Support Brackets

If you're looking for a product that provides hidden countertop support and is easy to install, then look no further than the Standard. Designed to mount on the top of a pony or knee wall, the standard bracket is a general-purpose bracket.


Hidden from view, the bracket serves as a sleek, modern support for any overhang. Its low profile ensures you and your guests don't have to worry about knocking your knees on large supports.


Made of 1/2" thick steel, the Standard is designed to hold a great deal of weight and can support an overhang up to 18".

Centerline's Standard Plus hidden countertop support bracket is a versatile product that can be used as a knee- or pony-wall support or as an island countertop support.


The Standard Plus countertop support differs from the Standard in that it has a 11/2" flange on the back of the bracket. The rear flange wraps down the backside of the knee or pony wall and provides an extra contact point for securing the bracket.


Made of 1/2" thick steel, this sturdy bracket can support an overhang up to 21".

The Forward L countertop support is the best choice for a commercial environment, in areas with a high volume of traffic, or if supporting an overhang of 18" or more. This bracket provides extra mounting points on the flange that allows the bracket not only to be attached to the cap of the knee or pony wall, but to the vertical studs as well.

For the always-popular island or peninsula, the Island countertop support is a great choice for supporting heavy countertops such as granite, quartz or butcher block. The bracket is designed for an application where no knee wall exists and the countertop extends directly off the base cabinets.


Created with ease of installation in mind, the bracket attaches to the inside of the cabinet face frame via a steel flange and extends through the cabinet and out the back to support the island overhang. The key to this bracket's strength lies in the cantilever action that uses the weight of the countertop material to ensure a solid structure.

Floating an overhang on more than one side of an island or peninsula requires an innovative solution and the Island Support System fits the bill. This unique system uses lap joints to create a custom bracket specific to the kitchen's design.


Once mounted, the countertop support creates a cantilever, leveraging the weight of the countertop as well as the 1/2" steel. It's a perfect bracket for multiple overhangs.

The Front Mounting Plus countertop support bracket is designed for use in high-traffic or load applications such as commercial environments, shower benches or free-floating desks. This is achieved by the addition of a low-profile gusset that substantially increases the load rating on the bracket. It can be used to support an overhang up to 24".

This bracket mounts directly to the stud and also can be hidden from view.

The Center Levered support is designed for use when you have countertops that extend on both sides of a knee or pony wall. It is also an ideal solution for use in commercial locations such as bars or with offset overhangs.

Steel flanges provide additional stability to the bracket and can be repositioned to fit your project.

Just as the name implies, the Spanning Bracket is used when support is needed for a span of countertop where there's support on both ends, but nothing in between. This bracket is perfect for creating a floating desk between cabinets.

The Spanning Bracket is also used where you have overhangs on opposite sides of a support cabinet. If you have an overhang on three sides of a cabinet the spanning bracket can be substituted in the island system to provide support.

The Floating Wall Mount creates a sleek and seamless look for countertops and can be used in many environments. This versatile bracket, designed to affix to the side of a stud within the wall, has the ability to float vanities, countertops, benches and shelves directly off the wall.

Cleverly hidden behind the wall, this sturdy bracket is the perfect way to achieve an open, free-floating look so popular today.
