Standard Bracket image

Standard Bracket

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".

Standard Plus Bracket

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".

Forward L Bracket image

Forward L Bracket

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.

Island Bracket image

Island Bracket

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.

Island Support System image

Island Support System

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.

Spanning Bracket image

Spanning Bracket

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.
