NOTE: Center column weld (VTDL-0541) will be installed from the inside of the tank. Place shim plate (VTDL-0403) in position on the threshold weldments. Place bottom of the column near the threshold weldment and tilt the column upward into position. Bolt the column to the header as shown. Install shim plate prior to tightening bolts. Bolts may be hand tightened at this time. Do not fully tighten until door is completely installed. Be sure that all the door panel plates are aligned. Do not weld the center column to any part of the door frame. Center column weldment must be removed when door is opened.
