Channel Balance Half-Inch length?

Thanks for posting. If the metal channel is indeed 36-1/2" long, not including the nylon fittings, then I am afraid neither the 36" or 37" channel balances will work for you. Instead, you'll need balances with that exact length. We should be able to provide this for you via custom order. I am looking into a quote for (4) Series 390 balances, 36-1/2" in length, and with the corresponding stamp option. I'll get back to you as soon as I can with more information. 

If you want to return the standard balances you purchased, see our Return Policy here. 

Before we proceed further, can you show me pictures of the nylon fittings at both ends? I just want to be absolutely sure you're dealing with a Series 390. You'd be surprised what variations there are with these balances. Assuming it is a Series 390, I have a quote I can then send to you. Many thanks.
