4 in Floor Cleanout
The Jay R. Smith Mfg. Co 4890 is a round floor cleanout designed for commercial and residential drainage systems. It provides a secure access point for maintenance on cleanout drains. The unit is constructed from nickel bronze with a bronze finish for corrosion resistance. It is supplied new and includes a 4 in spanner wrench for installation and removal.
Screw-In Installation and Load Capacity
This cleanout fits directly into a compatible cleanout drain using a screw-in connection. The round shape and 3 1/2 in overall diameter allow it to sit flush with the finished floor surface. The nickel bronze construction supports a load capacity of 2, 000 lb, making it suitable for areas with pedestrian traffic. The 6 in overall height provides sufficient engagement depth for a stable fit.
Sustained Load Performance
Under continuous static loads up to the rated 2, 000 lb capacity, the nickel bronze body maintains structural integrity without deformation. The screw-in thread design resists loosening from vibration or thermal cycling in the drainage system. The bronze finish withstands long-term exposure to moisture and cleaning agents. This product is not ADA compliant and is not intended for applications requiring that standard.
