IMPORTANT: This GSI commercial 2 ring door is designed for use in the 2.66" corrugation 90' diameter
NCL tank. This door should not be installed in any tank not manufactured by GSI.
Door Placement
The commercial 2 ring door is installed in the bottom 2 rings. The door should normally be placed in line 
with the conveyor. The center of the door must be positioned directly below the vertical seam of the ring 
above it. The door can not be assembled properly, if the vertical seam is offset to one side of the door. 
An intermediate discharge well should be located near the wall to clear grain from the area of the access 
door. The two (2) anchor bolts for the door should be drill in anchor bolts placed after assembly of 
the door. See “sidewall and stiffener door attachment” section 
for more details on the
anchor bolts.
The door has an inside frame weldment and an external frame weldment/assembly. If the tank has not 
been erected, the internal frame weldment should be placed inside the tank before erection. If the tank 
has been erected or erection has begun, it will be necessary to remove sidewall and stiffeners in the door 
placement area to place the inside frame weldment. A long and short special door sidewall sheets are sent 
with the 2 ring door. 
for door placement and special sidewall sheet usage.
