There are several ways to mount the signs on doors, depending on your preference - Mounting Holes and Screws: There are three hole-placements to choose from - two top holes, two side holes, four corner holes. Screws are included with most of these hole options. Mounting screws and holes are the most secure method of installation. Foam Adhesive Strips: These are included with most of our door signs. Double-sided foam strips work well on clean and dry surfaces and secure the sign permanently. If the surface is dirty or porous, the bond will not work well.  Hook and Loop fastener strips (Velcro): Adhesive-backed Velcro strips are a clean option for those looking to change the position of their signs after installation. If rooms change regularly, you can easily take the sign off the surface and relocate it to a new location without creating any mess. Magnetic strips: Magnetic strips are a great option in case the signs need to be relocated or replaced. However, the bond is not as strong, and therefore, magnetic strips are recommended for static surfaces only and not for moving surfaces like doors. Wall Standout Bracket: The sturdy metal bracket allows you to attach the sign perpendicularly to the wall. Suction Cups: Hang your sign on a glass or metal surface with suction cups. The hooks are threaded through the holes. Tube Adhesive: High-Bond adhesive bonds well to a flat surface like concrete, walls, plastics, metal, or wood. The adhesive takes 8 hours for a full cure but will achieve excellent adhesion after only 10 minutes.
