About
REPLACEMENT EXTENDED TRAVEL WINDOW BALANCE – If your sideload window sash slams shut, won't stay in place along its full range of travel, or feels loose, this Series 320 Extended Travel Apex balance restores smooth, controlled movement across the sash's full travel. This window sash balance and pivot lock shoe pairing is the correct replacement for tilt windows that need to tilt in for cleaning.
EXTENDED TRAVEL BALANCE SYSTEM – Engineered for windows that need more travel range than a standard block and tackle balance, this balance uses the same spring-and-pulley principle to counter sash weight while preventing the sash from slamming shut or falling unexpectedly. As a window balance spring replacement built for extended travel, it is engineered to outperform a generic window springs replacement across its full range of motion.
BUILT FOR CONSISTENT PERFORMANCE – Rated 7 to 9.99 lbs for this stamp, the balance is sized to match your existing sash weight, and supports a tight seal when the window is closed to help maintain temperature control. This window channel balance construction is rated for consistent daily use with your pivot lock shoe.
MEASURE BEFORE YOU ORDER – This balance measures 20" long (metal channel only) and is stamped 19-2; compatibility varies by window manufacturer and model, so confirm your channel depth and length before ordering to avoid a return.
WHAT YOU GET – One Series 320 Extended Travel Apex balance with an overall length of 20" and a rated capacity of 7-9.99 lbs for stamp 19-2, guides pre-assembled; sold individually, other hardware not included.
