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

A stick in the bottom of the door would do the same thing, but I do feel a bit more secure. My patio faces a moderatly busy road. I'm sure it says somewhere on the product details, bit you do need a drill (1/8 bit) to install.

It was extremely easy to install and now I feel more secure.

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.

My initially received Securityman security bar set has been probably defective, but I did not realize it. I thought it is “you get what you pay for it”. The small issue with it was that the latch did not always hold the inner bar out, after the bar was being lifted (put in vertical position). However, the lock was pretty reliable and it worked that way well for a couple of months. Until the inner bar got stuck with the latch suddenly stopping working.The Product Support button on Amazon brought me the link to the Securityman Web site. The Customer Service agent responded momentarily and immediately emailed me a link to the RMA form. Few days later I have received my replacement.This time everything was fine: the latch was perfectly holding the inner bar in place in both modes - working and lifted ones and the lock was stable and reliable.My sliding door is not wide enough so I did not use the extension bar, but I have no doubt that it would give me no troubles if I needed it.Overall, I recommend the product: the quality is good and support is outstanding.

I see at the bottom of the page is an address for Ontario, CA, but I don’t believe it. The English on all of it is choppy, and has several typos. The biggest problem, however, is this: NO STEP BY STEP INSTRUCTIONS ARE PROVIDED! It tells you nothing about how to add the extension bar OR the end caps. They don’t click in easily, do I force them in? I ended up having to use a hammer for the extension bar, and slightly bending it. It also said “attach one end of the pre-drilled end caps to the End of the SECURITYBARPD (wtf is that?) and then screw the bars together using the threaded screw rod.” And how do I do that? I have no idea how the end caps are used in this scenario…but wait! Do you put the end of the instructions from two paragraphs ago with these instructions to find out? Maybe! Idk, I attached them together somehow, but it does NOT feel strong or secure at all. In fact, just lightly jiggling it with a fingertip makes it rattle a lot, and there’s too much movement. I also used a 3/32” drill bit because I was going to be screwing the screws in by hand and the 1/16th would have made me use too much effort. The instructions for how to install the lift lock and saddle CATCH (called a mount, and shown already together on pg 1, were also not very practical. When was the last time you held two separate pieces (lift lock; saddle mount) lined up and together with one hand, then extended the opposite bar over to that edge and set into the saddle, held all 3 of those separate things lined up and together one-handed while you grabbed a level with the other, and with your third hand (and your off-hand, to boot) grabbed a pencil to mark where to drill the holes? Then held all 3 of those loose parts together and lined up again while grabbing a drill to drill tue holes? Is there a particularly good reason why the saddle mount and lift lock aren’t ALREADY one piece? There should 100% be far more than 2 steps with an intro paragraph in MUCH larger font (since you won’t have a 4th hand to hold it up to your face). Step by step instructions aren’t supposed to be paragraphs; that’s your first clue that you’re putting too much together at once, then also doing it out of order doesn’t help. There’s also not a single link to an instructional video anywhere, so if you don’t already work with your hands assembling things all the time, you really aren’t going to be able to intuit how to get this put together.

Walked outside to grab something real quick, but must have not pulled this bar all the way up, so when I closed the door it slid back down.I couldn't open my door, so it did it's job. You would have to break the glass to get through this door with this installed.

I’ve ordered the bar for my patio door for extra security. It id adjustable to fit to my door, so installation is easy. Material is quality iron tube, so I think the bar is durable and strong. It looks nice on my door.
