Needing replacement part for coil spring with plastic housing

Hey there,

Thanks for reaching out to us! This coil balance spring appears to be either the 1/2" wide Series 160 Coil Balance (S160-04) or the 3/8" wide Series 165 Coil Balance (S165-4). You'll need the to confirm the width of your coils to determine the correct series.

Be sure to double check the stamps on each coil to ensure they are all 4lb coil springs. The plastic covers for these coils can be found in the related products for each coil.
