Introducing: CAF Material Gap Gauges!


Selecting the correct gap size for upholstery material clearance used to be a gamble.

Now you can determine the perfect gap needed quickly and easily!

One of the most overlooked steps in the fabrication process of custom panels is accounting for the gaps between the panels to allow clearance for upholstery materials. If you don't plan for the correct gap size your panels will either have a loose and sloppy fit, or be far too tight which can lead to panels that cannot be disassembled for serviceability or lead to the upholstery materials bunching up and looking bad. 


To solve this issue Mark from CarAudioFabrication designed the CAF material gap gauges. These gauges allow you to quickly and easily determine the EXACT size of gap that is needed for a combination of upholstery materials during the fabrication process of your custom panels. Together with Mark we have helped to produce an organizational tray that stores the gauges in an easy to retrieve position, and includes the rabbet router bit needed to quickly produce the correct gap size on your panels. We manufacture these parts here at our headquarters in Phoenix, AZ USA.
