Hi there:
Length is 21", not including the plastic end parts; stamped on the channel balance: 2030 (lengthwise), BSI (width wise), ND (length wise).
If you can identify them from this information and pictures, I like to order 2 of them. Also let me know what the price is of these items
If you have questions or need more info/pictures please let me know.
Thank you!
Rien
