I was worried a bolt on, after market, product would not install to my standards. I honestly don't care for the bolt on look. This product installed easily and very securely. I am strong weight 300 lbs. and can hang from it. Try to pull off, doesn't budge. I am very happy with the strength and stability.I put 3 bars on the roof of my chevy van. I am confident, anything That I could reasonably attempt to attach would be secure.
