They’re made of rugged clear acrylic with both sides open. Just insert your sheet or sign in either side. To update the literature push the new piece in either side and it will push the old one out the opposite side. Mounting tape is already on the back of the display. Just peel and stick, it’s that easy.
Do you require something a little different? Custom sizes, either smaller or larger are available (sometimes with minimum quantities). Call us at 1-800-376-2194 to discuss your needs.
