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 (Black)

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!

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

Works, but could be better. I gave this 4 stars because it dose work with some adjustments and will rub black rubber off when sliding into position. Best at top of sliding door so children cannot reach. I do like that I can use this as a safety lock for my 3 year old as she can open our door without this. I did have some trouble figuring out assembly just right, but worth the purchase.

I bought for security for my glass sliding door. After 2 weeks, the lock latch on the door broke, no way to prevent an intruder. Now I use this bar to secure the door until I can find a lock that will fit the glass sliding door. So far I have been unsuccessful, but I am not stressed out as this bar has been working great so far. This bar comes with an additional bar to expand if needed. To connect the bars, a simple twist connects the 2 pieces together. I did not need the expanded bar attachment. The rubber ends protect from scratching the frame. One end adjust to secure in place and removal. The bar is strong, doesn't bend, and has held up with daily use as I force in place. I use it without the drill in frame attachment. Overall, I am very pleased with this product and thankful it works securing my glass slidding door from opening.

All good, it fits. Seller shipped all parts correctly, on time. Prior question resolved--it's all there, and works fine (I had missed a part still in the box). Seller was very responsive. Good product. Yes, would recommend both product and seller.

Great price. Secure product. Just what I needed at a decent price.

This has been a solid addition to our home security setup. After installing it on our large sliding patio door, I immediately felt more secure—especially at night and when we’re out of town. The adjustable length made it easy to fit our door perfectly, and the rubber tips provide a snug grip that doesn’t scratch the track. Installation was straightforward and didn’t require tools, which I appreciated. The bar feels sturdy and holds firm under pressure; it gives good peace of mind knowing the sliding door won’t budge if someone tries to force it. We’ve also used it on a secondary window with good results. Easy, tool-free installation,Adjustable length fits a wide range of sliding doors and windows,Rubber tips provide solid grip without damaging surfaces,Sturdy and reliable for peace of mind,, It is not made of plastic material,, & value for money. But Heavier than expected, slightly awkward to adjust,,Cannot be used when door is fully open (standard for security bars),,Not visually discreet (function over form). Overall, this security bar is a reliable, affordable option that enhances home safety without a complicated installation.
