Failed tilt window hardware

Hello, thank you for posting,

At first sight, your pivot shoe does resemble the 15-228. The original will need to be removed to compare dimensions to confirm.

Dimensions for 15-228

This shoe is compatible with the 1/2" thick Series 160 or the 3/8" thick Series 165 coil springs. You will need to measure the thickness of the original spring and review the springs for any numbers stamped into the metal to confirm the weighted option needed to support the window sash.

Once the series is determined, take a look at the product page for compatible covers. 

If there are no markings, please provide the weight of the window sash to move forward. Thank you! 

Thank you,

The 15-228 measures just over a 1/2" thick at 17/32". It would be best to remove the shoe to fully confirm.

As for the coil springs, see the 1/2" thick Series 160 coils. If the springs are marked with a 9, you will need the S160-09 coil springs. If the window uses four 9 stamps, the total sash weight should be 36 pounds. If you are not able to read the inner coil stamp, I would recommend weighing the sash to confirm this weight. 

Also see the 15-150D double support cover. Let us know if you have any additional questions! 

Great!

You can use (2) S160-09 coil springs on each side to support the window sash. Let us know if you have any additional questions!
