Need 2 Window sash replacements mark 28C winged

Hello,

Your balances look a like they could be either our  S380-29 with a 1" shoe or our S385-29 with a 1-3/32" shoe.  Although, there is a chance that it could measure 7/8".

To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe.  If the shoe does measure 7/8", please let me know as these will need to be a custom assembly.

You'll need to select the 2830 stamp option for a sash weighing 16 to 23lbs.

Comparison of the S378, S380 and S385 balance shoes.
