I chose the grills with hinges instead of stationary grills, which allows them to swing open and provide a window egress in case of an emergency. Written installation instruction were a little vague, but the accompanying pictures helped a lot. I did find that it makes it a lot easier to put up if there are two people to install them rather than just one person. I would suggest, however, using regular Phillips head screws instead of the one way screws that came with the product. That way, the grills can be removed if they are no longer needed. ### ⭐⭐⭐⭐⭐ 100% Satisfied. Easy to install. *by P***J on November 28, 2016* Superior quality, easy to install. Great safety device and opens quickly in the event of an emergency. The screws are one way screws that cannot be removed without a special tool. You may want to consider this prior to installation. Very heavy duty construction. ### ⭐⭐⭐⭐⭐ A little more protection *by R***B on January 25, 2025* We have basement windows and I purchased a couple of these for a little additional security. To lock it down i used a small master lock. Very solid! ## Frequently Bought Together - Prime-Line S 4776 21 In., White Painted Carbon Steel, Hinged 4-Bar Window Grill (Single Pack) - Segal S 4764 Fixed Window Guard – Adjustable Child Safety Window Guard Prevents Accidental Falls, Tamper Resistant Screws Included, Non-Egress, White, 23-1/2 to 38 In.
