Marvin Casement Style Dyad Roto-Gear / Truth EntryGard Operator - Designed for use on windows that are too narrow to accept the EntryGard Dual Arm Operators, this hardware can be used on windows as narrow as 11" between stops.  The result is excellent low-torque operation of narrow casement windows through a full 90° opening.
