First Aid Projecting Signs can be installed on a door, a wall, on top of equipment, in a hallway, or anywhere else in a way that they project from the surface at a right angle. Projecting L shaped signs are bent at a right angle, so you can install the flange side directly on the wall (no need for a separate bracket). On the flange are two drill holes for mounting. Use screws or double-sided adhesive tape to mount the sign. Signs are double-sided to be spotted from both directions. We also offer Projecting First Aid V-Signs which have two flanges and two pre-drilled mounting holes on each flange. Just use some screws to fix the sign on a flat surface using the drilled holes. If not screws, you can use adhesive tape. All necessary hardware is included in the order. Even our 180 Degree Projecting Signs can be installed in the same manner.
