Tubes may be ordered with Both Ends Open by adding “ OBE ” to the part number before the length. Normally stock lengths of multiples of 6 inches starting at 12 inches are cut off making the tube approximately 1/2 inch shorter, which in most applications is not a problem. For example a P11F-12 would be cut to P11F-OBE-11 1/2 . However, an actual 12 inch OBE can be made by cutting down the next standard length (18 inches) but it would add additional material cost (5 1/2 inches) for the 1/2 inch lost. Tubes with, or without, mountings on one end can be open both ends. Example: P16F-OBE-18 .
