Explore our export-grade double-wall tandem systems, undermount concealed runners, 3D hydraulic hinges, and architectural pulls optimized for US standard cabinet dimensions.
Why custom cabinet fabricators in Mecklenburg, Union, and Iredell counties are transitioning from traditional dovetail wooden drawers to precision steel tandem box systems.
The Charlotte metropolitan area—stretching from the bustling urban core of Uptown Charlotte to suburban developments in Lake Norman, SouthPark, and Ballantyne—is experiencing an unprecedented real estate boom. Architectural woodwork manufacturers and multi-family cabinet contractors are facing urgent demand for sleek, space-efficient, and ultra-durable storage solutions.
Traditional wooden dovetail drawers require intensive manual labor, assembly time, and are vulnerable to dimensional shifting caused by North Carolina's humid subtropical summers. In contrast, double-walled steel tandem drawer systems offer 100% factory precision, zero seasonal warpage, integrated 3D alignment, and effortless soft-closing fluid action.
Architectural interior designers across the Carolinas are aggressively adopting European-style frameless cabinetry (Full Access Cabinetry). The modern Charlotte homebuyer favors flush exterior lines, ultra-slim metal drawer side walls (13mm profile), and deep pan drawers with integrated glass or gallery rails.
As a specialized OEM/ODM OEM Tandem Box Factory, Guangzhou Jarkul Hardware Co., Ltd. delivers standardized 32mm system drill patterns compatible with automatic CNC machinery used by North Carolina millwork plants, ensuring zero friction during high-volume production runs.
Comprehensive technical benchmarks engineered for B2B procurement officers, quality control engineers, and commercial cabinet buyers in North Carolina.

From initial CAD drawing confirmation to container loading at Guangzhou/Shenzhen ports, our dedicated account team ensures your product arrives exactly to spec.
Simplify your procurement supply chain by consolidating full cabinet hardware bills of materials into a single LCL/FCL ocean container:
Addressing essential technical, tariff, freight, and custom manufacturing inquiries for importers and distributors in North Carolina.
Production lead times for standard OEM tandem box orders typically range between 25 to 30 days following sample sign-off and deposit receipt. Freight is generally shipped via ocean container from Guangzhou (Nansha) or Shenzhen ports directly to East Coast US ports—primarily the Port of Charleston (SC) or Port of Wilmington (NC)—with an ocean transit time of roughly 28 to 34 days. From the port, containers are transported via rail ramp or direct flatbed trucking to Charlotte inland warehouses.
Our tandem steel drawer boxes are engineered specifically to prevent environmental oxidation and swelling common to humid subtropical climates. Drawer side walls and undermount runners undergo high-grade electrostatic epoxy powder coating or thick electro-galvanization, passing 48-hour to 72-hour Neutral Salt Spray (NSS) testing under ISO 9227 standards. Hydraulic dampening fluid within our soft-close cylinders maintains stable viscosity across ambient temperatures ranging from -15°C up to 50°C.
Yes. We provide complete OEM/ODM customized brand manufacturing for hardware distributors and cabinet manufacturers in North Carolina. Options include laser-engraved logo branding on steel side-wall cover caps, customized color retail boxes, barcoded master cartons tailored for automated distribution centers, and specialized inner polybag packing according to your exact product SKU guidelines.
For catalog-standard tandem box systems and concealed undermount slides, our baseline MOQ starts at 500 sets per model size. Standard OEM orders with custom logo covers or specialized powder-coat finishes require 1,000 sets. We support flexible international payment terms including T/T (Telegraphic Transfer), L/C at sight, D/P, D/A, and Western Union/PayPal for sample prototyping, with transactions accepted in USD, EUR, or CNY.
Absolute transparency is key to our customer relationships. Full SGS third-party laboratory test reports validating 50,000-cycle durability under DIN EN 15338 and 45kg static/dynamic load capacities can be provided. Furthermore, physical sample kits can be dispatched directly to your Charlotte facility via express courier (DHL/FedEx/UPS) so your engineering team can perform independent stress testing prior to placing commercial container orders.
