Sink Setter 25 to 47 kit is an adjustable sink support system designed for undermount kitchen sink installations. The PW-104-P model adjusts from 25 inches to 47 inches in length, so one kit works across a wide range of cabinet spans. This size works well in wider cabinets and islands, letting you bridge larger openings without custom fabrication. It also supports side-to-side installations, giving flexibility in how the sink is oriented under the countertop. The kit is designed for single bowl or double-bowl stainless steel sinks, so one setup can serve common kitchen sink layouts. It also works with any cast iron sink and composite sinks used in an undermount kitchen sink installation, covering typical residential sink materials.
The PW-104-P Sink Setter can be installed after the countertop is installed, so the support system can be added during final trim rather than rough-in. Adjustable length from 25 inches to 47 inches lets the bars position within the cabinet to match the sink location, whether centered or offset in a wider run. Side-to-side installation capability means the bars work across the cabinet width, providing a support frame directly under the sink body. Using heavy duty bars with leveling bolts allows vertical adjustment of the sink position during undermount kitchen sink installation, helping align the rim tight to the countertop. The same kit working with stainless steel, cast iron, and composite undermount sinks simplifies planning across different kitchen sink choices.
The Sink Setter PW-104-P adjustable sink support kit is designed to work where cabinet spans vary from 25 inches to 47 inches, so one product covers many base cabinet widths. In wider cabinets and kitchen islands, this adjustable range allows the bars to bridge between cabinet sides even when factory rails sit farther apart, giving a firm support frame under the sink. For side-to-side installations, the bars can run laterally across the cabinet, placing support exactly where the sink body needs bearing. This flexibility helps when layout decisions place the sink off-center within a run, because the adjustable length lets the bars match the actual spacing. In an undermount kitchen sink installation, being able to set the bars relative to the finished countertop opening helps the installer align support points directly beneath the sink flange area for consistent bearing.
The adjustable 25 to 47 inch span works with single bowl and double-bowl stainless steel sinks, so one setup can handle different basin configurations while keeping the same support approach. Compatibility with any cast iron sink and composite sinks in an undermount kitchen sink installation extends that same method to heavier and non-metal basins, which benefits projects using varied materials across multiple kitchens. Two heavy duty bars provide a broad contact surface under the sink, helping distribute the load rather than concentrating it at a few points. Leveling bolts within the kit give vertical adjustment at the support points, so the sink height can be fine-tuned to meet the underside of the countertop evenly. Because the PW-104-P Sink Setter can be installed after the countertop is installed, the installer can set support and height based on the actual cutout and sink position, helping achieve a uniform reveal and reducing rework.
The Sink Setter 25 to 47 kit adjusts from 25 inches to 47 inches in length, so it spans cabinet interiors and sink locations that fall within that range.
The Sink Setter PW-104-P is useful in wider cabinets and islands or when side-to-side installations are needed, because the adjustable bars bridge those wider spans.
