Plastic Plaster Ring (For Poured Concrete)

[Features]
· A dedicated type for use when working with pouted concrete. Minimizes the amount of unhardened concrete that gets in.
· The surface of the plaster ring has been given a textured finish to prevent the concrete from peeling off.
· Can also be installed to plastic resin square concrete boxes manufactured by Mirai Industry.
· Allows equipment mounting positions to be adjusted, even after the concrete is poured and even if the box is slightly tilted. (Except OF-11PK)
