Hollow Frame Spacer (also known as EconoSpace)

Hollow Frame Spacers are a pH neutral plastic adhesive backed art-glass separator that adheres to the edge of the glass in a picture frame. They are used to create airspace between the artwork and the glass in a frame (wood or metal). Airspace facilitates breathing room for the artwork which helps prevent mold growth and paper buckling. Also known as EconoSpace, these spacers are available in varying depths in 5' lengths in clear, black, and white.
