Hello. I'm looking to replace the plastic coil spring balance covers on a relatives windows. The spring balance are completely functional but the plastic covers have degraded due to sun exposure. Thank you for your time. Mike

Hey there! Thanks for your question. If the coil springs are 3/8" wide, you can use 15-204 dual support cover. Let us know what you think.
