The buildings and the hardware
Most buildings in Montgomery County present a mix of older wood doors and newer metal units, and that mix determines the hardware you see. Older houses often have deep-set doors with mortise locks or rim cylinders; the boltwork is heavier but parts can be worn, striking misaligned plates or splintered frames. Apartment complexes and recent construction use bored cylindrical locks or keypad deadbolts, mounted in thinner doors with different backsets. For storefronts you’ll see exit devices and commercial-grade cylinders. Each situation calls for the right parts: longer screws and reinforced strikes for older frames, or grade-appropriate cylinders and anti-drill plates for commercial doors.
