The 4 piece heavy duty HVAC Package has two 3" sides, a small wiring tree with the 8" ring for nitrogen, and a three bucket end that has two 13" bucket rings to hold reclaiming tanks, and a 10" ring to hold a Freon tank. This leaves plenty of room for other tools and supplies. The wiring tree will hold wire, tubing, extension cords and other items often needed for installations and repair. This allows the worker to make one trip instead of many. Weight 37.5 lbs. Measures 52.5" x 29.75" x 40"
