Just bought this home and have vinyl replacement windows. Have to replace some of the counter balancers. I'm pretty certain it is a coil constant force. The spring is a series 160 from your website, but would like to buy the assembly...coil spring its housing & shoe. Can you help me?

The Series 160 Balance Coil can be inserted into a slot at the top of the 15-111 Pivot Shoe, then to lock it in you just twist. It is recommended that you remove both pieces of hardware from your application before you attempt to connect them.
