For the locksmith, door work is divided between installations, repairs and upgrades. Most often, locksmiths are called out to repair damage caused by forced entries or abuse of the door, or to upgrade items for electronic access, or fortify the door against attacks.
It’s best to arrive at a repair job with an assortment of solutions loaded in your vehicle. Also you must realize that the door may not properly lock after being attacked, and the customer doesn’t want to leave the premises unprotected overnight knowing it has been compromised. You can get a pretty good idea what you can expect to need when you find out some details prior to heading over the premises.
Sometimes the service call will be to address doors damaged from old age where the door or frame will no longer support the original hinges or pivots. The door and frame may be too damaged to re-use.
If it is a fire door, maintaining code compliance is an important consideration.
I’ve seen many metal doors which appear to be intact, but have actually rusted from the inside out, and were literally held together by the several layer of paint which had been applied over time, ostensibly for the purpose of maintenance, but probably to conceal the problems and avoid the cost of replacement and repair.
I have also seen doors which were salvageable by using offset pivots, continuous hinges, and wrap-a-rounds to reinforce and rebuild damage.
These measures provide a quick remedy to the immediate issues, and the owner may roll with them even if you explain that the Fire Marshal might still question the integrity of the opening during annual inspection and require more extensive repairs. It all has to do with the AHJ, the nature of the occupancy and the primary function of the particular opening.
When going to a site for the purpose of installing access control, sometimes the subject door is not healthy enough for a mere upgrade. Out of necessity, you’ll need to identify damaged doors and know the appropriate products to perform the repair.
If you are called to do a rekey or adjust a door or door closer, sell your customer on the benefits of increased security that the installation of items such as latch and cylinder guards can provide, making them a good very good investment.

We asked Ray Zehrung, President and founder or Marray, Inc. for some comments on hinges.
How important are hinges to a door’s proper operation?
Many people don’t pay much attention to hinges on doors. They pull the door open, the hinges usually work as designed and they never give them a thought. When most problems in door openings occur, it’s usually the lock or other latching device (or handles etc. ) since those articles are the ones we directly interact with. When a handle or pull, or push bar is not operating correctly, we notice immediately. We have a tactile relationship with the hardware we use for entry or egress.
Hinges, although rarely noticed, are in fact, one of the most important design elements in a door opening. If your door is too heavy for the hinges, the hinges will begin to sag, the latch may not engage fully into the strike plate and the door may begin rubbing on the threshold.
How do you select the correct hinge for a door?
Many Standards are used by architects and contractors when specifying hinges for openings. Such Standards may include those of the NFPA (National Fire Prevention Association), BHMA (Builder’s Hardware Manufacturers Association) and others.
What are some considerations for special applications?
Just as specifying or installing an incorrect standard hinge can bring about future problems, so can the incorrect installation of a Power Transfer Hinge (PTH).
PTH connectors are used to bring power from an access control system to an electrified lock, panic device or other remotely activated piece of door hardware. Not all PTH connectors perform in exactly the same manner. Some are made for low power solenoids or motors and therefore only have small conductors. Usually between 26 and 30 gauge. Some are specifically made for larger solenoids that require a larger amperage draw.
At Marray, a leader in PTH technology for almost 25 years, we make and distribute a multitude of PTH connectors for every need. Our patented technology allows for us to offer a PTH for almost any situation. From our best selling 2+4 model (2 each 20 awg and 4 each 28 awg for large draw solenoids), to our 2+10 model, we strive to provide the exact PTH needed for any job. Using a PTH is a desirable method of providing power due to several factors: The wires are hidden and therefore, are less likely to be known as connectors and less likely to be tampered with. The Marray PTH is listed for 3 hour openings and thereby maintains the fire listing of the rated assembly. They are extremely durable, as they are required to be tested for openings of over 100,000 cycles, while being powered on and off for 5 seconds.
It’s always important to make sure the hinge you specify or purchase is durable for your application and is rated for the hardware you need to operate. An underrated hinge can short, burn out, or not last as intended.
There are many providers of PTH connectors. Just be sure you find one that works for your application, so you can leave the job, secure in the knowledge that you won’t have to return for any repairs or replacement.

They can install one of these in about 5-6 minutes if they already have the cylinder off the door (7-8 minutes if not).

Hager Geared Continuous Hinges
Hager’s Product Marketing Specialist Ginny Powell says continuous hinges rank way up there with the wheel and sliced bread as one of mankind’s greatest inventions. Here are excerpts from one of her recently published articles she has offered to me to include in this article.
There are two types of continuous hinges -the pin-and-barrel and the geared. The pin-and-barrel continuous hinge (sometimes known as the piano hinge) has two leaves joined together by a pin. The geared continuous hinge features gear teeth that mesh together under a cap that runs the length of the door.
The geared continuous hinge was patented in 1963 by Austin Baer, and in 1968 he earned a second patent for adding thrust bearing to his original design, known as the Roton® Continuous Geared Hinge. The patent expired in 1985, and Hager Companies purchased Baer's company in 1989.
Today every major U.S. commercial hardware manufacturer offers a line of continuous hinges.
These characteristics mean that continuous hinges are often installed for openings that are subject to high traffic and abuse, such as gymnasiums, health care facilities and sports complexes.
"As the population continues to grow, the demand on door openings increases with security and safety at the forefront," explains Dan White, Manager of Product Development for Hager Companies. "For these high-demand openings, the continuous geared hinge remains the smartest choice for the life of an opening."
Here are a few examples of where you can install a continuous hinges:
HOSPITALS, STADIUMS, ARENAS AND SCHOOL GYMNASIUMS: Over time, the doors that get a lot of use also tend to "come off their hinges" and sag or warp. Because a continuous hinge runs the length of the door, it keeps the door in constant alignment and eliminates this issue.
PRISONS AND BACK DOORS TO CONVENIENCE STORES AND STRIP MALLS: A geared continuous hinge can keep a building even more secure than a standard hinge because there isn't a pin that can be removed. In fact, prying off a continuous hinge would be time-consuming - which acts as a deterrent.
STOREFRONTS: Doors allow air to escape, which can be a great source of energy loss when trying to warm or cool the air (depending on the time of year). A continuous hinge helps close the gap between the door and the frame - creating a tighter seal.
Continuous hinges are generally available in five standard lengths: 79, 83, 85, 95, and 119 inches, and can be cut to the exact length needed during the installation process (varies by manufacturer). With the frequent use of electronic locks today, continuous hinges can also be modified for concealed electric through-wires, exposed electric switches, and electric power transfers.
Though continuous hinges are not as commonly used as their standard counterpart, they are a financially smart hardware solution. They are durable, long-lasting and solid, which allows for an extended life for the total door opening.
Following are some of Hager’s continuous hinge products:

Frontline Defense
The construction of the door and frame is an important factor when determining an opening’s vulnerability to attack. Most doors are very vulnerable to forced entry, even when they are equipped with auxiliary locks like deadbolts.
Historically felons have found easy access to property by merely using a pry bar or similar device to pop open doors to gain access. To create the greatest possible deterrent against this type of entry, Frontline created the full door latch protector.
Designed for both out-swing and in-swing doors, the system is offered in both aluminum and steel material and available in several standard colors, and can be custom ordered to fit any size and color required.
Installation hardware is included with all orders and custom latch protectors are also available.
