Magnuson Glassnox Displays - Wall Mounted
Magnuson Glassnox is an extensive line of display holders for information and graphics. The basis of Glassnox is a brushed stainless steel frame with an aluminum back panel and crystal blue acrylic or tempered glass front cover. All you do to change out the information sheet is push up on the front cover, insert the new information sheet, then push the cover back down into the frame. Done! The secret is the spring-loaded back. It keeps the sheet pressed tightly against the transparent cover and the cover pressed tightly against the frame.
Glassnox is available in a wide variety of sizes, beginning at 4-7/16" H x 3-1/16" W. The largest is 33-3/8" H x 23-1/2" W, so it's rather likely you can find the size you need.
