on the door frame.
Install the top and bottom latch cases. For the Keyman X801-A, these are Pullman-type latches.
Top Latch: Mounts at the very top edge of the door.
Bottom Latch: Mounts at the bottom edge.
Ensure the bolts are facing the correct direction to engage with the strikes.

This is where precision matters. You will connect the 1/2" square tubing rods to the center case and the latch cases.
Top Rod: Connects the center chassis to the top latch. The standard length is typically around 35 inches for a 7-foot door.
Bottom Rod: Connects the chassis to the bottom latch.
Adjustment: Most rods have threaded ends or adjustment pins. You need to adjust the length so that when the push bar is depressed, the latch bolts retract fully (allowing the door to open). When the bar is released, the bolts must extend fully (locking the door).

Midway between the center case and the top/bottom latches, install the rod guides. These keep the rods from bending or rattling. They should be snug but shouldn't restrict the vertical movement of the rods.
Install the top strike on the door frame header and the bottom strike on the floor (or threshold).
Top Strike: Must align perfectly with the top latch bolt.
Bottom Strike: Often requires drilling into the concrete or threshold. Ensure it is clear of debris so the bolt can drop in freely.

Tighten all screws. Push the bar. The door should open smoothly. Release the bar and close the door. It should latch securely at all three points (top, bottom, and center).
The standard rods provided with most exit devices, including the X8 series, accommodate a 7-foot (2134mm) door. For taller doors (e.g., 8-foot or 10-foot), you typically need to purchase extension rods separately.
A surface vertical rod exit device (like the one described here) has rods visible on the face of the door. A concealed vertical rod device has rods hidden inside the hollow door. Surface rods are easier to install and maintain, while concealed rods are more aesthetically pleasing but require more complex preparation.
If the bottom rod drags, the adjustment is incorrect. You need to shorten the rod length slightly using the adjustment pin or threads so that the bolt retracts completely when the bar is pushed. Conversely, if it's too short, the door won't lock securely.
Installing a vertical rod exit device is a significant responsibility. These devices are life-safety hardware designed to facilitate escape during fires or emergencies. Always verify that your installation complies with local building codes and ADA requirements.
Using high-quality, certified hardware like the ANSI Grade 1 Keyman X8 series ensures that the device can withstand years of abuse while functioning perfectly when it matters most. If you are unsure about any step of the process, consult a professional locksmith or security integrator.
