I am looking to replace both the window balance and the tilt lock shoes that match up with these.
The windows are a double pane, double hung vinyl window that could be the original windows from when the house was built in 1994. I don't know the history of them. This window measures 47" x 47" for the full frame.
The markings that I can read on the balance are "20H" "B.S.I." and what looks to be a small "PV". The balance measures 20" in length and uses a hanger at the top end to attach to the windows sill. In my sill is an opening in which the hangers hook into.
The shoes are a tilt lock type, measuring 2"H x 1-1/4"W x 1/2"D. That counts for the plastic piece, but the metal locking mechanism does protrude out from the plastic about 1/16".
I would have submitted a picture of the show outside of the sill, but I will need to cut it to remove first and wasn't ready to take that step until I knew I could get replacement parts. Please let me know what additional details I can include to help further identify my parts.
