A sliding window frame where the window panels (shutters) slide left or right on rails instead of opening outward or inward.

2 track” means the frame has two rails/tracks:
• One track for each sliding shutter
• Usually 2 panels (one can slide over the other)
• Maximum opening is about 50% of the window width.

60×46: This is the window size (usually in inches in India unless specified otherwise):
• Width: 60 inches (≈ 5 feet)
• Height: 46 inches (≈ 3.8 feet)
• So the window opening is roughly: 1524 mm × 1168 mm
