I-Semble Heavy-Duty Blind Shelf Supports

Gain practical storage space while maintaining a clean, modern look. Once installed, these concealed shelf supports are completely hidden from view, creating the illusion of a floating shelf. They are made of sturdy metal with thick posts, and are securely screwed to wall studs for a weight capacity of up to 125 pounds per pair of supports. Shelves should be a minimum of 18'' long in order to span two studs. One pair of brackets can support a shelf up to 48'' long. If you need a longer shelf, just add additional brackets.


  • Height adjustment slots let you level the shelf if your initial holes are slightly off
  • Tilt adjustment screws ensure that the shelf projects from the wall at 90°
  • All hardware is provided, including mounting screws—you provide the wall space and the shelf

Great solution.
You have to pay attention when measuring and installing but the results are wonderful. I installed on a wall consisting of concrete block, wood strips and drywall, very strong.

these worked prefect for my project, just need to be able to drill a nice straight hole and your in good shape, and make a grove in the back of the shelf to allow shelf to sit flush to wall..

Hidden shelf support
These are the best on the market. They help adjust the leveling of a shelf as you want. It is difficult to drill holes at exactly 90 degrees.

Well made, easy to use
Very solidly made. Pretty simple installation and adjustments. I suggest making a drill block to make sure the back ends go as squarely into the stud as possible. It requires a 21/64 bit, but I don't have one of those on hand, so used a 5/16 (20/64), and it worked just fine. I used drywall anchor inserts for the screws that hold the whole thing against the wall, but they didn't appear to do much...some of them just pulled out of the wall because there was nothing to hold the in considering the amount of space between the screw head and the anchor. Either way, they made for a tighter fit for the screws.

Great shelf support - but watch the small parts.
These pieces work well and have some nice design features. With rods going into the studs and into the shelf, there is a good deal of support. The reason I give it 4 stars instead of five is that the small parts are difficult to maneuver, especially while attaching the hardware to the wall. These small parts work well once they’re in. But getting them to the right place can take some disgusting.
Hanging 3 shelves took a few hours to measure, chisel out the back and hang.

Heavy duty
These are great for thicker boards but not your usual 3/4 boards. I have used others that are smaller but don't see them at Rockler.

Nice product. It would be nice if there were a small amount of lateral adjustment. I was installing a mantle that was ~6 ft long. It can be difficult to get all of the posts necassary for that span perfectly placed.

Chose to make a hidden shelf. This set is suppose to hold the most weight. Looks to be a little more complicated to install but should be worth the effort to gain the extra weight capacity. Time will tell the effort is worth it.

Only blind shelf supports I use. Period!!! Unless I make them and it costs more and is more time and stress.

To mount an 11-1/4" shelf. The light duty/standard blind shelf supports are only good for an 8" shelf max according to Rockler website?

for my need to install a heavy duty floating shelf on dinning room wall
John R on Jan 18, 2018
I will be using these to support kitchen shelves which will need a good load capacity to hold stacks of dishes and such. Also, I wanted the ability to adjust the brackets, if needed, in order to get the shelves to sit correctly. These brackets were the only ones that I found that have both load capacity and adjustability.

It would really help if you included the install instructions along with your description of the product. That would provide answers to questions like "how do the tilt adjustment screws work?" or just "how are they installed?". Information is power and helps to make decisions. Thanks!

BEST ANSWER: There's a video on YouTube for it, just look it up by name in the search bar :)
I assume you drill a hole for the post into a stud. So the side screws just go into drywall?
Tyler V on Nov 27, 2017
BEST ANSWER: Yes - note that drywall anchors are not included, however, so you will need to provide your own.
Iā€™m guessing that a long mortice is needed in the back edge of the shelf for each bracket to conceal the hardware and make it flush ā€“ ā€“ is that correct?
Allen B on Nov 7, 2017
BEST ANSWER: You could put a mortise at each post location, but the gap is fairly small anyway so it isn't that noticeable. It also allows for any irregularities in the actual wall or textured walls.
What constitutes a pair?
Dave S on Oct 22, 2017
BEST ANSWER: One order of item 59434 is a pair, what you see in the photo. That means the pair supports up to 125lbs
Can these be installed in a brick wall?
Valeria P on Nov 6, 2017
BEST ANSWER: They should be able to be installed in brick, you will need a drill bit that can drill into brick to mount the plate
How long is the rod that inserts into the wall/stud for support?
Tbird on Feb 5, 2018

Is there a set screw required for the post that goes into the shelf to prevent slippage over time?
Ralph B on Dec 28, 2017
BEST ANSWER: No there is no set screw although I had wondered why there wasn't, you would have thought there would have had one.
My problem with those brackets is you need a 5/8" drill bit which they don't tell you.
I bought the extended 1/2" drill bit thinking this would work but it didn't.
Good luck.
Does each bracket use 1 stud or do you have to have 2 studs side by side ?
John M on Jul 1, 2018
BEST ANSWER: Each bracket uses one stud, but they recommend not skipping more than one stud between them, so if your shelf is longer than 34" or so you will need more than one pair.
i like the look of plywood end grain and wanted to laminate 2 pieces of baltic birch 3/4in plywood (total thinkness 1.5") that are 15" deep and 48" length for a shelf instead of just a one piece of hardwood, e.g. oak this mounting hardware work on my laminated plywood shelves?
mike g on Jun 21, 2018
BEST ANSWER: This should work as long as you're using very good glue to laminate. There will be a tendency of the hardware to want to split the lamination over time.
