Two-Ring Door Installation
Before beginning the installation, be sure the correct door has been received.
Figure 1A
1. Remove inner door panels and outer door cover. Apply two rows of rope caulk around all four (4)
door flanges: On vertical flanges, one row of caulk should be applied between the two vertical rows
of bolts and the other row of caulk should be applied between the door frame and the first row of
vertical bolts. On the horizontal flanges, a row of caulk should be applied on each side of the row
of bolts.
NOTE: For the 2.66" corrugation, all caulk is applied to the outside of the door flanges and the door
flanges are applied to the inside of the sidewall.
NOTE: For 4.00" corrugation: the top of the door frame goes to the inside of the sidewall and the
bottom of the door frame goes to the outside of the sidewall. Therefore, depending upon
location and overlap, caulk will be applied on either the inside or the outside of the door
flanges.
See Figure 1A for illustration.
With inner door panels and outer door cover removed, set door frame into opening. Insert several
bolts at four (4) corners of door frame and sidewall, do not tighten until completing
Step #2 .
2. Reinstall inner door panels at original locations. Close latch bars to lock panels in place. Be sure
that panels are fully seated over all bearing pins. Install inner panel hinge assemblies per
instructions in manual PNEG-301 with hinges. NOTE: Do not distort door frame with use of
alignment or drift punches - if necessary, drill or ream holes to insert bolts in door frame. Now
tighten frame bolts starting at center and working toward top and bottom on each side. (On
2.66" corrugation bins, be sure bottom ring of sidewall is installed before tightening these bolts.)
3. To make panels easier to operate, loads on pins should be uniform. To do this, loosen all bearing
pin bolts with inner panels latched. Then, retighten all bearing pin bolts.
