28 x 38 inch double hung window

A quick learner from Toms River, NJ says:

Good afternoon,

Not sure how many coils for this window. About 21 years old, vinyl replacements. No markings found on either top or lower piece or the spring. I would guess single coil. Spring width is 0.5 inches, lock / lowner end has a 'T' and a round 3/16" hole about a half up the coil. Would prefer to replace the entire assemblies.

Thanks, John

Hi, John.

We don't sell this exact pivot shoe but we believe you can use the 15-228 pivot shoe which is compatible with the 1/2" Series 160 coil springs. For a new single coil support, see the 15-150S . Review the specifications for these parts and see what you think. 

To know what spring weight you'll need, check the band of your old spring for a stamped code.
