Our HD Front Mount Countertop L Bracket delivers heavy-duty, worry-free support for granite countertop overhangs extending from kitchen islands, cabinet bases, knee walls, pony walls and more. Engineered with a welded center gusset that eliminates bracket flex, each bracket carries up to 350 lbs. so you can confidently support even the heaviest stone, quartz, or concrete surfaces knowing the support beneath is as solid as the countertop itself. The low-profile front-mount design keeps brackets tucked neatly beneath your countertop for a clean, professional look, and the straightforward installation means both seasoned contractors and first-time DIYers can get the job done right with nothing more than a drill and the included hardware.

Built for Strength, Designed for Simplicity. Our brackets are forged from solid 1/4" thick A-36 HRPO American Steel, the same heavy-duty structural-grade material used in commercial and industrial applications. The welded 1/4" center gusset is the difference between a bracket that flexes and one that doesn't. Under load, this bracket stays perfectly rigid, no sagging, no shifting, no movement. Period. Available in five sizes from 10" to 20" deep and finished in durable Matte Black or White powder coat. The HD Front Mount Countertop L Bracket handles granite, quartz, concrete, natural stone, wood, Formica, and every other countertop material you can put on top of it.

Specifications at a Glance:

  • Material: Solid 1/4" A-36 HRPO American Steel with 1/4" Welded Center Gusset
  • Width: 2.5"
  • Sizes: 10" x 6", 14" x 7", 16" x 9", 18" x 10", 20" x 12" (Depth x Height)
  • Mounting Holes: 12 pre-drilled holes per bracket — 6 rear countersunk holes (Ø.270") for #14 x 2½" Phillips Flat Head Wood Screws (included), plus 6 top through-holes for optional countertop fastening (hardware not included)
  • Finish Options: Matte Black powder coat, White powder coat
  • Load Capacity: 350 lbs per bracket

Important Note on Load Capacity: The stated carrying capacity of 350 lbs per bracket is achieved only when the bracket is properly mounted to a solid, structurally sound substrate using the included hardware. Brackets must be anchored into robust materials like 2x4 or 2x6 lumber framing or 2x12 backing ensuring adequate embedment. Fasteners should be torqued to a firm, secure hold, avoid over-torquing, which could compromise the integrity of the substrate or the fastener itself. Always follow the installation guide and consult a professional for load-bearing applications or if you are unsure about your substrate's capacity.

Key Product Advantages:

  • Heavy-Duty Support: The welded 1/4" center gusset provides rigid, structural-grade support that eliminates bracket flex so your countertop stays perfectly stable under load.
  • Exceptional Load Capacity: Each bracket supports up to 350 lbs when properly installed, with FEA-validated structural analysis confirming the bracket remains within the elastic range of the steel at rated load.
  • Premium American Steel: Crafted from solid 1/4" A-36 HRPO American Steel for maximum longevity and structural integrity, this is not lightweight imported sheet metal.

Size & Quantity Guide

Our recommendations meet or exceed the general guidelines provided by the Natural Stone Institute (formerly MIA) for safe and effective countertop support. While natural stone and exotic materials can be unpredictable, and man-made solid surface tops may require less support, our recommendations, based on extensive experience, offer a higher level of structural integrity and peace of mind compared to the minimum guidelines for unsupported overhangs.

What Size Bracket Should I Use?

Ideally you want no more than 3" of unsupported countertop extending past the end of your bracket. Here's how to figure it out:

  • Measure Your Countertop Overhang: Determine the depth of your countertop overhang — the distance from the face of your cabinet or wall to the front edge of the countertop. (e.g., 19 inches).
  • Subtract Your Bracket Setback: Allow 3" of countertop to extend past the end of the bracket.
  • Select Your Bracket Size: Choose the bracket depth closest to your result.
    • Example: For a 19" countertop overhang:
    • 19" Overhang − 3" setback = 16"
    • Recommended Bracket Size: 16" x 9"
  • Available Sizes: 10" x 6", 14" x 7", 16" x 9", 18" x 10", 20" x 12"

Note: Our brackets are listed as depth x height measurements. The first number (depth) supports your countertop horizontally. The second number (height) mounts to the wall or cabinet face vertically.

How Many Brackets Do I Order?

For optimal stability and weight distribution, these brackets should be placed every 16 to 24 inches apart, ideally aligning each one with a wall stud for maximum strength. To figure out exactly how many you need:

  • Step 1: Place End Brackets — Install one bracket 4" in from each end of your countertop. (This accounts for 8" of total width.)
  • Step 2: Measure the Remaining Span — Subtract 8" (the space used by the two end brackets) from your total countertop width.
  • Step 3: Divide by Your Desired Spacing — Divide the remaining span by your chosen bracket spacing (16" or 24"). Drop the decimal — the whole number is how many additional brackets you need. The decimal remainder just means your actual spacing will be slightly tighter than the target, which is always the safer direction.
  • Step 4: Add It All Together — Add the 2 end brackets to the number from Step 3.

Example: For an 84" wide countertop with 16" bracket spacing:

  • 84" − 8" (end brackets) = 76" remaining span
  • 76" ÷ 16" = 4.75 → drop the decimal = 4 additional brackets
  • 2 end brackets + 4 additional = 6 brackets total

Recommended Bracket Quantity Table

Countertop Width Qty @ 16" Spacing Qty @ 24" Spacing
24" 3 2
36" 3 3
48" 4 3
60" 5 4
72" 6 4
84" 6 5
96" 7 5
108" 8 6
120" 9 6
🛠️ Got a custom size countertop like 91.75" or something in between? No worries! Just use the 4-step formula above — it works for any measurement. When in doubt, add one more bracket. Extra support never hurts, and our brackets are affordable enough that it's always better to over-support than under-support.

Love this bag, wish it was even bigger!
Color: Sorrel
This is a nice squishy pebbled leather crossbody tote. I'm using it as a work bag BUT it won't fit a 16 inch laptop so if that's a consideration skip this one. It does fit a 10 inch iPad and Kindle, plus a compact umbrella, wallet, over ear headphones, full size body spray and lotion, big pack of gum, several lip products and dental floss, mini hand sanitizer, small brush, pens and a notebook... So basically my whole life fits in it aside from my laptop. It smells like leather, and I love that. The brown color has lots of variations so it looks like it has a patina already. I sprayed it with Apple Garde for waterproofing and it didn't affect the feel or color of the bag at all. This bag is really pretty and I get compliments on it daily. The zipper seems sturdy and never catches or gets stuck. It molds itself to my body like a softer leather should and I would say that it's absolutely worth the price. The strap is wide, sturdy, and comfortable too. There are multiple pockets on one inner side, a zippered middle compartment, and a zippered side compartment on the inside as well, along with an outer pocket so there's plenty of organization without having to buy an insert. I wish they had this available in an even bigger size to fit a standard laptop!

Expectations not met re. bag!
Color: Navy Blue
The seller was fantastic, as he/she accepted my return and refunded me immediately. Seller gets 5 stars. Even thou this bag is a stunning Navy Blue, BEAUTIFUL stitching, beautiful zippers and liner, wrapped professionally with TLC, I could not stand the very strong smell. I don't know if the smell was due to the navy blue color/dye or not. I can't even describe the smell... besides that it's not leather. I was gifted the same bag in "light brown" and that bag smells like leather; it's like you are in Rome shopping for the real thing! I love that bag as I can wear it crossbody, shoulder or hand held. Unfortunately, it too small for me. So I thought, if I am buying bigger, let's do the dark blue. Was I wrong. I really had high expectations for this bag. :0(

So thought I would give this purse a try. Never bought anything like this on Amazon. My much much more expensive designer brand had to be replaced. I really like this purse. It’s the perfect size and very nicely made

So cute and dressy. Fit well and bought 1/2 size smaller than usual.
I usually wear sneakers and wanted shoes that were a bit dressier for going out for dinner with my husband. I usually wear a size 7 but bought these in a size 6 1/2 as recommended. I tried them on with bulky wool blend socks that I normally wear, and they fit perfectly. Since I intend to use these boots for dress, I didn't wear them for a long period of time, but found them to be comfortable, and the heal was not too high. The top of the boot is high enough, that it would still be covered by pant legs when you sit down. I also like that the zipper opening in the side made them very easy to get on and the zipper worked very well without sticking. I also like the stacked heal vs. a higher, thinner heal. Although I used to wear 3" spike heals when I was younger, I am now 77 years old, I am more comfortable and feel safer with a thicker heal. Overall, I very much like these ankle boots, and would recommend them. I hope this review is helpful for you.

Amazing boots!
These boys are gorgeous visually, then when you put them on you can feel the cushioning inside. So comfortable! There is plenty of room in the width, I take a 7 and it for perfectly without being tight with sock on. Outside feels so soft to touch, can't believe quality for the price!
