Questions and Answers
Q: What screws are these hinges packaged with?
A: Typically (as a rule) these hinges are shipped with, all metal screws and half wood screws (meaning you would get enough screws if the door and frame were metal and enough wood screws if either the door or the frame was wood).

Please let us know if there is anything else we can help with.

Q: Question: What is the weight limit for a standard weight hinge for a residential fire door the uses 3 hinges?
A: Please tell me what is the size of the door, please tell me the frequency of use and please tell me the size of the hinge.
Q: The door is 36" x 80", 1 3/4" inch thick, metal with wood interior. It would be used very often. Probably 8 times per day. Justin K.
A: The short answer to your question would be a hundred and fifty pounds.
Q: Sorry. I forgot to put the current hinge measurement. It's 4.5 x 5, but newer hinges seem to just have more compact barrels. I think 4.5 x 4.5 is what I need. Please see the attached photo to view the old hinge as seen here:

This will bring your door to an acceptable of code compliance. The hinge itself has a life of building warranty.
