Conston Product Details:
The Secret Sauce
We use a special crowned stainless spring steel which we embed in the hem pocket of each fully retracting specialty shaped shade. This allows the hem to be stiff when the shade is deployed while also allowing the hem to be flexible enough to wrap the roller when retracting.
The Conston Spring Rail
The 2.2” deep x 2.7” tall Conston spring rail houses the multiple springs required to lift our specialty shaped and bottom-up shades. Type 301 stainless steel is used for the constant force spring while super-strong fiber cording made from ultra-high molecular weight polyethylene is used for the low visibility cording.
Precision Cutting
With every specialty shaped project we plot the window opening and then build the shade within it to ensure precise fitment.
