Key item features

  • ENGINEERED FOR HEAVY-DUTY NON-TILT WINDOWS: The Amesbury Series 400 delivers superior load capacity and strength for non-tilt, side-load windows. Compatible with vinyl, aluminum, wood, and fiberglass frames, it fits most standard 5/8″ channels. This product measures 18″ in length, stamped 1740 and supports (14-19 lbs) lbs sashes. Designed for replacement and new installations, it ensures smooth, stable operation even in heavier window systems.
  • HEAVY-DUTY PERFORMANCE & PRECISION: Built for demanding residential and commercial applications, the Series 400 features reinforced pulleys and springs for enhanced lifting power and smoother motion. Its premium Amesbury engineering provides greater weight support and long-lasting balance performance than standard models.
  • DURABLE CONSTRUCTION & READY TO INSTALL: Constructed from heavy-gauge galvanized steel, the Series 400 resists rust, corrosion, and bending that cause cheaper balances to fail. Reinforced pulleys and precision springs maintain smooth lift through thousands of open-close cycles, keeping windows operating like new for years.
  • AVAILABLE IN LENGTHS FROM 10″ TO 55″ (3–65 LB RANGE): The Series 400 family offers one of the widest size and weight ranges in its class. Each balance is precision-tested for reliable lift and long-term durability—from light residential sashes to heavy commercial frames. Pre-assembled with non-winged top and bottom guides for quick, secure installation. Sold individually; accessories not included.
  • 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.
