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

Minimum shelf length for heavy duty supports incorrect
The 18" minimum shelf length for the heavy duty supports should read 20" in my opinion. Compare the pictures of the brackets of the light and heavy duty and the heavy duty ones are wider as compared to the light duty. To be truthful if you want the brackets to not be visible at all I'd go 20 !/2" or the end of the mortises will be very close to the end of the shelf. So I need to modify or redo my shelves at present. The heavy-duty brackets seem to be very strong and well built with no bending or flexing apparent. Then again I have not installed them. Wanted to get the message out on the shelf length error.

Woodworking Experience:
Worst product ever
I purchased two sets of these heavy duty brackets. The support going into the wall was very tricky. There are two screws supplied that hook the bracket into the wall. Although the instructions call for drilling the stem into the stud, the spacing of the screw supports are 3" apart. This guarantees that the screws can only go into the Sheetrock! The location of the bar going into the shelf is very critical. Any mismatch to the separation will result in nothing fitting. Also there are adjustment screws for the alignment but it is hit or miss. You cannot adjust withe the shelf on so you have to repeatedly take the shelf off and on to correct. Since the fit is very tight there is no play for this type of adjustment. Also, the supports stand out approximately 3/8" requiring a motise to be made to hide the hardware. After mounting the first shelf, the second set has gone into the trash, It was not worth the effort to return it. I would give this product no stars if that was possible.

Woodworking Experience:
Not great
Not as strong as advertised, post that goes into stud can easily be bent by hand, in fact was bent out of package and way too easily bent it back, was actually concerned it would break off when I did so. The only mounting holes for screws into wall are beside the stud, not in it, so only actually mounted with drywall anchors... some side to side adjustability would be a good addition. Was frustrating to do all the work to mortise the shelves for them, just to get done and have floppy shelves. I'm a veteran finish carpenter/cabinet maker with many years experience with residential and commercial hardware.

How long is the rear peg support that goes into the stud?
GreenTree B on Mar 9, 2019
BEST ANSWER: The rear (wall) stud requires a mounting hole 12/32" x 3-1/8" deep.
Can these be used in a cinder block wall?
