Yale P-YSMDC-PC Concealed Door Closer, Fits into the Hinge, Automatic Closure of Doors Up to 50 kg, Electro Brass Finish

This is the only door closer that I could find which is invisible. Once fitted it works perfectly. But thank goodness for P Waldron's review which I had remembered reading when looking at the reviews before buying. His 2" nail method really works, but the difficulty, even then, with fitting is much worse if the door only opens to 90 degrees (e.g. if it is in a corner). Indeed I don't think it is possible to fit if 90 degrees is the maximum the door will open - by removing hooks on the back of the door, I was able to open my door to about 100 degrees and was just able to fit it. Perseverance is the key. I certainly dread having to remove the door again and I certainly do not intend to vary the tension which sounds so simple in the instructions but will entail removing the plate from the door frame.

I bought a pair of these to keep the doors to our living room closed and the heat in. The first thing I noticed is that it says on the pack you need a 26mm diameter drill. I thought I had a good range of drills but not this one. In fact, I went around 4 hardware stores and was unable to find anyone who even stocked a 26mm drill - it's an unusual size and if you need it you'll probably have to order off the internet. When I measured it, the barrel is actually about 22mm across, so a 25mm drill is perfectly adequate and much more common. Be aware however that drill needs to be longer than normal or you need to find a way to extend it so it can make a 150mm hole. I had two 25mm drills but both were too short so I needed to add an extension piece to do the last 10mm. Depending on the width of the doors you have, 25mm is still a big hole and I had to be very careful to drill a hole completely straight so as to avoid coming out on one side of the doors. Even so, the vibration was enough to cause a visible split on the inside of one door which I had to patch up afterwards. Both devices that I received came with the tension set to that I needed a screwdriver to separate the plates or rotate the plates. I was probably being thick but it took me awhile to realise that by simply rotating the plates anti-clockwise, you can release the tension so that the plates are easier to part. That said, the instructions optimistically tell you to pull out about 4cm of chain at one point without giving you a clue how to do that. The spring is extremely powerful and you won't be able to get even a cm pulled out by hand or using pliers. I found that the best technique was to fit the barrel into the door and then use a claw hammer to lever out the chain before using the provided retention plate to hold it there. After that, the rest of the fitting becomes straightforward. As a minor niggle, the quality of the screws provided was questionable. One had a malformed head and was useless and another head twisted off when screwing it in. The good news is that they work well once fitted. I just hope they last.

As previous reviews have stated, this device is excellent but the fitting is very difficult so be warned. An alternative that I have installed on other doors is the "Reilor C10 Gibcloser Auto Door Closer" which only requires x5 screws and took a few minutes to install so it depends on your DIY skills and requirements. My advice is to fully fit the main cylinder to the door by drilling a 22mm hole (as mentioned by Sam). The recess can be chiselled out by first fitting the device and cutting around the rectangular plate to a depth of around 3mm with a Stanley knife, this creates a clean recess for the plate. Adjust the device for the required tension in the chain by rotating the plate, anti-clockwise reduces the tension. I advise adjusting the tension at this point as you can see the device unscrewing at the other end, for which there is no end stop. As others have found, if you go too far the device will fall apart. It's also worth mentioning that I have a 3 year old so wasn't sure what the lowest tension would be, but I can affirm that it is fine and that the door doesn't slam shut but just draws to. Once the cyclinder is fitted the door can be closed to create an indentation in the door frame for attaching the chain retaining plate later on. Now for the bit that everyone has problems with, you will need something metal that will fit through the links to stop the chain from returning, I just used a small allen key but nail or similar is fine (as others have mentioned); in fact probably better as it won't bend your allen key. I preferred putting something through the chain as oppossed to using the supplied plate as it was less likely to fall out, and believe me, you wouldn't want your fingers near it if it goes! Attach mole grips to the metal bar at the end of the chain, pull it out as far as it can go and insert your nail. I had to hold the fat end of the mole grips and put my knee up against the door in order to apply enough force. As previously stated, this isn't easy and I do lift a few weights. Now all you have to do is cut out the recess in the door frame and attach the retaining plate. Voila! I hope his description helps as it really is worth the effort for this excellent, quiet concealed device!

fitted right this is excellent. I bought one several years ago and didn't fit it too well, this time I did much better and it works fine and silent in operation, with the aid of a little WD40.

I got the door closer to work eventually. Be very careful when positioning the door plate. The online advice is to fit everything then close the door to leaving a small mark on the door frame to ensure the correct position. This did not work. It ended up not being in line and the door not closing properly. A bit fiddly, wouldn't buy this type of closer again.

Wow, these are sooooo difficult to fit. I mean, rocket science level of difficulty. Don't make sure you get the correct tools or you're onto a loser straight away. Also. The stupid little bit of metal that's intended to hold it in position whilst you fit the closer side is absolutely useless. No biggie though, I still have 8 working fingers and most of my fingernails. Also, one more thing, set aside the whole weekend to install it; despite telling the missus "we don't need a carpenter, any fool can fit those". I am that fool. I couldn't fit it and no matter what a chippy is gonna charge, it's gonna be worth every penny - even if you have to pay his mortgage for a few months. All joking aside, it not an armature job. But it works a treat and I'm very pleased with it.

There is one positive review on this item, with some clarifications on the instructions (which are in parts wrong). That review suggests that as long as fitted in a certain way, this product will still work as intended. It’s the top helpful review. That review persuaded me to ignore all the negative reviews. Unfortunately, the truth is that this item cannot be adjusted for a slow, soft close effect. It forces the door closed aggressively regardless of how much or little you “loosen” it. The loosening function only changes the point at which the spring stops pulling the chain into the barrel. It doesn’t change the pace. In my situation, the door would aggressively slam shut, even if for the last 10 degrees, the spring has stopped pulling. Possibly it’s just the category and none of these would perform a soft close. I don’t know. But this one certainly didn’t work and was scary when fitting. The screws are also (as so often) made of a poor quality metal so will not survive jumping screwdrivers.

I've fitted quite a few of these and despite the other reviews they can be very simple to fit but you absolutely need a self gripping wrench often called mole grips. If you try to do it without you'll struggle big time. Clamp the grips on the nib on the back of the plate that screws into the door jam and you can pull the spring loaded chain out fairly easily and I've never had too much of a problem sliding on the locking plate provided. If you try to do it without grips you'll seriously struggle so if you don't own any go down to Wilkos and buy some you won't regret it believe me.

Good

Lleva instalado bastante tiempo y funciona correctamente tiene mucha fuerza. Fácil instalación y ajuste. Mejor que otros sistemas, porque queda oculto.

Usato per chiudere una porta in alluminio con vetro camera di un negozio,per motivi tecnici non potevo usare un mab. Pensavo che non aveva la forza di chiudere,invece per adesso sta lavorando bene.

Works great. I have e never I staled one before. I was able to
