School Door Was Falling Apart From a Broken Hinge Reinforcement: ABH A571HD Continuous Hinge, Aventura
The facility manager at a school in Aventura emailed me about a door that was falling apart. The bottom hinge had broken from the frame, and the hinge reinforcement was broken too. Instead of replacing the door frame, I installed an ABH A571HD continuous hinge, through-bolted to the door, in an hour and a half.
What the email said
The facility manager wrote, “The door is falling apart and it’s a safety hazard, so we need to fix the door as soon as possible please.”
What I found
When I got there, I found the bottom hinge had broken from the frame itself. Right away I saw that the bottom hinge reinforcement was broken too, so the door had almost fallen apart. This is a door students go through hundreds of times a day.
Why a continuous hinge instead of a new frame
In other cases, I replace the regular hinges and I’m done. Here, the hinge reinforcement was broken as well. That left two choices: replace the door frame and the hinges, or put in a continuous hinge. I went with the continuous hinge.
The work
I installed an ABH A571HD heavy-duty full-surface geared continuous hinge, 83 inches. Some people call it a piano hinge. I through-bolted it, as the manufacturer’s instructions call for, and the through-bolts reinforce the hinge to the door.
The job took an hour and a half: assessing the issue, taking the door down, removing the old hinges, installing the continuous hinge, and tightening the lock hardware, the panic device, and the door closer to make sure everything worked perfectly.
What was on the invoice
The invoice was for the continuous hinge and the installation, nothing else. I didn’t charge for tightening the lock and the hardware. It’s a high-traffic door, so it has to be well maintained. My pricing is upfront, and you approve it before I start.
What a real locksmith knows
When a hinge breaks from the frame, I check the reinforcement right away. If the reinforcement is broken too, through-bolts are what reinforce a continuous hinge to the door, and that is how I save the customer money instead of replacing the door frame.
