The Complete Handbook of Door Knobs & Handles

Finally, a handbook that treats door hardware as the technical product it actually is instead of just an aesthetic choice. I've been a facilities manager for fifteen years and I keep coming back to Chapter 1—the explanation of why material grades matter and how to read the difference between residential and commercial specs saved me from a really expensive specification mistake on our last renovation. This is the book I wish I'd had when I started.

Exactly what I needed as a new installer. The installation chapter is incredibly detailed and the troubleshooting section has already saved me three callbacks. My only wish is that there were more photos of common installation errors, but the text descriptions are clear enough to follow. Highly recommend for anyone doing this work seriously.

I've read dozens of hardware guides and this is the first one that actually explains the engineering behind door knobs instead of just listing brands. The material and finish durability section alone is worth the price—I now understand why certain hardware fails in humid environments and which finishes to specify. If you work in building, you need this book.

Really solid reference. The chapter on choosing hardware based on application is practical and thorough. My only minor gripe is that the business opportunities chapter feels a bit less detailed than the technical chapters, but for someone like me who installs and maintains hardware, everything else here is exactly on target.

As a project manager, I find myself consulting this handbook regularly—especially the specifications and troubleshooting sections. The ADA compliance guidance and the explanation of backset and handing finally gave me language to specify hardware correctly instead of relying on my contractor. Great reference, though I'd have appreciated more depth on smart lock integration.

This is exactly the kind of straightforward technical handbook I've been looking for. No marketing fluff, just concrete information about how door hardware actually works, how to install it correctly, and how to keep it functioning. The maintenance section alone will pay for this book in prevented callbacks. Highly recommend to anyone in the building trades.

Thorough and well-organized, though I found myself wishing the glossary was longer—some of the more specialized finish and material terms could have used more context. That said, the core chapters deliver solid practical information, especially for residential work. Good investment for a toolkit.
