• Cam Lock action draws sashes closer together for positive lock.
• Interlocking Meeting Rail: Integral interlock provides additional security.
• Heavy walled PVC framing acts as a natural insulator
• 3/4″ Insulating glass provides optimum energy efficiency
• InnovativE® high-performance glass utilizes Low E coating specifically engineered for local requirements
• “Warm edge” low conductance spacer resists energy flow through the edge of glass

NOTE: Full 3-1/4″ jamb depth chambered frame for maximum structural integrity. Comes with a double-wall, integral “J” channel designed into the frame, eliminating the cost of an add-on “J” channel while providing a pleasing “beveled” exterior look.
