NationalHardware N185-199 V521 3-1/2 Inch Commercial Brass Adjustable Full Mortise Spring Hinge

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!

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.

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.

Product was a complete waste of money. Unable to open the wings to install. Firmly clammed shut. Followed instructions to release tension but unable to loosen. Passed to MOTH but no success there either.Ditto second pack.Very flawed design.Why isn't the hinge dispatched from the factory in an un - tensioned state so one can install it?

Installed on the door between kitchen and garage. Installation was simple, the hinge mounting holes lined up exactly with the previous 49 year old hinge. It came complete with all mounting hardware and detailed instructions for adjusting the closing tension. The only slight negative was that the packaging had been opened but it was complete so no issues. Yes, I would recommend this product!

Works like a charm. It was pretty easy to install and adjust. I live in a household with many pets, one of whom wants to claim his territory by marking everything in his perceived little kingdom. Since I can't reasonably take him for a very, very, very long drive, this was the next best solution. I would occasionally forget to close my door, and ninja kitty took advantage of every possible opportunity to sneak in and stink the joint up. You've seen it before, they back up to something trying to look nonchalant, a rear leg or tail twitch and BAM!!, you've been hit. But I digress.This hinge worked great, in that I can no longer leave my door open. If you need a way to keep subversive little monsters out, treat yourself to a spring loaded door hinge or two. For the record, I have a fairly light interior door and only needed one. My use of floral smelling air fresheners has been dramatically reduced.

If you quickly look at the listing it says 2 pieces. But when you get it there is only 1 in a pack.

Another example replacing plain hinges with something to pull the inside door out of the way when others forget. Out of two doors, four hinges, one pocket needed a little trimming to get new hinge to sit flush. I used a couple "clicks" from the as-delivered position to get a gentle pull on the light interiors doors, not enough to engage the latch. Adjustment included trying a couple more clicks (which gave full close but noticeable resistance on opening) and backing off (remember to depress to clear the internal catch). Overall, pleased with install.

I've tried two other styles of door closers. One was the kind with a rod that you screw into the door, the other was a hinge pin. They're both trash. I used them for my bedroom door, and had to crank them as tight as they could go and it still didn't close the door. Not only that, but they're a real pain to install. The rod style broke within a day, and the hinge pin pops out constantly, forcing me to re-torque it with the included tool. Needless to say, they're both incredibly finicky and unreliable.These hinges, however, work like a charm. The instructions say not to crank it more than 6 turns. Three cranks and the door closes like a charm. I bought two for each door.The price is WELL worth the product. I'm thoroughly impressed!

These work well and were fairly easy to install once we figured out what we were doing.

Purchased so when the cat barges into my bedroom, the door swings back to almost a close. Had no troubles installing but when setting the torque, I went one click too far for my cat to be able to open the bedroom door herself from inside. @ 4 clicks of torque, finding it absolutely impossible to decrease torque as per the instructions included (push down then counter clockwise).. not sure if exceeding 6 clicks will reset the torque?.. since I dont know that I guess I wont be removing it to attempt decreasing because if I can't exceed 6 and reset it, or if it's faulty and can't even decrease the proper way when removed, I'll probably never get it back on at that torque.

Was able to install ,however while installing spring tension bathers and there must be a quick way to remove tension from spring, which will make it easy to install. Worked with minimum tension on my solid core 32 in ch door

Developed a squeak quickly and was a bit difficult to install.Be careful, or it's basically a mouse trap attached to a door when installing.Wasn't a direct swap for the old hinges.
