Featuring a secure sash that presses tightly into the frame when closed, this system cannot be manipulated from the outside, providing maximum protection from break-ins.

Eliminating the need for a frame in adjoining two panels, the Kenneth & Mock® Corner Butt-Jointed Window allows an unobstructed view while staying reliably water-tight and secure.

The fully-integrated lift rails ensure smooth gliding and the versatile design complements different house styles, from Dutch Colonial to Mid-Century Modern.

This archetypical configuration constructed using patented German profiles provides a hinged door that is the most air-tight and water-fast in the market today.
