Pivot shoe/coil

Hello, thank you for posting,

Your pivot shoe resembles the 15-191 heavy duty shoe that is compatible with either the 1/2" thick Series 160 or 3/8" thick Series 165 coil springs. Please review the dimensions below to confirm a good fit! 

Alternate image for 15-191

The original springs should have a number stamped on them that indicates the weighted option needed. If there are no markings, please provide the weight of the window sash to move forward! 

Compatible covers can be viewed on the coil series product pages once determined. Let us know if you have any additional questions.
