Four Independent Support Points

DuraLedge HD supports the sink from below at four independently adjustable locations. Each steel bracket can be positioned separately to work with the actual sink and cabinet layout, rather than spanning the cabinet with a full-width support platform.

Depending on the installation, this can preserve useful room for plumbing, garbage disposal access and cabinet storage while keeping final sink height adjustment accessible. Actual fit and clearance depend on the sink, cabinet and plumbing layout.

A Cleaner Alternative to Field-Built Support

Farmhouse and apron-front sinks commonly require support from below. Wood framing can work when properly designed and installed, and some sink manufacturers specifically require cabinet framing.

Field-built support may involve measuring and cutting onsite, fitting around plumbing and disposal locations, fastening inside a finished cabinet, and shimming to establish final sink height. A support platform can also take up useful cabinet space.

DuraLedge HD provides four independent adjustable steel support points without requiring a bulky full-width wood platform across the cabinet: purpose-built sink support, accessible final height adjustment and a repeatable installation method.

Developed in a Working Cabinet Shop

DuraLedge grew out of a recurring problem in a custom cabinet shop: farmhouse sinks needed support before countertop templating, and the solution often had to be built in the field inside a brand-new cabinet.

The goal was a cleaner, repeatable support method that made sink positioning easier while leaving more of the finished cabinet usable for the homeowner and the trades that follow.

Fit & Installation Support · Installation Planning

Cabinet guidance

Some face-frame cabinets have a hollow space or thinner area near the front of the cabinet side. If the bracket fastener passes through one of these areas, add solid material behind the cabinet wall before tightening. This is a cabinet-preparation step that can apply to through-wall sink support hardware generally.

Installation confidence

During final sink placement, apply a small bead of silicone or another appropriate sink/countertop sealant to the top rim of the sink. Raise the sink only until it is snugly and evenly seated against the underside of the countertop.

Installer Note

The brackets are designed to support and position the sink. They are not intended to press the sink forcefully into the countertop. Raise the sink only until it is snugly and evenly seated against the underside of the countertop.

Built With Cabinet Shops in Mind

For shops using CAD/CNC equipment, bracket mounting locations can potentially be incorporated into the cabinet-production workflow. For conventional construction, the same support system can provide a consistent installation method.

Plan sink support as part of the cabinet instead of improvising it in the field.

Frequently asked questions

How far is the adjustable leveler’s centerline from the cabinet wall?

The centerline of the adjustable leveler is 4.10 inches from the cabinet wall. This measurement is to the center of the leveler, not the outer edge of its pad. When planning around plumbing, a disposal, drawers, or other obstructions, allow clearance around the leveler itself.

What is the DuraLedge® HD Sink Bracket Kit?

The DuraLedge® HD Sink Bracket Kit uses four adjustable brackets to support and position farmhouse and apron-front sinks inside the cabinet.

How much weight is the DuraLedge HD Sink Bracket Kit engineered to support?

Engineered to support up to 400 lb when properly installed.

What types of sinks can DuraLedge HD be used with?

DuraLedge HD is designed primarily for farmhouse and apron-front sink installations. It can be used with fireclay or clay-fired, cast-iron, solid-surface, and stainless-steel sinks.

What comes in the HD kit?

The HD kit includes four DuraLedge HD sink-support brackets, adjustable levelers with locking nuts, and installation hardware.

How is the sink adjusted during installation?

The four brackets provide independent adjustment points for positioning the sink and making the final height adjustment during installation.

How tight should the sink be against the countertop?

The sink should be raised only until it is snugly and evenly seated against the underside of the countertop. The brackets are not intended to force the sink into the countertop. Avoid excessive upward force, particularly with thinner stainless-steel sinks.

Do cabinet conditions matter?

Yes. Check the cabinet walls and make sure you can reach the mounting locations before installation. Some face-frame cabinets have a hollow space or thinner area near the front of the cabinet side. If a bracket fastener passes through that area, add solid material behind the wall before tightening so the walls are not pulled together. This is a cabinet-preparation step, not a problem unique to DuraLedge.

Does DuraLedge replace sealant at the countertop?

Before the sink is raised, apply a small bead of appropriate silicone or sealant to the sink rim. Raise the sink only until it is snugly and evenly seated against the underside of the countertop.
