This channel balance is 17" long and 1/2" wide. The stamp reads, "16 4 HS CALDWELL".
We need at least 2; but possibly as many 6.

Hello to you and your feline fixers! We can definitely supply this balance. Start by looking at our S385-17 with a 1640 stamp option. These come with a 19-005 top nylon fitting and a 15-004 bottom nylon fitting. As long as those match up then I think it will work very well as a replacement.
