Ceiling signs are used as signposts inside the exhibition halls. Depending on content and application, they are used in different sizes and are installed or hung at least 3 metres above floor level. Whenever required, signs can be quickly taken down and reinstalled without the need for tools. Depending on the exhibition, ceiling signs can also be complemented by individual panels for event-specific information purposes. The primary purpose of both the flat wall and perpendicular signs as well as the ceiling cubes is to signal public facilities such as WCs, cloakrooms, baby-changing and first-aid rooms. All graphic holders can be quickly changed, inserted and secured without any need for any tools. The wall models with bedframe clamps are easy to remove and refit. The signpost provides orientation in four directions with a maximum of four destinations per direction. Special foundation base units are recessed flush with the ground for easy assembly and disassembly, depending on outdoor direction requirements. The signpost top section is mounted flush with the support tube thereby permitting the separation of support tube and signage. This separation makes it easy to assemble and disassemble signboards and support tube and also simplifies storage.
