About this item

  • 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 8 to 13 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 34" long (metal channel only) and is stamped 33-1; 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 34" and a 5/8" channel depth, rated 8-13 lbs for stamp 33-1, guides pre-assembled; sold individually, take-out clips and other hardware not included.
  • WRS — TRUSTED WINDOW HARDWARE SINCE 1989 – Window Repair Systems has been supplying precision-fit window and door hardware to homeowners, contractors, property managers, schools, and commercial facilities nationwide for over 35 years.

FAQ

What types of products does FixTimber offer?

FixTimber offers supplies for repairing, reinforcing, sealing, weatherproofing, preparing, and finishing wood-frame homes. Our collections include wood repair compounds, adhesives, fasteners, structural hardware, exterior hardware, weatherproofing materials, finishing products, and repair tools.

How do I know whether a product is suitable for my project?

Review the product description, intended application, dimensions, materials, compatibility information, and installation requirements before ordering. If you are uncertain, contact us with details about your project and the product you are considering.

Are your products suitable for outdoor use?

Some products are designed for exterior applications, while others are intended only for indoor or protected areas. Check the individual product page for information about weather resistance, moisture exposure, temperature limits, and suitable surfaces.

Can I use these products for structural repairs?

Certain fasteners and connectors may be intended for structural applications, but suitability depends on the building design, load requirements, local codes, and installation method. Structural repairs should be evaluated and completed by a qualified professional when appropriate

Do products include installation instructions?

How can I choose the correct size of hardware or fastener?

Measure the relevant lumber, opening, connection, or existing component carefully. Compare those measurements with the dimensions and specifications shown on the product page. Do not select structural hardware based on appearance alone.

Will product colors and wood finishes look exactly like the images?

Colors may appear different because of lighting, screen settings, wood species, surface preparation, and application method. Test stains, fillers, waxes, oils, and coatings on a small inconspicuous area before completing the entire project
