The fixtures we offer to mount VeX™ Pods come in several different sizes to fit various pipe diameters. Sometimes it can be difficult to determine the appropriate fixture, so we developed a Pipe-Fixture ruler to simply the process.
You can download the ruler here. Once you have the PDF file, you must print it out without scaling the image at all (it is a ruler, after all). Cut the ruler out and cut out the center section as noted on the printout. Then you can wrap the ruler around the pipe on your boat and the ruler will guide you to the proper fixture for your installation.
