Spring bolt
Encyclopedia
Roger Rock of Rock Lock Fastening Systems, Inc. invented the Spring Bolt in Spring of 2008. See this website for a video demonstration of the product and it's uses: http://www.bestrailinghardware.com/

The Spring Bolt is specifically designed to fasten handrails together and newel posts to a deck when building staircases. This fastener cuts the time and required skill level of the assembler in half. It consists of two springs with a screw attached at one end of each spring and a metal bolt that is used as a guide. Once the springs are screwed into the end of a section of handrail you drop the bolt into one end of handrail section and twist the sections together. This creates tension or a clamping effect. The Spring Bolt has passed engineering load bearing tests with flying colors and therefore is deemed safe and truly effective.

Mr. Rock is a high-end stair builder in West Palm Beach, FL. He has owned and operated Rock Wood Works (http://www.rockwoodworks.com/) for more than 25 years at this writing. He has always thought the traditional way of attaching stair railings, with a rail bolt, took a mid to high-level of expertise, it was time consuming and the end product was not satisfactory to his or his client's level of perfection.

After leaving a beautiful home with a set of stairs that Rock Wood Works installed, Mr. Rock was not satisfied with the traditional method of attaching the railings. When standing on the ground level and looking up at the stairs he could see the old fashioned rail bolt and thought "There has to be a better way!". The concept came to him while driving back to his shop in Lake Worth, FL.

After that day, Mr. Rock has pursued a patent, started a website, attended dozens of trade shows, and worked very closely with large and small home improvement chains to get his products on their shelves. The testimonials speak for themselves. It's a genius idea that will certainly be used for years to come.
