This looks like a version of our Series 775 we see from time to time. Confirm the metal channel length? If it's 24", you'll need an S775-24 with a stamp option of 24C. Measure the size of the bottom wedge shoe to determine which size you need. Note that with this replacement, you'll need to drill a hole in the window jamb to secure it, since it screws into the jamb rather than using a hook like your old balance. |
