Question: Is the tension on these hinges adjustable, my doors are smaller and lighter for a restaurant service area and will get alot of use.
Document: I am going get another large hinge for the bottom of the door because I think doors should have 3 hinges.
Garbage beyond comprehension.Was replacing old small hinges after years of service, bought these because they are 6&#34; and heavy duty.I did not even get them adjusted before they sprung during testing.This item should be removed from amazon.I waisted my time and labor installing, then removing and reinstalling old hinges.I received them on time. No contact with Merchant.Packaging was fine.
INSUFFICIENT CAPACITY PRODUCT:The hinges are not able to lift a 1-3/4&#34; door and tension ring broke when tightening it. The hinges are no use to me unless you send me a replacement hinge for the broken one and two more hinges to be mounted at the top end of the door to lift it. It definitely takes three hinges with two at the to to lift a 1-3/4&#34; door. Regards, Fred Kaune
These are quite heavy duty, but still would not support the doors I was attempting to repair. I used three hinges and the weight of the door still pulled the top hinge open a little, enough so that it wouldn't operate.
Had purchased other hinges at a national chain store and they just didn't carry the weight of the door. I called customer service at this store before purchasing with questions as to capability of the hinges and was assured they would work. The person I talked to was great, answering all my questions in a friendly manner. Received my hinges in the time frame I was told, installed them and they worked great. Will purchase from this store again.
It was a little difficult to put the maximum amount of tension on the springs but a vary good product.
Bought these for our restaurant, the swinging door into the main kitchen. I went through 2 other sets before these. I confidently say these are going to outlast the building!
Strong and have withstood a heavy wooden restaurant kitchen door for several months now. There is a slight creak noise but I'm sure a little grease would fix that up. Haven't done it myself since the music and kitchen noise level overpower it.
We bought similar hinges from HD and they broken once we put them on the door. We bought these hinges and the door works perfectly! They are heavy duty hinges and a look a little big for the door, but work great. They were easy to install too!
I took too long for delivery.After installation of 3 hinges each door ,it make very annoying squeaky noise.even applying Silicone Lub doesn't help.I already pay a lot of money to install.
Answer: yes
