Said to drill holes 16" on center into wall so we did. Holes in railing were less than 16 so had to redrill.

Instructions consist of pictures and is in metric. It has predrilled holes in the bar that are 18 inches apart not standard 16 inches. We had to put a header up just so the lag bolts would hit solid wood and hold the door up. The hardware is very nice but with the other issues I will not buy it again.
Update: the store contacted me and state they are changing their holes to 16. I appreciate they took what I wrote in consideration.

Nice piece for extending my 2" receiver by 8 inches. Unfortunately Curt seems incapable of drilling the holes in the center. If you buy these you might need a big round file to get a pin through it.

Look this cabinet is great, I had no problem putting it together, and my doors work fine! The only problem I had was the drill guide for the screws to hang it up was wrong. Just check that before you put holes in your wall.

Hard to install in a 1 1/2 inch thick counter.  I had to use liquid nails.  Additionally the "center hole" marked underneath the sink for drilling to install a water faucet was off center!  Grrrrrr!  Lastly using only 1/2 inch for modifying the outline of the sink for cut out was not sufficient.  If I had to do over again I would use one inch.  Other than that my wife loves the sink and it is functioning as we had hoped.  Only time will tell about the sink maintenance.

Nice size for my basic serging thread cones.  Unfortunately, as another reviewed indicated, you have to drill through the wood if you want to mount it on the wall.

I got a nice email almost as soon as I bought it explaining what was needed to attach this to the wall (a drill!). So this is not for the average five thumbs person to do. I had a handiman put it up; now we'll see whether the "balls" that hold everything in work without breaking. Cross your thumbs.

I never installed b/c it requires you to drill through the ENTIRE door (from one side to the other). I have solid doors and do not want to mess them up with that type of hole.

I bought these from Lowe's to put on my window curtains. There was already two holes on each side before I even started so I thought awesome! Behind the paint there's mudd then the cornerbead. House built in 69.  I thought all I would need to do is screw in the anchor then screw in the nail and I'd be done. WRONG! The first anchor I tried to hand screw with a #2 Phillips as directed, only trashed my drywall going around the stud/cornerbead. Completely trashed. The box says NO DRILL REQUIRED. Yeah that's a load of crap because I had to drill into the wall with my 1/4" bit so the anchor would even think about catching the cornerbead to sink in. So it still didn't catch. I had to ream it out a little more. After doing all that, it finally went in. But now I have a trashed corner that's somewhat covered. An ill have to fix that later.
Note to buyer:
If you have a stud or anything other then dry wall. You'll need a 7/32" bit and a 1/4" bit to ream the hole then some elbow grease to shove the anchor into the wall.

drilling holes in 3/8" marble and granite tile to install shower walls with a constant stream of water - I was getting just about 3-4 holes per bit.  ended up buying a second set because I had more holes to drill.... then ended up buying a more heavy duty bit at Home Depot to finish the job.

It does the trick for a few holes, but don't expect too much life out of these.  But the price is right.

This product requires your wall studs to be spaced 16" apart.  I found it incredible that you have to actually find this in the manual.  24" stud spacing is fairly common I think, and a wall mount should be compatible with both.  Or at least put that into the product description!!

The return shipping for this 48-pound item is NOT cheap.

Had to modify for my application.  Hole way too small.

Had to add two screws to anchor to wall (and drill corresponding holes in wood panels) as the ones provided are not enough to keep it up with heavy objects.

Beware the fittings are 1/2 inch and if you have 3/16 in the wall your gonna have to rig it up.

Looks awesome, instructions were easy to follow. Might want to check the distance between the studs in your house before you order though. The instructions assume you have 16" studs and my apartment has 24", so I was only able to mount it to 2, rather than the recommended 3 studs. Hopefully it doesn't fall off the wall.

The holes are off-center so be sure you get them mounted so the holes are closest to the doorstop. In case you don't know, there is a small space between the door jam and the actual 2X4 behind it. The only problem i had was finding a drill bit long enough to reach the 2X4. Of course, I wanted them level. So I measured and re- measured and then put a 3 foot level across the marks on the frame. But that's just me. very sturdy once you get them in right. And it's not that difficult to do.

After getting the mount part onto the wall, we discovered the screws that hold the adapters onto the TV do not fit into the TV 's pre drilled holes!! Now we have unnecessary holes in the wall, unless we venture out (defeats purpose of online shopping) to home Depot to find screws that do fit!!!Grrr! Searched.for this item by specific make/model of our TV and this was the first match. Disappointed.  Made a simple task difficult.
