Nuk3y Door Saver 3 III Hinge Pin Stop for Residential Doors Fits All 3"" to 4-1/2"" Hinges (Satin Nickel)

Installation was easy and I love them. No more dings on my door. I just wish I have purchased them sooner.

This actually works well. And it prevents having doorstops stuck into the wood or on the wall. It is a little more difficult to install, but it’s worth it.

Cool idea but I don't like the reality of how this works. Another reviewer mentioned that the door will continue to swing open after this product has engaged at the hinge pins. I didn't quite understand that until I installed a set of these on a hollow interior door. Firstly, when this product engages at the hinge pins, it "binds" against itself and that is how it essentially attempts to stop the door from rotating. Problem with the binding is that depending on the velocity of the door rotation, the product will actually elevate vertically above the door hinges. Don't like that from a functionality perspective. Sure, it's binding and stopping the rotation but it is flexing and doesn't actually stop the rotation on a point. So the previous reviewer wasn't lying when they said it will continue to swing open. Secondly, this product has many splines on the inside which is used to set the point of stopping. Seems nice for the adjustability but from a geometric stand point, spline represents a specific degree of arc of the door. With the product set up and you go to test how far away from the wall it is when the product is engaged, it may appear you have, say, 6 inches of space. You realign the product to utilize the next spline in an effort to get the door closer to the wall when opened. Then you realize, the product never engages because the door now hits the wall. A small adjustment at the most inward point of the angle equals a long adjustment at the further point of the angle. Hello, remember me? It's me Geometry here to smack you in your middle-aged adult face. Lastly, from a design point, this product binds at the hinges - it attempts to stop door rotation from the most inward point of the door/hinge angle. Think of it like using a car jack, if you have a short handle - you feel a lot of effort, whereas if you have a crazy long handle of something - you feel way less effort but you have to move more distance to jack the car up. What I am getting at is if the door has a stopper at the edge of it, the amount of force required to stop the door isn't too bad, whereas by stopping the door at the hinges requires way more force (read: binding of product) and transfers all that energy to the actual hinge screws in the door and doorframe. And that's Physics now smacking you in the face. So cool idea as an alternative to a doorstop on the wall/door but I will not use it. BTW Amazon sent me a returned item that was all greased up and had dirty fingerprints on it.

These work well for doors that can’t use a regular door stop. I have several doors that open to closets or other obstacles and these are great. When the stopper catches I hear a light crackle sound that makes me nervous is someone slammed the door open it might splinter the hinge though. I haven’t had any issue though. I had the other kind of hinge stopped on other doors and they made holes in the molding around the door so I’m hoping these will be better. Minute one star because the instructions weren’t very helpful, but otherwise I think they will work. They are a lot smaller than I thought from the picture which is good. I thought they were going to be bigger and bulkier. A little pricey but if they work it’s worth it.

Very easy to install, works perfectly, totally recommend.

Great invention! To me this is much better than other door stops! Slips on the hinge pin and done. Prevents door from hitting against the wall. Great investment! You basically do not notice it.

There is not enough adjustability with these hinge pin stops. I have placed one on a bedroom and one on a bathroom door. Both doors need to open to almost 90° before hitting the wall. For some reason one of them on the bathroom will open to almost the perfect stopping spot but the one in the bedroom either hits the wall or stops way too far away from the wall. Just can't seem to get it right. I don't think the "teeth" are fine enough to enable small adjustments.

They work great! As described

j avais besoin de quelque chose de très discret et fait bien le travail

I had high hopes for these, but they are too big for internal door hinges 0.6mn dia external with 0.4mm dia pin. It is more like something that works for our front door hinge if it was a pin hinge. Maybe not great for UK hinges unless they could scale it down? Also one was missing the clear plastic top washer.

Not a great product because it bites into the door frame. Would work fine possibly on a steel frame door

didn't work

Didn't work in our door
