Technical Specifications

Product Details

Product Features:

Eliminates the requirement of finger guard at the jamb– a component that consistently fails.
A folding pivot is subject to torsional loads and fatigue failure caused by
- location of the pivot point with respect to the alignment of the panels;
- flexing (twisting) of the door panels during normal operation;
- jerky operation of the drive mechanism.
Moving the pivot closer to the jamb provides additional support of the pivot and increases the clear opening of the door. The record bottom pivot is a sealed, precision bearing mounted into a hardened steel ring, which provides protection for the bearing. Being positioned adjacent to the jamb also increases net door opening and abuse protection.
