Adjustable Length
After choosing the size that best fits your space, expand or retract the rod to achieve the amount of tension needed for a secure fit. Holding the rod in both hands, easily expand it by twisting the right side towards you and the left side away from you. Continue to twist the rod until it’s longer than the opening by 1 or 2 inches (depending on the size), then pull it back to create tension and slide it into place. This will ensure a tight fit.
