These are left over from a project and are unused. I have about 15 of them left, so you can buy one, or buy them all. They are 3/4” wide and 3/4” high and are 6’ long. I don’t remember the terminology on gear pitch, but you can tell by the pictures what I’ve got. From memory, I bought theses racks and the pinion gears from McMastr-Carr. The racks ran about $90.00 each, and I am asking $40.00 each.
$40.00 cash only, local pickup or PayPal + shipping.
