A Proudly Canadian Product! Our gallery style stretcher bars are made of kiln-dried and knot-free Basswood. This type of wood is light yet strong, making it ideal for the thicker dimensions of our gallery stretcher bars. Each bar features a 1.5" profile and is precision cut to join together in a secure fashion. Every stretcher bar 24" and longer also has a centre slot milled to accept a crossbrace for support (bars 50" or longer contain 2 slots). Gallery Stretchers & Crossbraces are available in even lengths from 12" to 72" and are sold in singles (prices shown are not for pairs).
