Anchor Bolt Slab Installation
1. Clear the area where the cross frame is to be as-
sembled to provide safe working space. The area
must be secured with barriers or roped off.
2. Cast into the slab eight - 1-1/2” 8 UNC X 6’ mm
threaded rods attached to the anchor bolt channel
to secure the cross frame.
3. The anchor bolt channel should be 8” off the bot -
tom of the slab, ensuring the threaded rods are 1’
- 8” (506 mm) above the top of the slab (Figure 7).
4. The threaded rods must be spaced 9-7/16” (240
mm) apart (Figure 7).
