This is a light duty kennel that I strapped some 2 x 2's across the top with plumbing strapping and then attached sheets of tin. Works great and it didn't weaken the panels. This is a 6 x 10 kennel. I would use 2 x 4's for a 10 x 10 light duty kennel. For heavy duty 10 x 10
kennels I would and have used 4 x 4's.
