DIIG Sliding Door Security Bar, 17.7-50.5inch Heavy Duty Adjustable Sliding Patio Door Lock Bar with Rubber Tips,Diameter 1inch Window Security Bar for Home Apartment Travel Children Women (White)

Works great on my sliding patio door. Feel a little safer now. Easy to use, install and remove on a daily basis and still works great.

When I started researching these I didn’t realize how many options there are out there! This one perfectly met our needs. We have various size sliders and it works for all of them with a quick and super simple adjustment. They’re very fast to install and give you that extra security comfort when they’re in place. I love that they come in black so they blend in with our slider base and you can’t even tell they’re there. Great quality and value!

Very strong, once adjusted properly it is very easy to use and remove as needed. The metal is strong and thick enough to withstand force. Flat black in color. Once the door is closed and this is inserted, it will not give. Overall length is fully adjustable, its just a matter of getting your bar set up the first time, then a breeze from there!

It’s a lot for functional than my usual piece of wood. Easy to use

Very good , but would prefer something I don’t have to bend down to the floor to put in place👍

Fits perfectly, lets me keep my sliding door open just enough to get fresh air and my cats can go in and out without me having to open it each time. Nice and sturdy and adjustable.

Love it.. perfect fit.. love the options of size doors this security bar can fit.. happy with it.. easy to install.. works awesome

Pretty much all security bars have regularly spaced notches you can extend the length to. This means you can't dial in an exact width and usually have to go a bit over, and put the bar in slightly diagonally. But this bar is really great because one end is a threaded bolt you can adjust to the exact length you need and then tighten a nut to get it just right. It has the notches like other bars, but once you are near to your desired width you can dial it in easily with the bolt and nut. Build quality is good and it feels quite solid. It also has a pin you can insert behind the main notch adjustment pin, which keeps the bar fully extended even if that first pin is somehow pressed down or fails. Whoever designed this thing knew what they were doing. If you have had issues with security bars that never fit right, or dropped out of place, etc., you want this one so you can get that fine adjustment going.
