ULTRA THIN GALLERY FRAMES PROFILE 102UT The 102UT custom frame is designed to accommodate a 1/2" spacer and 1/2" strainer. It is available in 5 woods and 30 finishes. It is used both for artwork that is matted and "floating" on a museum board. Because of the extreme thinness spline joining is required. Strainers are highly recommemded to add stability and strength to the artwork package as well as provide a means of attaching the hanging devices. Optional components include: wood spacer, strainer, museum mat and backing board, acrylic, and archival backing board.
