Dixon® Air King™ Heavy-Duty Safety Pin, 0.058 in Diameter, 1-3/4 in Length, 3/8 in Width, Steel, For Use With: Chicago Universal Couplings, Packaging Quantity: 1 PK
The use of an Air King safety clip or wire type retainer is necessary to ensure couplings will not become accidentally disconnected
Use of supplied safety clip guarantees the fittings are properly connected because the safety pin will not go through the holes in mating fittings until couplings are locked in place
