1/2" Constant Force Balance Coil Spring D, 6 Pound

This 1/2" (12.7mm) constant force balance coil spring, type D, is rated for 6 pounds (2.7kg) of sash weight. It is a standard replacement spring commonly used in single and double-hung tilt windows to help balance the weight of the sash, allowing smooth and reliable up-and-down operation. This coil is suitable for many vinyl and aluminum window brands that specify a 1/2" balance spring, making it a reliable solution for repairs or replacements requiring this size and weight rating.

The coil is priced and sold individually as a single spring (not as a pair). No additional hardware or mounting brackets are included; this listing is for the balance spring only. Please ensure compatibility with your windows by verifying the width, style, and weight rating before ordering.

  • Manufacturer: Amesbury Truth Hardware
  • Spring type: Constant force coil
  • For 1/2" (12.7mm) balance system channels
  • Weight rating: 6 pounds (2.7kg) per coil

Always measure your existing hardware and compare the spring's width and weight capacity to ensure a correct fit before ordering.

“Ordered a hard-to-find Pella handle set from the website. Handle arrived as promised and fit perfectly. It was listed as blemished but the chip was nearly invisible and on the exterior of a seldom used door. You saved me $450!”
