### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect, very high quality hinge!
  

*by Y***G on Reviewed in the United States on September 5, 2014*

Exactly what I was looking for.  This is a high-quality hinge, far nicer than I had expected.  I'm not certain, but it looks like it's been milled, instead of stamp-cut like the cheap contractor-grade hinges.  It has a nice heft to it, with very clean edges and milled countersunk holes. Compared to the (cheap) brass hinge I was replacing, this is just a tad thicker--shouldn't be enough to affect replacement of one existing hinge without replacing all of the ones you have, but if your door is hung with very tight clearance, this *might* prevent the door from closing easily.I wanted an interior hollow core door to close on its own, because my family members were constantly leaving the door open to my home office room, which is air conditioned and filtered for controlling dust.  Though I bought two, you only need one of these for an interior hollow core door--there's plenty of tension that can be adjusted, and I think even two might be too much.  I replaced the middle hinge of the door with this hinge, so that the extra thickness I mentioned above wouldn't cause the door to hang out of level.  Tensioning/detensioning is easy, and directions were fine.  I'll definitely buy these again!

    Works well!
  

*by M***L on Reviewed in the United States on February 18, 2024*

I only installed one of these onto my bedroom doors to allow the doors to swing shut when the cats enter the bedrooms. One was more than sufficient for the lightweight hollow core doors.  It has a few settings that you can adjust for how hard the door closes. I set it to the lightest, to allow the cats to be able to push/pull the doors open.  It wont close the door all the way at this setting, which is perfect for what I wanted, but you can adjust it higher to fully close the door.My only gripe with them is on the strongest setting, its really difficult to adjust the screw to loosen it up again. The way it works is that you can torque it a few times to increase the door closing strength, or push in the adjustment screw to unlock it and reset it to its lowest setting. Thankfully you pretty much just need to set it once and then never mess with it again. Also, I much prefer this method to some of the other hinge designs that require you to insert a locking pin, which just seems very flimsy to me.Overall the hinges feel like theyre very good quality. It came with a lot of hardware for installation. Value isn't what I would like, as many of the other self closing hinges are much cheaper.

*by V***S on Reviewed in the United States on July 11, 2022*

I bought two of these hinges for the twin doors leading to my pantry.  For years I've been unhappy with the doors because I would always have to push them closed to ensure they engaged the magnets and stay closed.  I installed one hinge in the middle of each door after reading the instructions carefully.  Following the instructions, I disengaged the internal mechanism, installed the hinges, and then tightened the mechanism 4 or five clicks until I got the result I needed.  Now the doors close firmly enough to engage the magnetic catches, but gently enough to not slam shut with a bang and the risk of their bouncing off the magnetic catches.  Very satisfied with these hinges.  Wish I'd found them years ago.
