I need 14

Thanks for posting! It looks like you have either the S380-15 with a 1" shoe or the S385-15 with a 1-3/32" shoe. 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. You'll need to select the 1420 stamp which is rated for a 6 to 10lb window.

Comparison of the S378, S380 and S385 balance shoes.
