Gray Flex’s “Flex Metering Device” is a tool that allows you to use the specific amount of flex duct needed (ie. 10′ from of a 25′ piece of flex) and still be able to leave the left over (15′) in the BAG for another time. Just as you can tape a box back up with your left over flex, you can now do the same with a bagged flex. This helps you avoid wasting flex (and money). Check out the video to see exactly how it works!
