Double Locking Bi-Fold Door Hinge
I haven't used them yet but they are exactly what I hoped they would be. This is to make a folding gate so my granddaughter won't fall down the stairs. They are very well made.

Have these on a bi-fold dog gate and one of them broke after two years of constant use. The hinges lock the gate open or closed into its cabinet recess.

Hopeful cure for bifold closet doors that will not stay flat when closed, even when properly aligned.

They work very well and we prefer them over soss hinges.
Jeth O on Sep 1, 2015
These hinges were used for the doors I put on my wife's sewing cabinet. They really keep the doors on place, weather open or closed. They are really good hinges, very sturdy.

Need to secure bifold doors on bifold TV cabinet doors.
J A on Apr 23, 2015
These hinges do cause the door to "spring" into position. Moreover, they stabilize the apposition of doors better than flat, spindled, bifold hinges do alone, as they are heavier and without bushings.
Jim C on Apr 22, 2015
Loved this hinge very strong and much nicer than a piano hinge

I have a bi-fold exterior tv cabinet with double doors. I have a problem keeping them open, especially when it is windy. Will these lock the door completely open?
choppy21 on Jan 14, 2016
BEST ANSWER: The application for these is for between the outer and inner doors,so the inner is held against the outer. The tension is adjustable, so if you can apply them as the outer door hinge I'm sure they will work for you.
how much weight can this hinge support?
A shopper on Jun 15, 2015
BEST ANSWER: Without actually weighing the doors, I would say any weight is within reason using the proper amount of hinges. If your doors are taller and heavier it will hold, but you would want 3 or 4 hinges per split instead of trying to make due with 2 (There is no deflection on smaller doors). There is no room for error when setting these (no adjustments), but if take the time to line up everything it will go fine. My customer specified these and I was forced to use them and have since used them a few more times. They do exactly what they are supposed to and are not very complicated. I hope this helps.
A shopper on Apr 9, 2015
BEST ANSWER: I recently purchased the hinges and it came with what I would call a dark gray metallic finish. I was looking for a nickel finish and will probably look for some spray paint in a can to repaint it to a nickel finish
Would these hinges work on a door stile width that is only 3/4"? I am having a hard time finding good hinges for my closet bifold doors, which were just refinished to have a sleek, modern look.
Rachel S on Jan 11, 2016
BEST ANSWER: No, they will not work. You need at least 2"on each door style. You can get away with 1-1/2"
What is their weight rating? Can they be used horizontal (flat)?
Travis on Sep 2, 2019
BEST ANSWER: I can't answer the weight rating, but I am using 3 hinges to hold up an aluminum fireplace heat shield that is 4 feet long and weighs about five pounds. They are mounted to the inside top of my fireplace in a horizontal position, get very hot when fire is lit, and have been working great for over two years.
will they work in closet folding doors?
Jose L. F on Dec 19, 2017
BEST ANSWER: Yes, so long as the door stiles are wide enough to accommodate the mounting screw placement pattern. The hinge leafs are about 1 1/8" wide but I would want additional width to avoid the risk of splitting the stile.
I have two, double 80 " lightweight French door that will not stay closed despite adjustments. They just keep buckling open. Would I need 2 or 4 of these hinges?
Messenger S on Nov 7, 2015
BEST ANSWER: on an 80" door I would use 4 hinges. 1 - 12" in from the ends and then evenly space the other 2. Make sure the adjustment knob is facing the same way on all four, and that they are all properly centered on the doors as you install them. I always use a square when I install them to make certain that the mechanism remains parallel with the edge of the doors. These are a great hinge that I have been able to find no where else.
What is the center to center exterior hole location of the holes on one side vertical? What is the center to center hole location on horizontal across both sections?
Kaye C on Apr 21, 2020
BEST ANSWER: Holes closest to the outside of the hinge leaf are 1.25" apart, vertically. Hole spacing horizontally across leaves are 1" and 1.75". I drew a picture with all dimensions for you, but I now see that one can not share links or images in the answer. I hope I explained what you were asking for.
Could these be used as hinges for folding table legs?
Cal C on May 5, 2019
BEST ANSWER: I don't think so, they go from flat to fold in half, you would want something that would stop at 90 degrees, these might work for a table to fold in half, for reference purposes
I just bought these but it appears that they don’t lock in the fully closed position? Mine will fold fully but then it bounces back to lock in a position that is mostly folded but still open a bit. Is this how they are designed or is mine defective?
Robert G on Jan 10, 2019
BEST ANSWER: I think I know what you're experiencing. Mine do fully fold and stay folded. There seems to be a half-way folded position - with the doors about 6-8 inches apart - that's part way between fully folded and fully open. Mine tend to pause there when opening them all the way. But yes, mine do stay fully folded. Good luck.
I'm looking for something that will lock at 90 degrees and 180 degrees - will this product do that? Also, what is the weight bearing capacity of these hinges? If I use two hinges to hold about 75 lbs. will it remain in a locked position?
25questions on Dec 14, 2016
BEST ANSWER: These hinges do lock at 90 degrees and 180 degrees. I'm not sure about the weight capacity but we have them on 6 foot solid oak bi-fold doors that are very heavy and they do a great job. We did use three hinges instead of two because of the weight.
I just build 4 folding doors for 2 section using these hinges. Doors are 24×82 for 4 hinges on each door. Somehow it doesn't stay flat.
Do you know why, and is this hinges can be adjust the tension? Than tell me how to adjust tensions.
I push 2 door to be flat than other 2 are open. Can you help?
Christina on Nov 22, 2017
BEST ANSWER: I am assuming that the doors are no thicker then 3/4" because the sizes you stated are very large and weight will affect the hinge performance. Also are all the hinges facing the same direction? Check to see that the "knuckles" go the same way ( I don't believe it matters which way just that they all go the same way). The hinges you use on the "swing" end also matter and plan on using a magnet or catch to secure. We use these often and if you have tried all these suggestions, add at least 2 more hinges and leave a 1/16" between doors to prevent binding, good luck!
What is the difference between this and the Folding Door Hinge
Item #: 30041? Which one would be better to convert n small wardrobe door to a bi fold? Without the use of a runner.
Monica N on Jul 21, 2017
BEST ANSWER: I am unsure what other hinge you are asking about but we use this hinge for appliance garages and large bifold pantry doors ( cabinet) these are best because they lock in place both closed and while open preventing swing back or bounce open, this is only for the center joining of doors not the actual swing from the side panel, I hope this helps some.
Can these hinges be used outdoors for a gate?
bifoldGate on Dec 11, 2016
BEST ANSWER: The hinge is not rated for outdoor use. Also, I don't think they will support the weight of an outdoor gate.
