WRS Caldwell Series 300 Window Balance - 5/8" Channel, 24" Length For 15-18 Lb Sashes, Non-Tilt Replacement

About This Product

Hey there, dealing with a stubborn window that won't stay up? This WRS Caldwell Series 300 window balance is your solution! It's specifically designed for non-tilt, side-load windows with that standard 5/8\ metal channel you find in most vinyl and aluminum frames. This 24-inch model handles sashes weighing 15-18 pounds perfectly. The galvanized steel construction means it won't rust on you, and the spring-and-pulley system gives you buttery smooth operation - no more slamming or sticking! Installation is a breeze since it comes pre-assembled with top and bottom guides already attached. Just measure your existing balance's metal channel (don't include the plastic ends), make sure you've got that 5/8\ depth, and match the stamp number to your sash weight. Pro tip: always replace both balances in the same window for best results. WRS has been in the window repair game since 1989, so you know this is quality stuff that'll last for years. Whether you're a DIY homeowner or a professional contractor, this balance brings back that like-new window performance without the headache.
