Key Features

REPLACEMENT WINDOW SASH BALANCE FOR NON-TILT WINDOWS – If your double or single hung window won't stay up, drops on its own, or feels heavy to lift, a worn block and tackle balance is often the cause; this Series 300 balance restores smooth, controlled sash movement. This window sash balance is the correct replacement for sideload, non-tilt windows needing extra travel.
SPRING AND PULLEY SYSTEM – A weighted spring inside the metal channel works with an internal pulley and cord to counterbalance the sash, holding the window open at any height without a prop. This is a genuine window balance spring replacement, not a generic window springs replacement kit, so it restores factory-matched performance rather than a universal fit.
5/8" METAL CHANNEL CONSTRUCTION – Housed in a 5/8" channel with a spring rated 20 to 25 lbs for this stamp, matched to the weight of your existing sash for consistent, long-term performance. As a non-tilt block and tackle balance, it is built for consistent daily use across its full extended travel range.
MEASURE BEFORE YOU ORDER – This balance measures 26" long (metal channel only) and is stamped 25-4; 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 300 block and tackle balance with an overall length of 26" and a 5/8" channel depth, rated 20-25 lbs for stamp 25-4, guides pre-assembled; sold individually, take-out clips and other hardware not included.
