Corner Section Tubing - For use in 90˚ corners using tubed corner sections
See Tubed Corner Sections Drawings Page
Note that the inside of the tubing cannot be sealed to prevent moisture inside the tubes. Therefore, we recommend stainless steel tubing for all exterior tubed corner section applications, to prevent rust inside the tubing.
