I'd like to start by mentioning that the pivot shoe you have been using has been discontinued. I highly believe the depth of your shoe is between our 15-121 (9/16" thick) and our 15-047 (5/8" thick) Being a residential window, I would lean toward the 15-121. Take a look and get back to us with some thoughts. |
