When starting to attach hopper sheets to sidewall it is recommended that the first hopper sheet seam
be positioned halfway between leg positions. Lap the hopper sheets as shown
. Apply
two (2) strips of caulking on all seams at sidewall to hopper and hopper sheet to hopper sheet. Use
5/16" x 1-1/4" bin bolts (head to outside of tank) for attaching hopper sheets to bottom sidewall sheet.
Use truss head bolts to attach hopper sheet to hopper sheet. Be sure to place the head of the truss head
bolt on the inside of the hopper. Leave one hopper sheet out to allow room to install the hopper collar.
Be sure to use two (2) strips of caulking between hopper collar and hopper sheets, then put last hopper
sheet in place. After the collar is in place, attach the hopper braces and tighten all bolts.
