Adjustable Window Security Bar, Child Safety Patio Sliding Door Lock, Sturdy Steel, Extends from 16 3/4" to 44"

Key features

• ✅ STRENGTHEN HOME SECURITY - High-impact STEEL burglar proof bars are used to stop criminals from entering homes through open windows or patio doors. Windows can now stay open to the width or height you wish and be securely locked open.
• ✅ EXTENDABL & ADJUSTABLE - Decide how high you want the window to open with the adjustable settings. Lock the height in place with the push of a pin and the long screw help to reach the very small adjustment of the window's opening.
• ✅ STOP FORCED ENTRY OR UNEXPECTED EXCIDENCE - The Push pin provides extra resistance from forced entry. Burglars can't reach it from the outside when correctly installed. It can also protect children from falling out of open windows.
• ✅ NOTICE- PLEASE MEASURE the window or door track where the device will be placed BEFORE BUYING. The security bar extends from 16 3/4" to 44" long (MAX length is 3.66 feet). Window tracks MUST be at least 1 inch wide. The security device is 1 inch wide in all sides.
• ✅ EASY TO INSTALL - Unique design; No tools needed. Stick the supplied adhesive strips on the window /door track and the security bar and then put it on. It stays well and doesn't fall out when properly installed and adjusted. Removes easily in emergencies. Fits discretely in window / door tracks and looks decent.
