Countertop Support Bracket 20 inch 4 Pack (3/8" Thick),Premium Heavy Duty Granite Countertop Brackets 20"x8"x2.5",Shelf L Bracket Mantel Corbels for Quartz,Wood,Concrete and Laminate Countertops

Heavy duty, nice fit/finish, did not disappoint. Excellent buy compared to “Big Box Store” options and pricing.

Man, these things came in and they were super heavy duty. When you talk about quality, they were super thick and heavy. I was actually surprised because I didn’t know if we can install them because they were so heavy. I was using them to hold up a countertop. The quality and thickness and the power coating is very good and sturdiness. We use them to support a countertop that was overhanging a cabinet with the sink. Functionality I don’t know about long-term but right now they are still holding and everything looks OK. I think the value is OK for what I paid for. They’re not exactly cheap, but they do the purpose and support the countertop.

Extremely solid-and great value!

Very strong and sturdy. Perfect for my work bench. I will say that I ran into a couple issues. One of the supports was 1/4” lower at the long end than the others. I understand the complexity of welding thick steel and heat-induced warpage but this one shouldn’t have gone out the door with the others outside of that, they work well and lined up well. The drywall mounts are worthless. They don’t hold their place as the screw is tightened and yes, I’m aware of how to use thiat type of mount. Outside of those issues, they are strong and hold my work bench well.

These are HEAVY thick L brackets that you'd pay $50-90 (depending on size) ea at home supply stores. My island was previously a little smaller without an overhang, but I added a matching cabinet on one end and really wanted a eating bar, so bought a used granite top the was the perfect size I needed. I used these brackets to support under the 12" overhanging bar area on my newly now extended kitchen island. After measuring, it took all four of these for my 5ft bar. You put one 6-8" from each end and then one every 12 -18" in from each outter brackets. DON'T skimp out on properly supporting your overhang bar or shelf else it will warp, crack and could break loose! I already had the bigger granite top on my island with a slight over hang on both long sides, so I needed these put in asap. It took three men and myself to bring this top in and place it on this island. Had to install the brackets a few days later by myself. I slid the granite top over to put in the first two brackets. Then slid top over the other way, over on top of the two new brackets for support, while I put in the other two brackets. I had to do some notch out cutting to make the brackets level with the island cabinet and put in 3/4" boards to screw the brackets and inside of the island cabinet together to properly support the lower leg of each L bracket. IF done this way, unless you look under the overhanging bar, the brackets are hidden and you save ruining the outside of your island cabinet. FYI: There are many videos online showing how to install these. I may buy another set later and put up some heavy duty shelves using heavy lumber.
