Review Star RatingsNot attractive, but functional
by: JC   Verified Buyer      from: Jax, FL      on: June 11, 2020
 They are exactly as presented. These brackets use a very basic design. Two brackets can support a heavy floating shelf. Also using four brackets to float a large 24" x 80" desk against a masonry wall. Not particularly attractive, but the paint finish is good.

 Used 3 brackets to hold a 5’x25” granite countertop without cabinets underneath. Feels solid, I believe the screws in the studs would fail before the brackets ever would.

 These brackets are beast! I used six to hold up a 13 foot by 32 inch workbench that hold my router, miter saw, and drill press and six drawers full of stuff.I figured they may sag a bit, but nope. The support bar did fall out of one when installing, but gravity holds it in place no problem.

Review Star RatingsGreat for installing floating desk
by: Robert   Verified Buyer      from: Orlando, Fl      on: February 24, 2020
 I bought five of the 22" brackets because I wanted to mount a 98" IKEA Karlby countertop which weighs about 90lbs to a wall without needing the support of adding legs so I could use it as a desk. These worked fantastically for my project. I mounted them into a concrete wall for extra supports using a Lag Bolt Kit for Mounting A TV from amazon And then I used #10 1.75 inch screws to drill into the underside of the countertop. Overall, I am very pleased with the purchase and would do so again if needed.

Review Star RatingsVery Satisfied
by: Dan   Verified Buyer      from: Easthampton, MA      on: January 14, 2020
 I used these wall brackets to support a 6 Ft x 2 FT counter that I am using as a computer desk. They worked out exactly as I had hoped. The counter top is steady and secure.

Review Star RatingsIt’s not square
by: Sandalio Lopez   Verified Buyer      from: Westbury, NY      on: January 9, 2020
 It’s well constructed and strong, but it’s not square. I have to shim it up in such a weird way to make it level to either the wall or counter. If I wasn’t in a hurry I would ask for an exchange, but the integrity is sound where it will hold the counter to the wall.

Review Star RatingsNice heavy duty bracket
by: Judy   Verified Buyer      from: Clarkston, WA      on: March 29, 2019
 Very heavy duty bracket in a length I couldn't find anywhere else. Only complaint was that the offset screw holes made it difficult to hit the studs in our drywalled garage. We had to resort to screwing 2 x 4's onto the wall to be sure we didn't miss the hidden studs.

Review Star RatingsJust what I expected
by: Melissa Ramstetter   Verified Buyer      from: -, Oh      on: March 13, 2019

 These worked perfectly for mounting 3/4 in. wood shelves across the back wall of my framed shed. The screw holes are perfectly placed for drilling into the sides of standard studs.

Ask a questionI am having a computer work station put in our kids loft area. The counter will be 1.25" wood that is 100" long X 20" deep with no side supports only brackets anchored to studs. I am wondering if the Hafele Super Duty Ultimate L-Bracket is the right bracket to use for this purpose? The work surface would most likely hold 3 computer monitors. My concern is will it hold those as well as kids/teens leaning on the shelf as well? Or do I need to look at a more substantial bracket?   - Asked about product HA-287.55.763
 AnswerThis bracket will hold up to regular wear and tear and up to1200lbs.
The bracket is designed for just such an application work surfaces that will support the load of things like computers. Just be sure to order the corresponding width bracket versus the width of the countertop which, MUST BE MOUNTED ON THE STUDS with the proper quantity and length screws. Screws are needed to mount the bracket and screws are also, needed to connect the support to the countertop.
