Tor VM Lug matrix bands combine the industry leading quality of Tor VM metal with a popular lug matrix pattern. The lug matrices allow greater wrap of the buccal and lingual surfaces than the standard Tor VM sectional matrices. They also have a useful hole at 3 points of the band which make placement and removal easier (especially when used with the Tor VM Linear Pliers).
