SECURITYMAN Sliding Door Security Bar-Child Proof Sliding Door Lock Bar with Anti Lift Lock - Fits Most Doors & Windows - Adjustable Patio Door Security Bar (18.75"- 51.1") Chrome

Many times I have put a cat-flap insert into a sliding glass door and bought a drop bar security lock so the door can still be quickly and easily locked, only to find the bar is jut a bit too long for the space remaining after the cat-flap insert is in. Then you have to install something at the top of the slider, or bend and move a dowel in the track every time you go in/out. Not so with this lock! It has a very adjustable length, even quite short if needed, and I was able to get it installed perfectly. Installation was easy, I put it in myself (female, 60) using my cordless drill/driver. I did not trust the adjustable black piece to hold the lock enough to prevent beak-in, but that was easily addressed by drilling a small through both overlapped metal "tubes" using a bit made for metal, then adding a set screw that fixed both tubes together, to make it even more robust. I actually added two set screws for good measure. And I put a little wire loop on the wall where it raises when open, to hold it when it's in the up position, so we don't lock ourselves out by the bar accidentally falling after closing (it hasn't yet, but it will become looser with use). My pro tip: if you are also using this with a cat-flap insert: go to the home improvement store and buy a roll of black EXPANDABLE foam weather strip to put on the vertical surface of the cat flap where the original slider door rests against it. The expandable weatherstrip comes in a fairly flat roll but when unrolled it expands. I got the .5-inch size and it was narrow enough to go on the insert yet absolutely perfect to allow for variations in the vertical surface. No gaps! The compressible weatherstrip plus adding a set screw to this bar lock also allowed me to get a very tight fit between the bar and the slider, making it very secure against anyone trying to wiggle it loose. If you have a 6-foot-wide sliding glass door, this lock will fit even with a medium size pet flap. So, I highly recommend this product.

Heavy duty bars. easy to use. Love the safety latch on bar easy to install. Highly recommend product.

This was basically an easy product to assemble and install. However, the hinge point where the tubes extend to accommodate the door width is a bit flimsy and could be built more sturdily. But even with this, the function as intended works well and should provide the desired security. Also, and perhaps specific to my door, the three screw base where attached to the door frame does not fit flush to my door and is only able to be secured by two of the three screws. But the attachment is tight and secure and will not pose any security or attachment issues. A good produce for the price point.

This is a bad design and was cheaply fabricated. It is very flimsy. The bar is too short to work without the extension and is too long with the extension. The designer was bad at matb so the bar will not work for some door openings within the advertised range without adding a 1" wooden shim. The clip that prevents the bar from sliding to a shorter length does not always work, sometimes it collapses without depressing the clip. The black plastic foot at the end that fits into the retaining bracket is about 3/16" too small. The dimples in the rotating bracket that hold the bar upright when the bar is unlocked are easily sprung too wide which will allow the bar to fall into the locked position thereby locking you out of your iwn house. Fortunately the bar is so flimsy that a few strong pulls will defeat it and allow reentry if it locks you out. The rotating bracket is wobbly so the bar does not pivot in a smooth arc. The rotating bracket mounting surface is about 1/4" too short so the bar partially blocks the mounting holes thereby making it hard to use longer screws that would actually engage the wall studs. This is not nearly as good as the one I bought for a previous house. This will just be a temporary supplement to the broomstck in the track until I have time to fabricate something better and stronger.

This is strong and made of good quality. I can rest at night now. Easy to install and easy to use.

Does it work? Kind of. Poor construction and weak materials on this device means it won't last long. Even the screws are thin and substandard for a "security" product. My suggestion is to find a product with higher quality.

Easy to install! Works like a charm.

Installed to my sliding glass door and is easy to operate and keeps the door locked and secure.

This was an easy installation. Unlike other security bars, it is adjustable to fit a smaller opening. It fits well and the security tab creates an extra step to lift the bar to enable the patio door to be opened. It seems to be well built and we feel more secure with it in place.

Tengo una puerta triple abatible, la estabilidad del producto era practicamente inexistente. Sin embargo el proceso de devolución ha sido hasta el momento sencillo

Sliding doors are not known for high quality locks and sometimes, as in our development, some keys fit many doors. Easy to install and use. Great break-in deterrent!

It installed fairly easily but I did make one mistake which I was able to correct in my workshop. I’m not sure that it is as sturdy as it should be but it should work well.
