Balance for late 1980s PGT no tilt 31"x50" windows

A home owner from Port St. Lucie, Florida says:

The metal channel measures 30"L x 9/16"W. The bottom bracket is non-winged 1 1/8". The top bracket is winged. The numbers on the channel are 29 3 E BSI. This is for non-tilt PGT brand windows for a South Florida patio enclosure probably from 1988. Thanks in advance for your help in identifying the best replacement channel balance.

Hi Harry,

Your balance assembly resembles the S395-30. Take a look and compare the specifications shown on our product page to yours. Also, you will need 2930 strength options for your replacement balances. Take a look and let us know if you need anything else. Thank you!
