What is your matching part number for this item?

The channel width measured 0.557" (on the channel metal side) to 0.649" (on the channel open side that which has an stuck out edge).

Hello, thank you for posting,

With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. The length of the metal channel excluding the nylon attachments should measure 32" long and you will need a 3130 stamp option.

Please review and let us know if you have any additional questions!
