If you manage a commercial building in Brevard County, you’ve likely encountered a Dor-O-Matic push bar exit device. These are standard on high-traffic doors throughout offices, schools, and retail locations across Melbourne and the surrounding area. But when your staff can’t easily dog out the door — or when it won’t stay dogged — it’s time to investigate what’s really going on inside that hardware.
Understanding Dor-O-Matic Dogging Systems
A dogging kit allows a commercial door to remain in an unlocked, push-through state without activating the latch mechanism. This is essential during busy hours, deliveries, or emergency situations. The critical component that makes this work is the allen key strip — a precision channel inside the push bar that accepts a hex wrench. When you insert and turn the wrench, it retracts the latch. Turn it back and the latch re-engages.
The problem? This strip takes direct impact every single time someone dogs or un-dogs the door. In a busy commercial setting, that’s dozens of times daily.
Warning Signs Your Dogging Kit Is Wearing Out
A degraded allen key strip typically shows itself through specific symptoms. The hex key may require excessive force to turn, or it might spin freely without catching at all. Some doors lose tension and pop back into locked position on their own. Others become difficult to un-dog because the worn strip binds instead of releasing smoothly.
Visible corrosion is another red flag, especially on exterior doors exposed to Florida’s humidity. Left unchecked, forcing a worn strip damages the internal cam assembly, which transforms a simple component replacement into a costly full-kit repair.
Why Early Service Matters
Procrastinating on dogging kit repairs creates operational headaches. Staff adapt by using excessive force on the hex key, which accelerates damage and frustration. The Dor-O-Matic PBX-16 dogging kit (or your specific series equivalent) is relatively affordable when replaced early. Waiting until the door becomes completely non-functional means larger repair expenses and potential downtime.
Proper replacement involves removing the push bar end cap and carefully seating the new strip into the cam housing. Tolerances are tight — installation errors prevent the dogging function from engaging correctly. Most professionals recommend inspecting the cam and spring components simultaneously, since worn strips often indicate stress on those parts too.
