I am trying to figure out which part to purchase. The numbers that are marked on the slider do not match any of the ones you have listed. See photos. Markings are 29 C

Hello there!

Thank you for reaching out to us. Can you confirm if your top fitting is originally wingless like the 19-002? If it is, take a look at the S351-30 or S390-30 channel balances. The difference between the two is the depth of the bottom shoe; you'll have to measure as shown below to determine the best match. 

Your 29C stamp may translate to the 2930 stamp option. A pair of balances with the 2930 stamp can support a sash weighing 16 to 23 pounds but you can weigh the window sash to confirm it falls within this range.

Please let us know if you have any questions!

I recieved my order (3009178) and the channels I received are 35 inches in length. I need the  channels to be 30 inches long How can I get these exchanged?

I am afraid we don't offer exchanges but you can start your return by going to this page here. You will then have to place a new order for the proper balances.
