29" Channel Balance for non-tilt window

The metal channel measures 29" long excluding the plastic parts that extend past the end. It is 9/16" wide. The top has a plastic insert with wings that catch in the channel and the bottom has a plastic ramp-like structure that tapers from approx 1/4" to 0" and is approx 1" from end to end.

Toward the bottom end it has a stamp that says 2810Z.

To me, it looks like your S370-29 (https://www.swisco.com/29-inch/pd/Series-370-Channel-Balances/S370-29) is the closest match but I wanted you to confirm this before placing my order.

Thanks for your help!
