When a window crank knob cracks or the lugs wear round, this JR Products replacement gets your window operating smoothly again. It's built for the common 9/16 inch tri-lug shaft found on many RV windows, and the included screw means you won't be left hunting for a matching fastener.
A quick, low-cost fix that saves you from wrestling with a stripped or broken window crank.
