The Locksmith's Lever and Panic Bar Retrofit Book

By David Calvin

This book teaches you the art of installing panic bars, retrofitting newer products on previously prepped doors, and installing levers on doors that aren't prepped for levers. If you are not doing this kind of work as a locksmith or a handyman, you are missing out the most profitable jobs. In this book, you will see the Von Duprin type rim devices, the Sargent 8800 series, the Yale, and the US LOCK 2876 being installed. We talk about Don-Jo cover and remodeler plates, drilling, cutting, measuring, and just about everything else. This book has 45 pictures. Your price for a nice grade one panic bar and outside trim is sometimes over $1,000. Add $500 to $900 to that price, and you get the picture. Install time for a retrofit runs about two hours. Get the book, read it through about three times, and you'll be ready. This book is $9.99 at Amazon Books.
