This Plastic Floor Mat Kit For 18 Inch Deep Tool Box is designed to line the bottom of compatible tool boxes and help reduce scratches and wear on both the box interior and the tools stored inside. Made from high-quality plastic, this aftermarket replacement mat kit includes two pieces and is built to cover the floor of one tool box, providing a simple protective layer between metal surfaces and your equipment. It fits common 18-inch-deep tool box configurations, including sizes such as 18 x 18 x 24 inches, with additional options available for longer boxes like 30, 36, 48, and 60 inches. The durable plastic construction helps shield the interior from scuffs caused by shifting tools during transport while also helping keep the bottom of the box cleaner over time. Each kit is sold individually and includes a 90-day warranty covering defects in materials or workmanship from the date of purchase.
