The 7019 is built for display spaces that are wide but shallow. Its double-sided board, only 320 mm deep, carries 36 pairs, and a half turn on its base brings the second face of 18 into view.
Optical practices place it along a waiting-room wall, at the end of a dispensing counter or between seating areas, where floor depth is limited. Patients see one face of the sun range and turn the board to see the other. Optical assistants can give each of the four columns to a brand, shape or lens colour.
Pharmacies use it at aisle ends and beside the counter, where floor depth is tight but a full seasonal range is still wanted. Gift shops, boutiques and department store accessory areas use it on plinths and low tables, often against a wall or window, with enough clearance behind for the half turn.
Holiday retailers and seaside stores, which often work in narrow units, also suit the format, since the board puts a full range on a narrow strip of counter or floor.
In each setting, staff stock both faces and decide how the four columns are divided, often keeping the busier lines on the face that looks onto the main walkway. Customers browse the face in front of them, give the board a half turn and pick a pair from the other side. The white header box on top finishes the board neatly, and the unpowered build lets it stand wherever there is a level surface and room to turn.
