I've never bolted anything into concrete and want to bolt my power rack down. What do I need to know? Its 2" squat tubing and doesn't have any holes in it so I need some type of bracket, or to drill through the tubing. How deep? How many bolts etc? Is there any kind of bracket that can be opened in the future to move the power rack?
Please be as specific as possible. Previoulsy I wedged my rack under the I-beam of the house with 2x4 underneath the rack and 1 inch wood to form a tight fit. I was able to have at least 360 pounds of band tension on it with no movement at all but my new basement ceiling is about a foot higher.
