Fuji Clean Septic Tank Lid Φ450, Load Capacity 500K Purchased from the construction company when the house was newly built in August 2024. The condition is good. It became unnecessary soon after due to exterior construction. A car has never driven over it, and I think there is almost no deterioration. Since there is sand on it, I will wash it and ship it after you purchase it. - Model: 500K - Size: Φ450 - Material: Plastic - Application: Manhole cover Thank you for looking.
