There is a moment on access control jobs that nearly every general contractor and security installer has experienced. The frames are delivered to the site, the hardware is on order, and someone notices dust boxes installed directly where card readers or electric strikes needs to go. Or there are no back boxes of any kind, just a hole in a frame. The prep is wrong, the dust boxes are in the way, and the job cannot move forward until the proper back boxes get installed for wiring. It is frustrating, it is expensive, and it happens far more often than it should.
This is the missed box problem. And while it feels like a one-off mistake every time it happens, it is actually a predictable outcome of a process that has never had a proper standard behind it.
How Back Boxes End Up in the Wrong Place or Missing Entirely
Hollow metal door frames have been in use for over 120 years. They were never designed to accommodate wired access control devices, and to this day there is no industry standard for how wires should be installed inside them. That gap creates a coordination problem that plays out the same way on job after job.
The frame fabricator builds what they are given. If the specification does not clearly identify where access control devices will be located, back boxes and dust boxes end up placed by habit or assumption rather than by design. The electrician installs a conduit where it makes sense for their scope. The security integrator arrives weeks or months later and finds unconnected conduit, or missing conduit to a device to be provided by the owner.
Nobody made a careless mistake. The process just never gave anyone the information they needed to get it right. Devices that fall outside the traditional hardware scope are especially vulnerable to this. Door position switches and card readers are often specified in Division 28 or furnished by the owner, which means they frequently never make it into the hardware set at all. The frame fabricator has no way to account for something they were never told about.
Why the Fix Is So Painful
When a back box conflict surfaces on the job site, none of the available options are good. The frame may need to come out of the wall so corrections can be made, which means coordinating removal, repair, and reinstallation while the project schedule absorbs the delay. Shipping back to the fabricator is an expensive, time consuming option, so field welding is sometimes proposed as a faster alternative, but it requires a certified welder on site and creates real risks in finished or occupied spaces. Surface mounting or rerouting around the conflict gets the device installed but produces a result that looks exactly like what it is — a workaround.
Every one of these fixes costs time, money, and in most cases both. And because the problem tends to surface late in the project when schedules are already tight, the cost compounds quickly. For a closer look at how contractors have handled last minute corrections, the Last Minute Corrections blog covers that scenario in detail.
What Proper Coordination Actually Requires
The missed box problem is not a fabrication error. It is a coordination failure, and solving it requires addressing the process before the frame ever goes into fabrication.
Every access control device on a door frame needs to be identified and located in the hardware set before the frame is built. That includes door position switches, frame mounted card readers, and any owner furnished devices that might otherwise be handled entirely outside the hardware scope. If those devices are not documented, the frame fabricator cannot account for them. The result is a frame that was built correctly according to the information it was given, but is wrong for the job it has to do.
Frame Frog is designed to eliminate this conflict at the source. Because Frame Frog installs inside the door frame and serves as its own back box, there is nothing for an electrical box to conflict with. The pathway and the termination point are built into the frame from the start, so the security contractor arrives at a frame that is already ready for their devices.

For a detailed walkthrough of how to document access control devices correctly in the hardware set and coordinate across spec sections, the How to Specify Frame Frog guide covers the full process. General contractors and installers who have dealt with back box conflicts on previous jobs will find it directly relevant.
The Problem Is Predictable. So Is the Solution.
The missed box problem feels like a surprise every time it happens, but it is the predictable result of a process with no standard and no single point of coordination. The trades involved in an access controlled door opening are working from different sets of information, on different schedules, with no shared framework for where devices go and what the frame needs to accommodate them.
Specifying Frame Frog should be your Standard, with each device location documented in the hardware set before fabrication begins, closes that gap. It gives every trade the information they need, eliminates the conditions that produce back box conflicts, and means the job site conversation shifts from how to fix a problem to how smoothly everything came together.
