Installation Overview
The Alpha International AS2114 undermount installation follows standard practices adapted to this model's specific 20.5" x 14.37" footprint. The sink's 1" rim (calculated from 20.5" outside to 18.5" bowl dimension) provides adequate surface for mounting clip attachment and adhesive bonding across all material types. This template package includes four proven cutout variants: the no-reveal configuration (18.5" x 12.37") cuts flush to the bowl edge, maximizing the visible sink opening and creating seamless stone-to-sink transitions favored in contemporary design. This option leaves minimal stone overlap for clip installation, making adhesive bonding a critical component of the mounting system. The 1/8" reveal variant (18.25" x 12.12") represents the industry-standard specification, creating a subtle shadow line while providing tolerance for sink positioning variation during installation—this is the most commonly requested configuration across residential projects. The 1/2" overhang option (17.5" x 11.37") delivers substantial stone coverage onto the sink rim, maximizing contact area for both mechanical clips and adhesive systems—ideal for commercial installations, heavy gauge sinks, or situations where undermount reliability is paramount. The drop-in variant (20.5" x 14.37") matches the sink's outer perimeter and accommodates alternative top-mount installation if project parameters change during fabrication. The AS2114 fits 27" minimum cabinet width, though 30" bases provide better clearance for plumbing, garbage disposal units, and under-sink storage. The 7.5" bowl depth offers functional workspace while maintaining adequate clearance beneath standard 3cm countertop materials. The rectangular zero-radius corner geometry requires specific CNC tooling approaches but produces the sharp, precise lines that define contemporary kitchen aesthetics.
CNC Cutting Notes
CNC programming for the AS2114 cutout focuses on managing zero-radius corner geometry across various materials. Unlike radiused sinks allowing continuous tool paths, rectangular designs require strategic corner management—the end mill must either plunge at 90-degree corners or utilize specialized corner-cutting sequences. For natural stone materials (granite, marble, soapstone), specify 1/4" to 3/8" diameter end mills that balance corner proximity with reasonable tool strength and cutting speed. Program tool paths with proper corner compensation using circular interpolation at the minimum radius your tooling allows—typically 0.125" to 0.1875" radius at corners for these tool sizes. In quartz and porcelain slabs, sharp corners present elevated chip-out risk during both roughing and finishing passes. Reduce feed rates by 30-40% when approaching corners and consider leaving additional stock (0.030-0.040") for hand-finishing with angle grinders equipped with diamond hand pads. The AS2114's cutout area (approximately 230 square inches for the no-reveal variant) generates manageable waste material easily supported with standard vacuum pod arrays or mechanical clamp systems positioned outside the cut perimeter. Ensure waste piece stability through final breakthrough to prevent vibration that could compromise edge quality. For the 1/8" and 1/2" reveal variants, reduced cutout dimensions provide progressively more rim area for undermount clip installation—verify clip positioning doesn't interfere with bowl walls, particularly at corners where clearance is tightest. The sink's 7.5" vertical depth accommodates most standard undermount clip systems even with 3cm stone, though clips with 2" or greater vertical reach are preferred. When programming finish passes, leave 0.020-0.025" stock on all exposed edges for hand-polishing to final dimension and edge treatment. Carbide tooling life will be reduced at corners where repeated plunge cuts accelerate wear—monitor tool condition and replace before degradation affects edge quality. Some fabrication shops prefer to rough-cut rectangular openings with 1/4" or 1/2" corner radii, then use corner-cutting jigs or specialized hand techniques to achieve final zero-radius geometry—this hybrid approach can deliver superior edge finish in brittle materials while optimizing CNC efficiency.
Material Compatibility
The AS2114 template supports professional fabrication across all contemporary countertop materials, with the rectangular zero-radius design presenting material-specific advantages and challenges. Quartz surfaces (Cambria, Caesarstone, Silestone, Q Premium Natural Quartz) handle this cutout configuration well when proper tooling and techniques are employed. The sharp corners demand attention to prevent microchipping—use freshly sharpened diamond tooling, conservative feed rates approaching corners, and plan for hand-finishing to achieve refined edge quality. The AS2114's moderate size relative to standard slab dimensions provides adequate surrounding material for structural integrity even in 2cm thickness, though 3cm delivers superior visual mass and structural performance. Natural granite excels with rectangular zero-radius cutouts, as granite's interlocking crystalline structure tolerates stress concentration at sharp corners better than resin-based engineered materials. Position high-contrast veining and existing fissures away from corners where they could compromise structural integrity. Marble applications require more conservative land area calculations (3" minimum from cutout edge to slab perimeter) given marble's lower tensile strength compared to granite—the AS2114's compact footprint works well in marble installations where larger sinks might exceed material structural capabilities. Solid surface materials (Corian, Hi-Macs, Staron, LG Viatera) represent ideal applications for this template, machining easily with carbide or diamond tooling to produce perfect zero-radius corners without chipping concerns. The rectangular geometry also simplifies seam placement when required near sink areas—perpendicular seams can intersect corner regions with proper joint design. Porcelain slabs demand continuous water cooling and premium diamond tooling throughout the cutting cycle, with sharp corners requiring careful tool path programming to prevent deflection-induced edge fracture. Ultra-compact surfaces (Dekton, Neolith, Lapitec) deliver excellent structural performance with zero-radius geometry but accelerate tool wear, particularly at corners—calculate tooling costs when bidding projects using these materials. The AS2114's 1" rim width provides adequate support for standard undermount clip systems across all material types and thicknesses, though 3cm and thicker materials benefit from clips with extended vertical engagement.
Where to Buy
The Alpha International AS2114 is available through professional plumbing distributors, fabrication material suppliers, kitchen and bath showrooms, and direct from Alpha International's dealer network. As a value-focused product line, Alpha International offers competitive pricing that appeals to production builders, remodelers, and cost-conscious residential projects while maintaining construction quality suitable for professional installation. The AS2114 typically retails between $180-350 depending on gauge specification (18 or 16), finish treatment, and order volume. Professional fabricators should establish accounts with Alpha International authorized distributors to access contractor pricing, typically 30-40% below retail on volume orders. Online purchasing options include Amazon (Alpha International's official storefront featuring customer reviews and Prime shipping), specialized plumbing e-commerce platforms, and kitchen fixture retailers offering competitive pricing with direct job site delivery. The manufacturer's website (alpha-int.com) provides a valuable DXF file library where fabricators can download CAD drawings for the AS2114 and verify dimensions before physical sink arrival—this resource streamlines template preparation and CNC programming while reducing risk of dimensional errors. Lead times for Alpha International products typically run 3-10 days for in-stock configurations, substantially faster than premium brands that may require 3-6 weeks for special orders—this rapid availability benefits fabricators managing tight project schedules. When ordering, confirm the specific model designation to ensure correct depth specification (AS2114 standard vs. potential ADA shallow-depth variants). Some distributors offer undermount installation kits bundled with sink purchases, including mounting clips, professional-grade silicone adhesive, and support hardware as complete packages—these kits streamline procurement and ensure compatible components. For commercial projects specifying multiple AS2114 units, contact Alpha International directly regarding volume pricing, custom gauge options, or specialized finish requirements beyond standard offerings.
