For about the cost of 1 glow plug, you can keep your good used ones protected and organized so you can find it when you need it. Loose plugs rolling around in your field box can accumulate dirt and grit, when you later use the plug you introduce this trash to the inside of your engine. This caddy stores up to 9 glow plugs. Injection molded from a brightly colored sturdy rubber like plastic material. The CADDY measures only 2" x 3" and does a big job for you.
