*The Weigh Frame assembly is ideal for vessels with bottom piping and applications too heavy for weigh rails, making tank and vessel installations easy. 1K-10K Weigh Frames are constructed of 7” channel @ 9.8# per foot and the 20K frames are constructed of 8” channel @ 20# per foot. W1 & W2 are the actual scale width and length ordered. Add ½” to the length and width dimension for W if ordering lips. 1K-10K frames are 3.5” tall (H) and 20K frames are 4.5” tall (H). Add 1” to height (H1) if ordering lips.
