The Partskeeper from Ranger Design saves plumbers time and the hassle of carrying several boxes, as all small parts and pieces can be stored in one carry-along kit. Save time by filling it at the end of the day, and be ready for service calls the next day, with all most-used parts on hand. It is lightweight and easy to carry with its practical handle, providing the advantage of carrying several items without dropping them. It can be stored in a van individually, or stacked by four, and up to eight in a cabinet. 800/565-5321; www.rangerdesign.com.
