Oldcastle Infrastructure FAQs
How do I know which Carson lid I need?
Measure the inside opening of the box (the hole the lid drops into). Common sizes: 6" and 10" round, 910, 1220 jumbo, 1419. The number is often stamped inside the lid.
Can I buy just the lid?
Yes — most of our Oldcastle listings are lid-only. Box-and-lid combos are labeled as such.
Green vs tan lid?
Green for turf. Tan for decomposed granite, desert, and some hardscape. Function is the same; color is the finish.
How fast do Oldcastle orders ship?
