When we bought our 5th wheel, one of the windows had a damaged roller on one of the arms of the window crank. The other roller was intact and worked well.

This past outing, that sole survivor finally gave up and the window was flapping in the wind. Between my wife and I, we managed to secure the window prior to our departure using the nubs on the rollers, a bit of good timing and some luck.

I sourced a replacement at Pelland Enterprises for a decent price.

Apparently the scissor style is called a "Hehr Torque Operator" and there are 3 different sizes. Removal and install took less than 10 minutes with a properly sized drill to remove the rivets and then finding a short set of bolts and nylon locking nuts in my stash in the garage.
