"We’ve been enjoying a few different Maker Pipe Builds. The best is the flip doors we’ve now made for two of our hunting blinds using Maker fittings and ½” EMT. They are lightweight and simple to push out of the way when it is time to shoot. I made some stops to hold them at the right tilt using threaded inserts in the pressure treated rail with bolts at the bases. These are miles above anything we used in the past to cover the shooting hole. Everyone loves the ease of use and that you can still see the birds coming in while remaining hidden. I also built a front rack for our Argo. Sturdy as can be using ¾” EMT" - Dale
