Bsc Preferred LK348 Sink Mounting Screw Clamp Set 12-piece

Product Description

The BSC PREFERRED LK348 is a 12-piece sink mounting hardware set consisting of installation screws and clamps designed for J-channel drop-in sink installations. The hardware secures the sink deck flange to the countertop, creating a stable, leak-resistant mount. Countertop compatibility extends to 2 inches thick. This set is installed by licensed plumbers and skilled trades during new construction or remodel work in kitchen and bathroom applications. Each piece is purpose-built for the J-channel clamp style common in undermount and drop-in sink configurations.

The LK348 hardware set is suited for residential kitchen and bathroom sink installations as well as light commercial countertop sink applications. It is typically used when replacing a sink or installing a new drop-in unit in a laminate, stone, or solid-surface countertop up to 2 inches thick. The J-channel clamp design allows the installer to draw the sink flange tightly against the underside of the countertop deck without requiring adhesive alone as the primary fastening method.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson. Shut off the water supply and disconnect the drain assembly before removing or installing the sink. Use a screwdriver or nut driver to tighten the clamps evenly in a cross pattern to distribute clamping force uniformly across the sink flange. Do not overtighten, as excess force can crack the countertop material or deform the sink flange.
