How does it work on metal doors?

The hole saws are bi-metal and welded construction (not 'pot' metal), and these saws should work fine on the thin skin of a metal door. A few drops of oil and a slow speed can keep the saw in good shape. The plastic fixture should work fine -- just keep the drill alignment true to keep from cutting the fixture. However (per my amazon review), my arbor and hole saw failed on the first try because of several significant design issues. 1. My arbor was not threaded all the way to the backing plate -- this allowed the large hole saw to 'cut' its own threads on the arbor. Since the threaded base of the large saw is only several threads thick, it didn't take long before the assembly stripped. 2. Also, the large saw (2-1/8" diameter) can create lots of torque on the 'small' threaded arbor/saw interface. Note that high quality hole saws with a diameter greater than 1-1/4" typically are mated with a quick change arbor with locking pins that keep the destructive torque away from the 'weak' threaded interface. If you already bought this product and your arbor is not threaded down to the backing plate, I would suggest the following. Add several 'spacer' washers between the saws and arbor -- this will keep the small hole saw from getting 'stuck' on the arbor, and the large hole saw from stripping the threaded interface. Run the drill at a slower speed and don't push hard. The metal skin should drill easily, however, I think drilling through the wood under the metal will produce much more torque. Just be easy on the drill and it should survive.

The jig is just fine. The bits are crap! Pot metal and strip out with little torque applied. Get good bits and it'll be just fine.

If the metal is not too heavy or too smooth it will attatch momentarily. However, the metal thing will come off later on.

It works on a hollow core door (where we put it); however, I bet it would work on an aluminium door. You may have to put caulking around it to make it more secure. I believe someone said it did in the customer reviews also.

I have mine on a steel exterior door. I did use two (of the three hinges) to provide more closing force. Works great!

I used it on a metal door but if you use industrial 2 way tape and know for sure that it will stay and not fall and break than Glass might work also. good luck.

Sure will , they are simple magnetic contacts, a metal door or window wont effect them at all.

We have ours on a metal door. Our house was broken into and we used these for the replacement. 2 weeks later, another burglary was attempted however they were unsuccessful with the entry because of this set! Highly recommend them. Love it!!

I have used this on many things and it works very well. I have not used it on Metal.

My husband and I just installed our door. Its great. There is like a 2" metal floor guide that sits just outside the opening that has two small rollers keeping the door bottom straight. Since this was our bathroom door and was being put on tile we skipped the step of screwing it in the 3 holes and attached it with a clear epoxy. Works great.

It has something between the metal and the door but I can't tell what it is. Because the metal over the door didn't fit tightly and wobbled I used 2 screws to secure it to the door. It is working wonderful for me.

It will respond to the amount of tension you input. The less you tighten the hinge, the less force to close the door. However, to use this product, there are several different factors to consider, besides the product. Such as type of door, type of door jamb, and door jamb trim. My opinion is that because of stress on all of these areas, a metal door and jamb is going to work better over time than a wooden door and jamb, but is applicable to both uses.

You may have problems installing in a metal door. When I did my first installation I used hvac metal tape and the SureFlap didn't work. When I called support they indicated that metal adversely affects the operation of the SureFlap door.

Have not tried it on anything but metal -- does wonders on stainless steel sinks!!

I have installed this on my entrance door which is Metal and did worked well, as ling as the thickness of the door match and the distance between lock hole the edge of the door is right, this will work fine.

I used mine on an interior hollow core door, so don't know. However, it has decent holding power. Depends on your closer. I recommend you buy one (seeing as they are relatively cheap), screw each half to separate blocks of wood. Clamp one to the door and hold/affix the other near your hold-open position to test it. Or just get a latching stop like most other closer assisted metal doors I've seen. But then you'd have to bend down every time you want to latch or unlatch. I'd say the test may be worthwhile.

Sort of. I used it to cut out the slot for the door knob's latch plate, opposite of hinge. It wasnt very successful on the cardboard-like material that it was made of. No clean edges and difficult to control. I had to clean it up with a chisel. It may work better on a real wood door, but since you dont want to mess that up, you should just do it right.

Assuming your commercial metal door has a door lock on the door and a striker plate on the post, the electric door strike will work if there is signal to release the strike.
