Hudson Hi Fi 1U 500 Series Universal Blank Panel, Rack Mount Spacer for 19 inch, Breaker Filler Plate made from Steel, Black Matte Finish, 1 Pack

Is it possible to make a cover plate without enough clearance so that it won't fit the most popular box around. You wouldn't thinks so but these guys did. Couple that with inconsistent machining in the screw hole diameters (a couple screws had to be forced through the holes). I'll have to take a file to the sides of a couple of these so they'll fit. If there are other options go there, or just be resigned to having to shave some down. Too bad because they do have a nice finish.

They feel of good quality, and look great; but, their hole spacing is too far apart as they are too long.So I initially thought I'd drill the whole(s) bigger, but that will not help as these are too long by 1mm and some change. Not a big deal if you have only one lunchbox chassis, but it is if you have multiple in the rack. So I'm returning mine.

Last year I bought a set of 4 blank panels and they fitted well in my lunchbox (good dimensions, no gap). I needed more as I built a 11 space lunchbox and currently have only one module, so I ordered another set (8 blank panels this time). And now they don't fit!I suspect that the build has changed because for the first set I bought the panels were sturdier and heavier. The new panels I received are way much lighter, and they didn't take much care in mechanical tolerances... So I can only fill 8 of the 11 slots of my lunchbox... I guess it will be better than nothing against dust!I never understood why these blank panels were so expensive when you buy them from famous manufacturers (Midas, Fredenstein...). It seems it is more difficult than I thought to build a rectangular steel plate with two holes inside... I will try grinding them with a file to see if the problem comes from the paintjob

These are really high quality and look great. Came well packaged. However, the smallest concern... they are slightly smaller than the rack modules themselves. In my lunchbox the actual units have no space between them, but everywhere I use a blank panel: next to another or in between modules, there is space between them... noticeably. For something designed to keep dust and dirt out, that doesn't seem to make the best of sense. From a just good looks perspective, they are great. I am still happy with the purchase, but wondering why all my modules fit fine and snug... and these are all just a tad too narrow? Oh well... I guess that's why not 5 stars...

I bought 2 panels for my Rupert Neve R6. Although other reviews have concerns over the panels leaving gaps, I will probably be filling in the remaining 2 slots before the end of the year so the panels are just temporary and these are a much better price for a short-term solution than the Neve panels. As it turned out, they're a really good fit. There are small gaps, but quite small, and I don't envision having problems since I keep a clean room. As a bonus, they included screws which I didn't need since the R6 came with all it would need, but it was very nice that they were included.

500 series blanks are hard to find at a good price and these do the job. But, fit and finish is quite poor. The blanks are all slightly off from each other dimensionally and some of the screw holes are wonky. It looks like they are extruded or stamped using a really old die that is badly in need of a refresh.Also, one edge has a standard 90 degree edge while the opposite side is beveled. Makes you scratch your head a little bit...

These are about 1/64 inch wider than the 500 series modules I have so trying to fit 8 of these over blank spots is nearly impossible. (8 x 1/64 = 1/8 inch). I plan to fill the slots so I'll just grind these down and keep them until the slots are full. But beware, they're inexpensive for a reason. I am using a Midas L10 chassis.

The thread holes are small for the screw and the panels are uneven. For most of the panels I have, the thread holes aren't placed properly so I can only really screw in one side.Giving this a 2 because it's kind of my fault tbh. I always wondered why blanks were $20/each and I figured it was just the usual audio gear price gouging. Nah, this product really reminded me to read reviews and spend the extra dollar

I have the radial workhorse cube box, they fit nice and lined up of course, some review's said they would not fit on some people's lunch boxes. but this was fine for mine.

Quality is great, finish is fantastic, but they are a little too wide rendering them useless. You have you stack them over each other a little bit which is a huge eyesore and not the point of getting covers

These were great and fit perfectly in two separate 500 series chassis’s I have.

Fit well, thanks for extra screw. I dont like the paint and the finish.

Not only are these a great price - they are actually the best fitting blanks I've used. A+++ I'll be buying these again. Shipped fast as well.
