While constructing a ceiling suspended shelves in garage I was facing problems with attaching crossbar to ceiling joist I just couldn't get lag through 2x4 into middle of joist it was always off and I wasn't sure of how well is the connection.
So I looked into this strong tie which kind of seemed like good solution to my problem and also since it connects 2x4 on edge it will give more surface area to connect vertical members. My question are
- Will it provide strong connection with crossbar and joist for shelves to hold say 300-400 pounds?
- Does it matters where the vertical members are attached on crossbar or do they must be on where crossbar is fastened to the joist?
- Should I use nails or screws to mount the brackets?
