Telescopic rod: adjustable length, punch-free installation, suitable for renting or temporarily. Single rod/double rod: single rod hangs one layer of curtains, double rod can hang gauze curtains + blackout curtains simultaneously. Track rod: pulley design, suitable for heavy curtains or large windows (such as floor-to-ceiling windows). Decorative rod: with carvings or metal materials (such as brass), suitable for retro and light luxury styles.Selection suggestions: Select telescopic rods for small windows and track rods for large windows. Double rods (gauze curtains + blackout curtains) are recommended for bedrooms, and decorative rods can be used in living rooms to enhance the appearance.

Key points for measurement: Pole length = window width + 15~30cm (extended on both sides, showing a large space). Installation height: 10~15cm higher than the window frame (visually raise the floor height). Installation steps: Locate the punching point (use a level to ensure balance); Insert the expansion tube after drilling (critical for load bearing!); Fix the bracket, hang the rod, and test the stability. Common mistakes: Failure to use expansion screws leads to falling off; The rod is not long enough, and the curtain cannot be fully opened.

Short-term solution: Add intermediate brackets (support point spacing ≤ 1.2 meters); Use transparent nylon rope to assist in hanging. Long-term solution: Replace with metal track rods or thickened telescopic rods; Choose distributed hooks (dispersed force).

Metal rod: Wipe with neutral detergent + soft cloth to avoid scratches with steel wool. Wooden rod: Wax regularly to prevent cracking, and use a dehumidifier in humid weather. Track groove: Vacuum and lubricate to keep the pulley smooth.
