Been using Remora, but the 2x 2.5 glands dont come in 20 mm hole size and the 10,s and 6,s are areal pain in the backside as they dont fit any bloody standard holes, any one know a make that are designed to fit standard metal CU,s with standard holes sizes, so glad I did not buy the installer kit, even the ones that do fit namely the 1.5,s are so close together that tightening one un does the one next to it
