• A lower price
• Significantly reduced operating forces
• A substantial reduction of on-hand inventory with dramatically smaller space requirements

Our revolutionary, patent pending design allows for a quiet and tighter fitting sash. The system utilizes AAMA qualified springs and provides for a simple conversion from block and tackle.

The Curve Balance System

            Unlike traditional balance shoes that have four corners and are rectangular shaped, the NEW Curve Balance System is configured to have only one point of contact as the sash is raised and lowered. This revolutionary design reduces friction and drag. The result is lower operating forces and a smoother working window.

Assembling the spring to the Curve balance shoe is easy and does not require a screw. Completed assemblies are also available.

The Curve Balance System has a great price. Please contact us for pricing information and samples.

 

 

 

 

 

AAMA

            John Evans' is a member of the American Architectural Manufacturers Association. Our balance springs are AAMA qualified.  This includes our 8 lb. & 9 lb. 1/2" wide springs and our 10 lb. & 11 lb. 3/4" wide spring.  We believe we are the only manufacturer to have these 40” long springs AAMA qualified.
