3 Pack 4.5" Heavy Duty Commercial Door Hinges 4 ½"x 4 ½" Satin Nickel Ball Bearing Door Hinge 4-1/2 x 4-1/2 Full Mortise 4.5 Inch Square Interior/Exterior Hinge for Doors Bifold Residential Office

I needed to hang a recycled commercial solid core door (1-3/4 inches thick) and these hinges were perfect. The door weighs about 110 pounds and with three hinges it moves with a finger-touch, the bearings in the hinges are fantastic -- completely silent as well. The hinge sets come with a compete set of wood and also sheet metal screws so you can use them on any combination of steel and wood door and jamb setups. They are much thicker than regular light duty pin type hinges and even with that heavy door on them, there is no deflection at all as the door moves.

I bought an open box that was much cheaper. Excellent quality with bearings.

Super heavy duty hinges for my solid exterior doors, at a fraction of the cost at our local hardware store. One of the boxes only had two packs of screws. (Supposed to be three packs) Other than that brief setback, I was very happy with the cost and quality of these hinges.

Door Hinges Hardware Hinges 4.5 Inch Square Interior Hinges for Doors Ball Bearing Door Hinge 4-1/2 x 4-1/2 Full Mortise 3 Pack Silver Exterior Door Hinges Bifold Residential Office Hinges 4 ½"x 4 ½" This set of hinges is really heavy duty. Larger than standard American residential door hinges and with ball bearings. They are probably medium duty commercial door hinges. I have some heavy glass interior entrance doors in my commercial building that are hung in aluminum frames. I believe that these hinges are a direct replacement and I ordered them for spares.

These commercial hinges are strong, made of high-quality material and made to last. I use them on an exterior commercial door that needed to have durable hinges in place. They were easy to install fit perfectly on my exterior door and they look great. Definitely a great value for the money.

Love these, very heavy duty and thick. Good travel and movement. Very good hinges I am very happy with them, they seem like they are high quality.

I have a very heavy locker door that I used these hinges on. There will be about 200 pounds hanging on these hinges, and I think they will hold up just fine. The finish is pretty good, and all the hardware is included. There are 2 sets of screws -- wood screws and metal machine screws too. They seem very well made and open/close smoothly. Getting these hinges mortised into the edge of the locker doors was not too hard. They are nice an thick -- about 1/8" of an inch. 5 stars!
