Inside and Outside Ladder Installation
Center the ladder below the roof ladder. Use bolts, to mount ladders, in the horizontal seam, 18 ¾” apart at the inside ladder locations.
Place the ladder over the bolt and add a second nut. Place another bolt on the next lower horizontal seam. Tighten the ring, place the first ladder section over the existing bolts, add a second ladder on top of these bolts, add nut and tighten. Ladders are meant to overlap one another on the same bolt. Flat washers may be needed.
Repeat this process until bin is complete. Inside ladders usually end two rings above the concrete. Mounting hardware is not included.
