Needs a simple modification to work perfectly!

I give a huge thanks to justChill as his review was extremely helpful. As packaged it was extremely easy to just pop right in place. But I could immediately  tell it would not work if you wanted to tilt the camera directly downwards without obstructing the downward view. With that minor modification to cut as he instructed it popped right in place and now is perfect. I also used two small wire ties just to be safe and ran them through the holes on each side of the guard and now it is securely in place. Thank you again. Giving it 4 stars because had to do that minor modification.

This was very simple to install.  It did not fit perfectly, as I had to make small adjustments to the plastic endcaps, but it got the job done!

I had to remove the ignitor from the metal holder (did not fit my oven bracket) and had to remove the plug and used the wire nuts and it works just fine.  If everything had fit just right without these modifications I would have given it 5 stars.  Anyway, it's a bargain - they want a lot more money for the same part at local suppliers as well as other websites.

Didn't fit Like it was suppose to. Had to modify it to get it to work.

yep, this is the fix. I had to snip one of the ends to get it to fit
but this is what you want.

I'm definitely willing to change my review to a 5 star if I could just get the upper pole to thread. It doesn't tighten properly, likely because the top pole is the wrong size. Am I missing a part that makes the two poles fit snug? I just want this mic my bass drum, and so far it doesn't work straight out of the box. :( Can someone tell me if I'm doing something wrong, or are the reviews saying it works forged? I'll return it soon if I can't get it to work. There aren't any instructions for me to see if I'm setting it up improperly, understandably so. It's a very simple design, which normally is great. Simple works. The problem is that when simple doesn't work, the whole design doesn't work. I really want to change my review and have this work, seeing as how the functionality I'm looking for is incredibly meager. Someone please help.

Electric quick connect did not match existing splice, had to make pigtail to match up, I should not have had to do all that. I had to "make it work".

Junk instructions, poor design, had to make it fit

After reading other reviews of this little shelf unit I must assume that the manufacturer changed the specifications. To start with, my husband snapped the end off of one of the upright connectors. I figured it was just his brute strength, so I said "let me take over". Well, I found that there was absolutely no way that the ends would ever fit where they needed to go. I sat and trimmed them with an exacto knife and then filed them smooth. The little thing is all put together, a bit of glue helped out. I like it fine, but the manufacturer should make some changes.

The most complicated and irritating part of installing this roundbar WDH is getting the angle correct on the adjustable ball mount.  It's trial and error to get it where it needs to be.  And the trial and error involves removing all the hardware, resetting the knob, then going back and installing all the hardware again.  I got lucky and nailed it on the 2nd shot.  My truck sits well and handling is night and day from not using a WDH on our 24 ft travel trailer.

To do this right you'll need a hitch ball wrench similar to:

I would also recommend either a jumbo socket set (up to 1 1/2") or a large adjustable wrench):

These are tools that you WILL need in the future when making adjustments as your towing needs change, so they're a good investment.

I really like it but it only gets 3 stars because it needs modification to make it work. The tab is too long by a couple of 100ths of an inch and I filed it off a bit before it would work.

I got this thinking that it would work with my PR1000. To my surprise it didn't fit. So I had to get creative. You have to install the Rods as in the slots available. Then you have to turn the assembly so that the grooved area faces the metal column. This is the opposite direction of how it supposed to be installed. You will have to put in a wedge of 2/3 - 3/4 to fill the gap between the plastic box and the metal groove that holds it in place. Then just screw in the other side and you are done.

Only the people that have it will understand. :(

It looks well crafted, but it could not solve the problem I had.

My problem was the cartridge was broken in half and the white housing component was stuck in the pipe. For that, try a 5/8 inch, sharp drill bit - twist it so that it bites into the plastic and use it as a puller. If the black part is in there it's 13/32 one and I saw a video of it on YouTube also.
