Window crank with 11" arm

Question

I don't know who the manufacturer is. The hole pattern matches the 39044 configuration, but the arm is 11" long.

The number "40067" is stamped on the arm. The operator has threaded holes and is mounted from the backside (window frame has through holes).

The channel guide resembles 39504 and is 14" long.

What should be the dimensional relationship between the length of the arm and the length of the channel guide?

I need 2 right and 2 left operators, color black.

Can you please help me find appropriate replacements?

I'm afraid we don't have a version of our 39-142 that is back mounted, but you could circumvent that by using our 33-205 press-in nut. You just need to match up the appropriate screws with a 10-24 thread at your local hardware store.
