MH-Equipment manufactures this grip knob tool from high grade aluminum alloy which is then anodized to help prevent corrosion. This spanner tool keeps the adapter nut from distorting due to the use of an improper wrench. A retaining clip keeps the spanner in place while in use. This wrench fits all our AN-800 (7/16) style adapters 3 inch and longer. Weighs 1.7oz.
This wrench allows you to quickly and securely service all those hard-to-reach oxygen filler ports on aircraft out on the ramp.
