The SideLoad Constant Force Balance System

            Introducing a new option for side load windows.

Manufacturers finally have a choice of balance systems. Compared to block & tackle, the NEW SideLoad Constant Force Balance System offers:

• 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. We haven't forgotten the astetics either. The sash locks are currently avaiable in 3 colors; white, ecru and sage. Click HERE to view.

The SideLoad Constant Force 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.
