Drilling into concrete to hang a 70lb heavy bag?

I am planning on attaching this to the ceiling in order for me to be able to hang a 70lb heavy bag:

http://www.amazon.com/Everlast-4680-Heavy-Bag-Hanger/dp/B00076ZE0I

But i am dealing with concrete and there is no mention of that in the manual, it comes with two 5/16” x 2″ lag bolts that i am supposed to drill into the ceiling and if so then what size of masonry drill bit should i use and also what size of Rawl Plug?

Thanks!

To use the lag bolts you will need to buy a product called a lag shield. For a 5/16 lag shield you need to drill a 1/2″ hole. Lag shields come in 2 sizes, “short” and “long”. Long will hold more than short but you need a minimum of 1-3/4″ of bolt going into the shield. This means you may need to also buy longer lag bolts, depending on the thickness of the bracket and washers.

My advice would be to ditch the lag bolts all together, and buy a couple stud anchors instead. Stud anchors ( also known as wedge anchors, redheads, or qwik bolts) don’t come in 5/16, but even a 1/4″ wedge anchor will hold about 3x more than a 5/16 lag sheild, plus you are drilling a smaller hole ( a 3/8 wedge anchor takes a 3/8″ hole)

Drilling into poured concrete ceilings is especially tough, because much of the stone used in the concrete mix settles at the bottom of the pour, so if you have access to a hammer drill, use that with a good bit. I wouldn’t rent one for 2 holes, but it will make the job much easier if you can borrow one. Good luck
