PNEG-529 Cor-Lok and Cut-Lok Flooring for Non-GSI Bin Diameter
* Installation, Spacing and Quantities of Air Flow Supports Under Channel Lock Floors
NOTES:
1. Use a maximum spacing of 16" for perforated corrugated flooring.
2. The number of supports listed is based on the maximum peaked capacity of each bin.
3. Use extra single supports for split floors.
4. Extra supports are required for grain recirculating equipment. Use the manufacturer’s
recommendation for the number and spacing of extra supports. NOTE: For grain flows, air flow
supports are doubled in a 14' diameter in the center of the floor.
5. Contact a representative for air flow supports required for larger bins and deeper grain depths.
6. * Increase the number of supports by 5% when used with 6-3/4" wide MFS
floor planks.
