Karran Profile stainless steel kitchen sink identifies this unit as a Karran Profile 31-1/2 inch wide stainless steel undermount kitchen sink with a double 50/50 bowl layout, so installers get a matched pair of equal bowls for consistent workflow at the sink line. The sink is classified by the manufacturer as a stainless steel sink, which defines its role in kitchen projects where a metal basin is preferred over other materials. It is designed for undermounting, so it fastens beneath the countertop edge and leaves a clean, exposed counter reveal for easier wipe-down around the bowls. The undermount design is specified for use in granite, quartz, and solid surface countertops, which targets typical hard-surface kitchen installations. With an overall width of 31-1/2 inches, the unit suits base cabinet layouts sized to accept that span. The manufacturer part number PU51 provides a precise identifier when matching specifications on drawings or reorders.
The sink is described as used for undermounting in all granite, quartz and solid surface countertops, so its rim and bowl geometry are intended to hang from below rigid tops common in kitchens. That undermount callout means the bowl edge sits under the counter material instead of on top, leaving the upper surface of granite, quartz, or solid surface fully exposed around the cutout. This configuration supports a flush wipe from the work surface straight into either of the two equal bowls without a raised lip interrupting the line. Because all external dimensions are noted as approximate to 1/4 inch, installers have a tolerance window when laying out cut patterns and aligning the sink to the front and sides of the cabinet opening.
The SAP description lists this product as PROFILE SS KITCHEN SINK,UMT DBL EQ 16G, which defines it as a Profile series stainless steel kitchen sink with an undermount, double equal-bowl configuration, making it suitable for layouts that call for two same-size working basins. The web description notes it is used for undermounting in all granite, quartz and solid surface countertops, so it is applied in kitchens built with these rigid surfacing materials in both new construction and remodel work using those tops. With a stated width of 31-1/2 inches, the sink fits projects designed around a counter and cabinet space that can accommodate that overall span in the sink base. The manufacturer part number PU51 and the replacement reference to old WBSC part number KAPU21N together help specifiers and installers line this sink up with previous drawings or part schedules that may reference either number.
The description identifies the layout as a double 50/50 bowl, so each side is equal, which simplifies faucet and accessory hole planning along the counter because the center line of the sink stays balanced between the two bowls. The product is defined as a 16 gauge stainless steel sink, so the bowl walls and deck use that gauge, giving a consistent material thickness that supports undermount clamping and sealant compression around the edge in a typical hard-surface countertop application. The note that all external dimensions are approximate to 1/4 inch sets a defined tolerance band for fabricators when aligning cutouts and reveals, helping them coordinate the sink outline with the actual counter opening. The replacement mapping to old WBSC part number KAPU21N means projects originally drawn with that earlier reference can transition to PU51 while maintaining the same intended sink identity in the specification set.

The PU51 sink is made from 16 gauge stainless steel, which defines a substantial stainless body suitable for typical kitchen sink use.
All external dimensions for this stainless steel undermount kitchen sink are approximate to 1/4 inch, giving fabricators a stated tolerance when planning cutouts.
The PU51 is listed as a replacement for old WBSC part number KAPU21N, so it occupies the same role where that earlier reference was specified.
The Karran Profile PU51 sink is defined as a 31-1/2 inch wide stainless steel undermount kitchen sink with double 50/50 bowls in 16 gauge stainless steel, so it aligns with hard-surface countertop kitchens needing equal-bowl functionality. Its use for undermounting in all granite, quartz and solid surface countertops positions it directly in common residential and similar installations using those materials. With clearly stated material, gauge, layout, and part-number continuity from KAPU21N, this sink offers a defined specification target for fabricators and installers planning consistent undermount work.
