I have a customer with double pane vinyl windows that have 22" balances. the stamp on the current sash is 2190. I removed one of the sashes and it is 35#. Do you have an option that will work in this application?

I would recommend the 2170 option, which we just added for you. This can carry a sash weight of 34 through 37 pounds.

This is a pic of the the top sash guide in the same windows. Am I missing something or does the entire sash need to be disassembled to replace this part? It appears that the lower screw is installed from the inside of the frame.

The bottom screw head looks like it has broken off. Unscrew the top screw and slide a screw driver under the top sash guide and then try to pop it off. You can then use a pair of locking pliers to unscrew the broken screw stem. The top guide itself looks like the 18-179.
