Description

  • This Series 37 Triple Coil Spring replaces the three-coil internal spring set inside QuickTilt triple-coil housings. It provides 7 lbs (Stamped – 7GE) of calibrated lift per coil for heavy tilt window sashes requiring maximum support. Coil only—housing, pivot shoe, and hardware not included.
  • CONSTANT-FORCE PERFORMANCE: Made from premium stainless steel, each Series 37 coil delivers smooth, even tension through every sash movement. Unlike cord-and-pulley systems, constant-force springs reduce friction, prevent sticking or slamming, and maintain reliable lift for thousands of open-close cycles. Designed for long-term durability and consistent window performance.
  • EASY DROP-IN REPLACEMENT: Designed to fit directly into WRS Series 37 QuickTilt balance housings, these 17/32″ coils install quickly without special tools. Perfect for DIY repairs or professional maintenance. Simply match the stamped coil weight to your sash rating and replace coils on both sides for best long-term performance. Coils sold individually; housing and pivot shoes not included.
  • FITS SERIES 37 BALANCE SYSTEMS: Compatible with WRS Series 37 QuickTilt Single, Tandem, and Triple coil balance housings used in vinyl, aluminum, and wood tilt windows. Works on either left or right side interchangeably. Ideal for restoring proper sash lift in residential window systems where smooth, reliable operation is essential.
  • TRUSTED SINCE 1989: WRS Window Repair Systems has over 30 years of experience supplying reliable, high-quality hardware. Trusted nationwide by homeowners, contractors, schools, and property managers for dependable repairs and long-lasting performance.
