Dump Hopper Installation
Pre-assemble the dump hoppers and flashing angles to the floor sheets. Place a dump hopper under the
floor sheet and align it with the pre-punched large hole. Place a flashing angle on top of the sheet across
the outer edge of the hopper entrance with the interior of the angle facing the sidewall. Screw down
through the angle, sheet and hopper with 5/16" x 3/4" self-tapping screws.
(See Figure 8F.)

Floor Sheet Installation
The assembled sheets can now be laced over the framework. As the sheets are placed and overlapped
they are to be screwed down to the rafters using 5/16" x 3/4" self-tapping screws. There are certain holes
in the sheets that should not be screwed down at this time to mount leveling band posts later. See chart
below . All holes are counted from the sidewall sheet up to the center of the bin. (See Figure 8G.)
