Why use a folding warning plate?
A folding design is useful when a marking should only be displayed during certain operating conditions.
Folding warning plates are useful where a warning sign does not need to remain visible during every vehicle operation. The reflective face can be opened when required and folded away when the warning is not applicable, giving multi-purpose commercial vehicles a practical changeable marking system.

The hinge, locking mechanism and panel body are as important as the reflective face. A good mechanism should remain secure under vibration, stay closed when not in use and hold the sign flat and readable when opened.
Reflite can help select the construction according to the mounting area, panel type and frequency of use. The actual symbol or reflective layout should match the real operating requirement, and regulated graphics or dimensions should be verified separately.
Common technical questions about product selection, surfaces and application.
A folding design is useful when a marking should only be displayed during certain operating conditions.
The hinge and locking mechanism should remain secure under vibration and prevent unintended opening or closing.
That depends on the product design. Panel format and graphics should be specified for the intended operation before ordering.
