Sign accessories are used to create, mount and support signs. They include sign mounting adapters, sign making film and placard holders. Sign mounting adapters lock onto signposts to display different signs around an office or facility. Sign making film is used with graphic design equipment to create custom signs. They come in a large variety of colors. Placard holders display placards that identify the types of hazardous materials that are being stored in a specific area or transported on a vehicle. Placards can be easily changed in and out of holders to reflect current safety hazards.
