The Morelli Bondable Buccal Tubes .018 Edgewise Double Convertible carry the main archwire plus a second auxiliary lumen on the first molar. Built to the Edgewise standard, they carry no built-in torque or offset, and the cap can be removed to convert the tube into a bracket.
Key Features
Double tube — a separate lumen for auxiliaries alongside the main archwire
Convertible cap turns the tube into a bracket when needed
Edgewise standard — zero torque and zero offset in the tube
Lowered hook and rounded shape for elastics and auxiliary attachment
Large compound contour base adapts to the molar surface
Low profile and smooth rounded surfaces for patient comfort

Clinical Applications

Why Convertible?
Removing the cap turns the molar attachment into a bracket without rebonding — useful when the finishing stage calls for direct wire access. The second lumen stays available for an auxiliary either way.
