Metro Series sliding windows use the sliding door frame but have smaller sliding panel rails, interlocker stiles and mullions. Stiffening boxes on interlocker stiles and mullions are flush in the closed position.

Wide formats are possible with a maximum of six panels — two stacking towards one jamb and two stacking the other way.

For best overall performance, pair with The AGP System® with Solux-E® or Solux Ultra® low-e glass.
