Sliding Signs consist of a 60 mil thick engraved plastic plate recessed within a solid anodized aluminum frame. The frame is available in a few colors and finishes. The plastic plate has two panels. The top sliding panel has engraved text, while the static base plate is screen-printed and/or coated in vivid color. Installation is simple too - use the foam adhesive strip to mount the sign on a door. Or, you can opt for magnetic or Velcro strips. Signs are easy to maintain, incredibly durable, and last for years and years.
