I replaced load balancers. Now with these new load balancers the window opens and closes super easily and stays open in place. It’s like new window! Installation was not difficult after watching some instructions on youtube. ### ⭐⭐⭐⭐⭐ Great replacement! *by J***N on October 9, 2015* Needed these to fix my old double hung tilt replacement window balances. I wasn't sure of the diameter (it measured a little under 1/2") so I ordered the 3/8". They are smaller than the originals, so they must have been 1/2 or 5/8 but the ends are the same so no big deal. The color of the ferrule is probably most important. They fit just fine, and the windows stay up after you lift them now, instead of having to use a prop rod. This was a great deal compared to other sellers if you order several. A tip for installation that made it much easier was to lift the window sash up to about the retracted height of the balance, clip the bottom in, and then to tension it just turn the tube a couple of times and screw it in at the top. No balance tool needed. Each window only took about 5 minutes to do both balances for the lower sash. The upper sash would probably be a little more difficult, but same idea. ## Frequently Bought Together - WRS Caldwell Series 50 3/8" Spiral Tube Window Balance for Tilt Windows - 29" Gr - Prime-Line H 3787 Tilt Balance Tension Tool, 10 in, Silver - Prime-Line H 3786 Window Channel Balance Shoe Set (1 Set) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/182141885-wrs-caldwell-series-50-insul-tilt-3-8-balance-29](https://www.desertcart.hr/products/182141885-wrs-caldwell-series-50-insul-tilt-3-8-balance-29) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-13*
