Im looking for putz 3 section cable remote box,{year 2000} pump didnt come with one when I got it. just for back up if ever my radio packs in

I would be tempted to talk to the remote company Omnex or HBC Which ever it is. They would have one or lead you to a good used one. Shouldn't be hard to find. We always have two radio and never use cables but sure you could find one locally. 

putz parts,they have the inside track

I would Call Lee Arquette at PMA Protec IE Refurb 800 890 0269. He might have a used one. Another guy at the same number would be Mark Skura in the remote repair dept.
