Item details

The L-Bracket metal angle supports for countertops gives virtually invisible support to granite, quartz, marble and other natural stone or heavy kitchen countertops.

Note: This bracket MUST be used with a knee or pony wall or inside a cabinet reinforced with a 2x6. If you are looking for a bracket for shelving we have those as well; this bracket is not intended for shelving.

When installed this steel countertop bracket provides an open space for chairs and leg room, meaning you no longer need to use bulky wooden corbels.

This support bracket gives additional support to your kitchen countertop especially when you have an overhang on a bar top that is deeper than the standard 12 inches or for a bar top which is very long and will be seating 4 or more people.

This steel bracket can be used even when there is no knee wall or pony wall.

Watch how to install our L Bracket and tips before buying:

The L Bracket is a low profile, non-intrusive support bracket made of 1/2 inch thick by 2-1/2 inch wide American steel on the horizontal piece [see listing for length] and the vertical piece [tang] is made of 1/4 inch by 2-1/2 inch X 6 inch long wide American steel protected with a high quality anti-rust black paint.

Although we have standard sizes we can manufacture special order brackets with specifications to your request. We have a full custom fabrication shop and can build any steel support bracket for your custom needs.* We are proud to say all of our brackets are made in the USA.

Horizontal Piece Dimensions:

Length ……..…. [see listing]

Width …………. 2 ½ inches

Thickness …..…. ½ inch

Countersunk Hole Diameter… 1/4 inch

Vertical Piece [Tang] Dimensions:

Length.......6 inches [do not include this piece in determining what length to use]

Width …………. 2 ½ inches

Thickness..... 1/4 inch

Hole Diameter.....1/4 inch

How to Determine What Length to Use:

Brackets are sized in length tip to tip horizontally; therefore a 9 inch bracket is 9 inches tip to tip horizontally. [do no use vertical tang in measurements]

When determining lengths stay sway from outer edge 3 inches and do not forget to add in the thickness of the knee/pony wall or the 2X6 inside the cabinet.

Example of how to determine the size L Bracket you will need:

If you have a knee/pony wall: (see pictures in top of listing) Let's say you have a 12 inch overhang, plus 4 inch in the knee/pony wall, equals 16 inches, minus 3 inches outer edge, means you would need a 13 inch L-Bracket.

We recommend placing an L Bracket on each stud in your knee/pony wall for maximum countertop protection.

If using a 2x6: (see pictures in top of listing) Let's say you have a 12 inch overhang, plus 1 1/2 inches for the 2x6, plus 1/2" {measure your cabinet this is an example} for the thickness of the back wall of your cabinet, minus 3 inches outer edge, means you need an 11 inch L Bracket.

We recommend spacing your brackets 20 inches apart when using a 2x6 for maximum granite protection.

Note: We do not recommend using the L Bracket for shelving, this bracket is designed to be used inside cabinets or over knee/pony wall for coutnertop protection. For shelving we recommend our Regular Shelf Bracket or Large Shelf Bracket.


The L Bracket can be installed to a knee/pony wall or into the back of a cabinet.

If installing into the back of a cabinet a 2X6 must be installed to the inside back wall of the cabinet first then the L Bracket attached to the 2x6. The L Bracket is to be mounted to a strong foundation in order to protect the weight of your countertop.

When installing into a knee/pony wall it is important to hit the studs in the knee/pony wall in order for the L Bracket to be mounted to a strong foundation to protect the weight of your countertop.

Steel is a natural material. When welding it together some “pull” will naturally happen. As with all construction, there are no perfect lines or angles. Though we do everything we can to make sure the brackets are as perfect as they can be without compromising the integrity of the steel’s strength, some brackets may not be a perfect line, perfect angle or perfectly level. Therefore, as in most construction, you may have to shim when installing some of the brackets. Note: By purchasing our brackets, you agree to these terms and understanding.

Have a question? Our family has been in this industry for years. We owned a Kitchen and Bath Design Center and have owned a granite fabrication and installation business; plus been in construction of over 35 years. That is why we designed these brackets. All other steel brackets on the market are not strong enough. Ours are the strongest and the original! We have been imitated but not duplicated. We are here to help.
