- Electrical conduit stub outs should be no less than 3” above grade with a minimum of 18” length of supply conductors from the end of the conduit stub outs.
- Maximum conduit stub outs size: (2) ¾” conduit sweeps.
- Orient the J-bolt anchor assembly so the template bracket is flush with the final grade. The top of the J-bolts should be between 5 /8” and 7 /8” from the top of the template bracket. (the height of the J-bolts are pre-set at the factory).
- The concrete pour form should be a minimum of 9” across in any direction and at least 18” deep.
- Fill the concrete form (by others) with concrete (by others). For best results, make sure the concrete is flush with the top of the template bracket, is level, and smooth.
