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!

Good

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

Solo que es un poco engorroso de instalar, pero vale la pena.
