Anchor Bolt Placement

Having poured and leveled the concrete, use the center stake and straight 2 x 4 again to find the bolt circle
radius for the outside hold-down brackets. Select a starting point and stretch a pre-measured chord along
the imaginary circle formed by the bolt circle radius. Take into consideration the placement of these bolts
so as not to interfere with the positions of bin doors and transitions. (

Refer to below chart

for necessary

radius and chord lengths.) Take the time and work carefully since accuracy is important.

NOTE: Top edge of slab where the bin wall sets must be held to within 1/8" of level.
