The Morelli Bondable Buccal Tubes .022 Edgewise Double Non-Convertible carry the main archwire plus a second auxiliary lumen at the posterior anchorage. Built to the Edgewise standard, they carry no built-in torque or offset, and the cap is fixed — the tube does not convert into a bracket.
Key Features
Double tube — a separate lumen for auxiliaries alongside the main archwire
Edgewise standard — zero torque and zero offset in the tube
Non-convertible cap stays closed for the whole treatment
Lowered hook for elastics and auxiliary attachment
Large compound contour base with side positioning indents for accurate placement
Low profile and rounded surfaces for patient comfort

Double or Simple?
The second lumen is the whole difference — it takes an auxiliary without disturbing the main archwire, where the simple tube has a single lumen. This version is non-convertible: the cap does not open, so the attachment stays a tube from bonding to debonding.
