Elkay LKUMSK36 Undermount Sink Support Kit 36 in

Product Description

The ELKAY LKUMSK36 is an undermount sink support kit designed to anchor undermount sinks securely to cabinet walls during installation. The kit includes rails measuring 36 inches in length that can be cut down to fit the specific cabinet dimensions of the project. This hardware is used in kitchen and laundry room sink installations where the sink must be held firmly against the underside of the countertop without movement or settling over time. Plumbers and finish carpenters typically install this type of hardware as part of a full undermount sink rough-in. The kit weighs 2.3 pounds and ships in packaging measuring 39.5 inches by 2.5 inches by 2.5 inches.

The LKUMSK36 is suited for residential kitchen and laundry installations where an ELKAY undermount sink requires positive mechanical support from the cabinet structure. The adjustable rail length makes this kit adaptable to single-bowl and multi-bowl cabinet configurations. It is particularly useful during new construction and remodel work where cabinet dimensions vary and a field-cut rail length is needed to achieve a clean, secure fit. No special fasteners beyond standard cabinet-mounting hardware are required in most applications.

Key Features

• Rails are 36 inches long and field-cuttable to match actual cabinet width
• Mounts to cabinet wall to provide structural support for the undermount sink
• Lightweight at 2.3 pounds, reducing handling burden during overhead installation
• Sold as a single kit (quantity: 1) for straightforward ordering
• Non-hazardous materials for standard jobsite handling

Compatibility

Designed as an OEM-style undermount support accessory for use with ELKAY undermount kitchen and laundry sinks where cabinet wall rail support is required during installation.

Installation Notes

Installation is typically performed by a licensed plumber or skilled finish carpenter as part of an undermount sink rough-in. Shut off the water supply and ensure the countertop is not yet set or is fully supported before mounting support rails to the cabinet interior. Cut rails to the required length using a hacksaw or metal-cutting blade before securing to the cabinet wall. Follow local plumbing codes and the sink manufacturer's installation instructions for fastener type and spacing.
