Keeler or KBC locks were used on Airstream, Argosy and a few other brands of trailer.
If the torsion spring under your handle is weak, rusty or broken, you can use this kit to replace it and bring a new feeling to your lock again. In addition, we include 7 stainless steel screws to refresh the old screws on your lockset.
The spring is made by hand in small quantitites in the United States.
