• Rollers (Wheels): Located at the bottom of the door panel, allowing it to slide.
• Track: The metal rail the door slides along.
• Multi-Point Locking System: A system engaging at numerous points along the frame for heightened security.

• Modification Screws: Hidden screws (generally near the bottom corners) used to raise or decrease the door panel.
