Designed for the budget minded medical professional. Our basic kit can carry a steel "D" , aluminum "D" , or jumbo aluminum "D" bottle. The mesh pockets built into the lid can carry gloves and supply tubing. The generous outside pocket is large enough to fit a bag valve mask and V-vac suction device, as well as oral or nasal airways, which can be organized in built-in elastic keepers. The outside of the kit is built with casting® nylon for years of dependable service. Add a #10 coil zipper “quick open” top, our fluid proof grab loops, and you’ve got a kit that will give you years of faithful service. Recommended for first response use only. Not for daily ambulance duty. O2 tank shown not included.CTBOK1
