We've been using 3AN Tee's for 20+ years and the standard offerings have a major flaw. The middle is too small and getting an AN wrench in there so getting all three 3AN's tightened at each side is a pain. We finally designed our own and fixed this by bulking up the middle giving it way more grab! Cut from 6061 Aluminum with Mil-Spec tolerances and anodized Chase Bays signature semi-gloss black.
