Standard Interlock

This section shows where the sliding panels meet. The interlock decides how slim the sightline looks, keeping the frame to a minimum so the glass takes centre stage.

Triple Track Frame

The three rail frame adds an extra sliding panel. More panels can stack behind each other, which opens up an even wider gap.
