Door Stud Pro Series Door Installation Hardware Tool Kit for 1-3/8" and 1-3/4" Pre-Hung, Slab, and Front Doors - The Single Person, Hands-Free Door Install Kit - Discontinued

These are exactly what I needed to help set 30+ fire doors in a hotel that's updating their look. Even heavy doors can stand with ease and be very stable. Lining up the hinges is just a matter of raising or lowering and wheeling into position.

I have installed Commercial Doors for over 40 years. They are heavy and often need correction because the metal frames were not set correctly, as we all know. I learned techniques to save my back over the years and discovered a different manufacturer of these door installers last year. I fell in love with them but they were not very durable. This manufacture is phenomenal! Durable, very adjustable and have a solid feel rolling around. I highly recommend this one. Worth every penny!! Don’t put yourselves through not paying the price!

For everyone complaining about the price here’s the deal if this rig was made from iron or aluminum it just wouldn’t hold up it’d break and then you’d be dealing with a door crashing down on you. A pro-grade steel rig costs more like $200 to $400 instead of $100 but that’s because it’s built to actually last. It’s not just about paying more it’s about getting something that works when you need it. You can spend a little extra now or roll the dice with something cheaper and end up in the ER your call.

The pad on one side of both units appears to be removable, but the attachment device is different and inferior to their smaller model. The problem that presents is as you try to slide the unit onto a 2 1/4" door (which is tight) this pad slides out of place and becomes wedged between the door and unit, making it very difficult to move. This caused a rip in one of the attachment flanges, which exasperates the problem, and will likely only grow worse. This unit has been used twice so far, and it is difficult to slide onto 2 1/4" doors, but the doors were not finished so at least it did not mar that. Other than that it is a very beefy unit and works well with heavy doors.

Works great for machining the door to accept hinges, roll the door to where you want to work on it and lock the wheels, rout for the hinges then roll it to where the door will be installed. I haven’t used them to hang the doors yet but they will work fine for that as well.

I ordered the commercial grade for 400 bucks and boy was the build quality cheap. I work on commercial doors all day everyday. The cheap tabs that you insert the shims into broke on the very first door 😂. You really can't make it up how crappy this thing is. Go buy a 100 dollar one somewhere else it'll probably be nicer than this thing. I could see this being great for a cheap bedroom door but if you are doing doors that weight 200+ pound doors STAY AWAY .

We are an Access Control Provider for Security and part of our servicing is replacing failed electrical components.We needed the Door Stud to help remove 4' wide fire doors from their frames so we could replace the full length hinges that have failed. The doors weigh over 250 lbs and are very wide at 4'. These Door Studs were game changers from trying to move and orientate the doors with muscle and a door dolly. Once we put these under the doors, leveled them to the floor we were able to easily remove all the screws on the frame with out binding and simply roll the door away from the frame. We replaced the hinge while it was standing and moved the door back in to place with ease! I can say the with a normal 3' 0" door and typical hinges, this is now a one man job. We did 3 Fire doors with complete full length hinges changes and having to drill 50% of the holes new in wood and steel done in less than 3 hours with 2 men. This is a game changer if you are doing heavy doors!!! Great product!

Had 10 solid core doors to install and I was able to do it in 1 day alone with these. As a contractor these are a must. The price is steep for sure but an investment in your back
