vertical frame cable railing. designing a railing using vertically run cables as in-fill. Top and bottom rails are necessary in a vertical railing using cable,because mounting and tensioning hardware is attached to top and bottom rails instead of end posts. We recommend schedule 80 pipe or 2"x2"x1/4" square tubing for both the top and bottom rail, because of the forces applied when the cables are properly tensioned.
Schedule 40 vs. Schedule 80 Pipe Not all pipe is made the same. We ONLY use Schedule 80 pipe. Any structure I've seen with lengths greater than 4 feet who tried to cut costs by using Schedule 40 pipe has proven to be a structural nightmare. Tons of bending."
The Badger Meter wireless 228PV flow sensors are designed to measure water flow in PVC pipes. These sensors consist of a removable, nonmagnetic sensor in a schedule 80 PVC tee with solvent-weld socket end connections. They are available in 1-1/2" to 4" sizes.
