The Morelli Bondable Double Buccal Tubes .022 Roth Convertible combine a main archwire tube with an auxiliary tube for additional mechanics, with values supplied for both the upper and lower first and second molars. Produced in MIM stainless steel with a low profile, rounded surfaces, a lowered hook and an anatomical base, and the cap can be removed to convert it into a bracket.
