Carson Brooks 254 mm (10-inch) Round Valve Box Lid

This genuine Carson Brooks replacement lid restores surface cover and maintenance access to a compatible Carson 910 round valve box without replacing the buried body.

Compatibility and construction

• For Carson Specification Grade model 910 only; nominal 254 mm (10-inch) round family
• HDPE T-cover with a slip-resistant, marked surface
• Designed for the matching 910 body; nominal size alone does not prove compatibility with another brand
• Lid only; valve-box body and any replacement fastener are not included unless expressly stated

Confirm the model marking and seating dimensions on the existing body before ordering. The manufacturer's 910 drawing shows a body opening of approximately 235 mm and an outside body width of approximately 298 mm at the top, illustrating why a nominal “10-inch” description is not a universal lid measurement. Use only as part of a suitable light-duty, non-vehicular box-and-cover assembly.
