We used these brackets to install a 5/12 pitch roof over two 40-foot high cube containers spaced 20 feet apart, to create a tractor shed. The brackets made placement and attachment of the trusses a breeze. Very high quality, sturdy brackets that fit the trusses like a glove. We also found the included screws and drill bit to be of high quality. My contractor wanted to know exact dimensions the day before installation and CMW emailed those to us within an hour or so after a call to them. Very impressed with the product and company and would definitely purchase again. We installed just one screw to the container initially in case small adjustments were needed, then installed the other two after through-bolting the truss to the bracket, and that approach worked well for us (but may not have been necessary).
