Alpha International U109 K Series Stainless Steel Single Bowl Undermount Cutout
Description
The Alpha International U109 K Series delivers professional-grade performance in a compact rectangular format measuring 16 inches wide by 18 inches deep. This commercial-quality 304 stainless steel undermount sink features robust 18-gauge construction with a premium brushed satin finish, providing durability and style in space-conscious applications. The 14x16 inch bowl interior offers enhanced capacity compared to the square U103, while the 8-inch depth accommodates bar sink, prep sink, and secondary washing applications. Requiring only a 19-inch minimum base cabinet, the U109 fits island installations, butler's pantries, outdoor kitchens, and wet bar locations where compact dimensions are essential. The DXF template includes four installation variants for fabricator flexibility.

The Alpha International U109 K Series delivers professional-grade performance in a compact rectangular format measuring 16 inches wide by 18 inches deep. This commercial-quality 304 stainless steel undermount sink features robust 18-gauge construction with a premium brushed satin finish, providing durability and style in space-conscious applications.

Installation Overview
Installing the U109 rectangular sink requires attention to orientation and proper alignment within the cabinet opening. The template provides four professional variants: no-reveal for flush bowl edge alignment, 1/8-inch reveal for standard undermount installation with visible rim protection, 1/2-inch overhang for increased countertop support coverage, and drop-in configuration for top-mount applications. The rectangular format allows the sink to be oriented with the 18-inch dimension running front-to-back or side-to-side depending on cabinet configuration and user preference. Most installations position the longer dimension perpendicular to the counter edge for ergonomic access. The 18-gauge stainless steel construction requires minimum four to six undermount clips evenly distributed around the perimeter, with emphasis on the longer edges to prevent sagging under load. When installing in bar or island applications, verify faucet height clearance with the 8-inch bowl depth to ensure proper functionality. The sharp corner specification can be modified to include a small radius for easier cleaning if desired.
CNC Cutting Notes
CNC programming for the U109 rectangular template follows straightforward rectangular geometry with efficient toolpath execution. The template specifies 0.0 corner radius for sharp 90-degree angles, though fabricators commonly add a small 1/8-inch to 1/4-inch radius at corners for practical cleaning considerations and reduced stress concentration. Use a 3/8-inch or 1/2-inch diameter carbide bit for optimal cutting efficiency on straight runs. The 16x18 footprint allows for excellent material utilization when laying out multiple sinks or combining with other cutouts. Program your toolpath to start at the rear corner and proceed clockwise or counterclockwise around the perimeter, ending at the start point for clean closure. Set feed rates appropriate to your material—typically 100-150 IPM for quartz, 60-100 IPM for granite. The compact rectangular shape minimizes waste and cutting time while delivering professional results. Always simulate the complete toolpath before cutting to verify corner execution and overall dimensional accuracy.
Material Compatibility
The U109 stainless steel sink template integrates seamlessly with all countertop materials, offering particular advantages in contemporary and transitional kitchen designs. Granite fabricators appreciate the sink's professional construction and straightforward installation, with the brushed finish complementing both light and dark stone colors. In quartz installations, the precise manufacturing tolerances ensure consistent fit and professional appearance. The rectangular format works exceptionally well in galley kitchens, narrow islands, and peninsula applications where the orientation can be adjusted to suit available space. Marble countertop installations benefit from the stainless steel's resistance to etching, staining, and chemical damage that can affect natural stone. The undermount style creates clean transitions ideal for butcher block, solid surface, and laminate countertops. The commercial-grade 18-gauge construction ensures decades of reliable performance regardless of countertop material pairing.
