Window Balance

Question

I am looking for the part to replace the window balance. The following dimensions are approximate. The window channel is 30 inches long, 1/2 wide and 5/8 deep. It has a cable and spring system in the back of the channel. The marking on the balance says 30 with another number that I cannot read.

The window hold down measures 1" x 5/8 x 1 5/16 (total length).

The 1st picture is the marking on the balance.
The 2nd picture is the bottom of the channel.
The 3rd picture is the top of the channel.
The 4th picture is the window catch that is screwed into the top of the window
The 5th picture is a side view of the bottom balance that ties into the window frame.

Thanks for posting. We can replace this balance for you, but it will have to be custom made due to its unique design. I believe the stamp reads 30-3. Check an identical balance to confirm before proceeding. Note that these replacement balances have wings, or 'side tabs' on the bottom shoe. It won't make a difference in function, but I just wanted you to know so you're not confused by the difference. Assuming that all sounds right, I just shot you an email with a purchase link to order two(2) of these balances. Let me know if you have any further questions.

For the Top Sash Guide, start by comparing your old one to either the 18-166 or 18-009. Note that our guides don't have those side tabs, but I don't think they'll make much of a difference in function. Compare dimensions to both suggestions and see if you think either might work for you.
