Slideback- Sliding Door Closer (Heavy Duty Plus) for 8 ft Wide or Tall Doors

I have a heavy hard to open slider door. I installed this on a 6 ft. double sliding door. 36 in. each door. i only open one side. i needed to get this due to Queen Creek AZ requirement to have self closing and locking slider doors when you put in a pool. I mounted the unit for one door and put the unit in a pre-load position. example, I pulled it out about 2 ft. then screwed it in. i found it had more pressure to pull it back if you pre-load the closer. It closed it OK. make sure you use silicone spray on everything. it helps alot.

We needed a self closing sliding patio door for a pool inspection. Ours is a large, 8' door and new, so I thought I could surely bypass the need for silicone spray. Wrong! The installation went fairly well, but just like previous reviews reported, it did not close the last 6 inches. We cleaned the track, adjusted the speed of the mechanism, and played around with it for a couple of hours. Finally I purchased some silicone spray, sprayed once along the bottom & top tracks, and adjusted to the fastest closing speed. Voila! It works perfectly.

Edit: after having installed for a few days, maybe baking in the sun or just getting stretched out, it started to close to 3 inches, then it finally started to close all the way. without any assistance or secondary device to assist. The door does not slam closed, which is good for kids, but it makes it more challenging to open overall and it also starts to close immediately upon release, so you have to hold it open as needed (which is good for my situation). Changed to 4 star since it does work, just had to give it time. Original: Our door is super easy to open, can flick it open with your pinky finger (new wheels, aluminum door on a very clean track, not ideal to open so smoothly I might add, but it does). I have 6 kids and a backyard designed with them in mind, with that said, i needed something that would close the sliding glass door automatically since they always leave it open (bugs, rodents, a/c, heat, etc.. whatever the reason need be, want the door closed). It hooked right up, wasn't difficult, mounted with double sided tape as a pre-set before drilling. The pump adds a lot of opening resistance (which we actually liked because it makes it harder for the babies to open), however it fails to fully close the door. it doesn't really even come 'close enough' to closing, or I would deal with it even if it was just cracked open... but as you can see from the video & pictures, there is a good 6 inches worth of it being left open, it's not a gradual close at this point, it will just hang there until we manually close it - which this adds more resistance to closing beyond this point. Test 1: cleaned the track (even more-so than it was), no help Test 2: oiled the track up - no help Test 3: assisted push the door closed - it incrementally closed 1-2 inches until 1in left before resistance required a good 'push to close' Test 4: oiled up the top of the track (can hear some scraping sounds from wobble), no help Test 5: disconnected the pump to ensure I didn't mess it up, pump closes properly without door attached, door closes with flick as normal. Conclusion: I think this may be a good product, but just doesn't work for my application. I am not sure if I will keep it or return it, going to try a double resolve method... using this pump with one of those wire closer things at same time, see if the wire mechanism can give it that extra tug to close, and if so, then it will have been worth it, even if it took 2 separate items. if not, then i will likely return.

Guys, I was skeptical to buy this and unfortunately I was right. When it was delivered, the package was really light and not heavy at all. I knew right away this is not a good sign for quality product However I ordered heavy duty one due to my size of the door so it can push close and tight . I followed to instruction to install. After completed installation the door to failed to close completely even when I adjusted the speed . This thing is overpriced. I paid over $159 dollars for this and its not worth it more than $30 to my opinion .It may work on other doors but not on oak Anderson 400 series door. If you have a patio sliding door like mine please don't waste your time. Thank you for reviewing.

This is very pricey but it’s the only solution we could find to auto close our sliding glass doors. We live in an area with lots of coyotes, so we needed a solution to keep our cat inside. My kids are prone to leaving the doors open It works well, but there’s absolutely no reason this should cost 150 dollars. That’s highway robbery.

I’m giving this a full 5 stars because I want people to know it works and it works well, since it’s basically the only option on the market right now. But there are a lot of caveats. You need to be at least little handy to get this thing going. You also need silicone lubricant, which it does not come with. Your door also needs to slide easily. It won’t work otherwise. We have a huge trim on our door frame, but we were able to mount the bar on the underside of the trim and it fit great. Very happy with this! I’m not sure that it will completely prevent my husky from opening the door, but it will definitely slow him down.

I don’t normally write reviews but I have to for this one. I am building a pool and my county requires an auto closer for sliding glass doors if you don’t have a fence. I ordered the heavy duty as I didn’t want any issues. It worked fine for a week and then stopped working. Emailed customer service and they called me 3 minutes later. We went through some troubleshooting and ended up sending me a replacement and fixed the issue in time for my inspection. Do your due diligence. Clean the tracks completely. Dirt and animal hair will slow down your rollers. Replace your rollers if need be (quite easy to do) as old rollers will be rusty and will cause some drag. This isn’t a very strong ram but it will do the job correctly as you ensure your door assembly is in good working condition. The customer service and follow through are top notch.

We are having a pool put in our backyard and per city codes we needed to get certain door and window locks for safety inspection. We have a large double slider and needed to make it self close somehow. After finding out that it can get really expensive having companies come out and do these things, I started looking around to see what we can do ourselves first. Was able to purchase self close hinges, window hex locks, push pin lock, yard gate tension springs and even this! This was such an awesome big money saving find! Really know your door weight before ordering. I ordered a medium first and it wasn’t strong enough, I under estimated our doors weight. This one was perfect. Husband installed it easy and after cleaning tracks it was up. At first it does seem like its not going to fully work but after some opening and closing it will start to loosen up. We don’t have little kids in the house and thought of just taking it off after inspection, storing it to throw back on if we have little ones come over....but after using it we actually like it. It’s nice to not have to get up after some one forgets to close behind them and we have the other side to open if we need it left open. But it is so easy to pop on and off that you can take down whenever. This saved us several hundred dollars by installing one ourselves vs hiring companies to come do it.
