The tees are connected via cam-lock devices or splice bars and may be hung on a 4′×4′ or 8′×8′ configuration. The tees also include hammerhead-nut slots used to suspend the tees from the building structure above and hang AMHS hangers from the tees. Grid stiffeners are included to increase the carrying capacity of the tees.
