Harmony Posterior Dual Arch Tray
The narrow stainless steel bar at the back is only 2.6 mm in diameter, preventing tuberosity impingement, while still giving it rigidity equal or better than any other disposable Posterior dual arch tray.
The Harmony Posterior Dual Arch Tray narrows to the back of the mouth, and the side walls are low. Other trays stay the same width, and even become larger in places towards the back of the mouth. This is the cause of tuberosity impingement and poor bite registration.
The steel bar in the Harmony Posterior Dual Arch Tray offers superior rigidity, which is a large factor avoiding distortion of the impression.

In an extensive study done in 2014 by an Utah-based independent dental products evaluation organization*, the Harmony Dual Arch Trays were highly rated.
