Adding extra security to sliding doors and windows doesn’t have to be complicated or expensive. This adjustable metal security bar, made from sturdy 1-inch diameter white painted steel, holds up to 400 pounds of force while fitting tracks from 17 to 50 inches.

Whether childproofing high windows or securing vacation homes, the bar allows ventilation while blocking forced entry.
