Top Guide, Bottom Shoe, Sash Guide, Cam Lock

Question

Looks a lot like the Series 390, with some minor differences.

Please confirm what parts I should order.

Thanks, Bob

The Series 390 will not replace this balance. You have a special type that has to be specially made. Before we begin, can you tell me the stamp printed on the metal channel? Can you also tell me how many you need?

For the top sash guide, see our 18-171. I don't recognize that lock. It's similar in design to our 90-072, but I'm not sure if this will work. Look it over and see what you think.
