The Gauge Case is a laptop style nylon bag custom designed to hold Retrotec gauges. This case has a Velcro pad in one of the compartments on which to secure the gauge in a plastic sleeved holder. The same holder can attach the gauge to the door panel Velcro while doing a test. The many compartments and pockets on the case provide ample space to keep your fan umbilicals (pressure tubing), AC adapter/spare batteries, tubing accessories, and all items that come with the gauge.
