NEMA 1-15P to Multi-Outlet NEMA 1-15R Indoor Extension Cord
Flat SPT Cable Profile: Built with a flat parallel 2-conductor jacket (SPT-1 or SPT-2) that routes easily under rugs, behind desks, and flush against baseboards. This keeps indoor installation spaces clean and prevents tripping hazards.
Integrated Hanging Loop: The receptacle block is designed with a molded hanging ring at the tip. Installers can secure the outlet block to walls, display racks, or temporary holiday lighting setups to keep the connection off the floor.
NEMA 1-15 Non-Grounding Interface: Utilizes a standard US 2-prong NEMA 1-15P plug matched to NEMA 1-15R outlets. This configuration is specifically engineered for 125V AC double-insulated indoor equipment that does not require a protective earth connection.
OEM Customization Ready: Total cord length, wire gauge (18AWG/16AWG), jacket color, exact outlet count, packaging design, and certification route can be customized to match your retail or commercial procurement specifications.
- Product Description
NEMA 1-15P to Multi-Outlet NEMA 1-15R Indoor Extension Cord with Hanging Loop
The NEMA 1-15P to Multi-Outlet NEMA 1-15R Indoor Extension Cord solves everyday indoor power shortages. It converts one standard US 2-prong wall outlet into multiple connection points for double-insulated electronics. Designed with a flat SPT jacket for low-profile routing and an integrated hanging loop for secure mounting, this assembly delivers highly practical power distribution. Built to strict factory standards. Delivered with a verified 0.1% defect rate for bulk commercial procurement.



Why Choose Our Multi-Outlet Indoor Extension Cord?
Standard single-outlet extension cords often leave users frustrated when multiple small devices need power in the same area. This multi-outlet design expands capacity while keeping the cable profile thin and manageable.
Multi-Outlet Block Expands Power Access
The molded female receptacle block features multiple NEMA 1-15R slots (typically 2 or 3 outlets depending on configuration). This structural expansion allows users to plug in a lamp, a phone charger, and a clock simultaneously from a single wall socket.
For retail buyers and commercial offices, this reduces the need for bulky, expensive power strips when only low-current 2-prong devices are being used.
Flat SPT Jacket for Low-Profile Indoor Routing
Instead of a thick round cable, this cord utilizes an SPT-1 or SPT-2 flat parallel wire jacket. The conductors sit side-by-side, creating a thin profile that easily slides under area rugs, squeezes behind heavy bookcases, or runs flush along baseboards.
This design prevents tripping hazards and eliminates the ugly enclosure bulges caused by pushing furniture against thick round cables.
Molded Hanging Loop for Secure Mounting
The end of the receptacle block incorporates a solid molded hanging ring. Installers can easily slip this loop over a nail, hook, or zip tie.
When setting up display racks, workstation power, or temporary holiday lighting, this feature keeps the connection points elevated off the floor, reducing the risk of water exposure or accidental kicking.
2-Prong Non-Grounding Compatibility
The NEMA 1-15P to 1-15R configuration is strictly 2-prong. This targets the massive market of double-insulated consumer electronics that do not require an earth ground, saving material costs over 3-prong cables while perfectly matching the connected equipment's safety design.

Buyer's Insight: The most common misuse of a multi-outlet cord is overloading. A 3-outlet block does not triple the power capacity; the total combined current of all plugged-in devices must remain below the cable's maximum rating (e.g., 13A for a specific 16AWG build). Always specify the correct wire gauge based on the target retail market's expected usage habits.
Professional Applications You Can Trust
For household and office environments, wall outlets are often hidden behind heavy desks or sofas. This flat extension cord brings power out into the open, providing three accessible slots for phone chargers, desk lamps, and small fans without moving furniture.
For retail display and exhibition booths, lighting needs to be distributed cleanly. The integrated hanging loop allows technicians to secure the receptacle block directly to the display framework, keeping power off the ground and neatly organized.
For seasonal and holiday lighting, users often string multiple low-wattage light sets together. This 2-prong splitter safely distributes 125V AC to multiple light strings from a single indoor source.
Advanced Safety Features
This is a non-grounding extension cord strictly designed for indoor use. It must only be used with 2-prong, double-insulated devices. Do not attempt to plug a 3-prong grounded device into this receptacle block.
The SPT PVC jacket is intended for light to medium indoor duty. It is not rated for outdoor weather exposure, extreme cold, or harsh industrial abrasion.
Both the male plug and female block feature injection-molded strain relief to protect the internal copper wires from fracturing under repeated plugging, unplugging, and bending.
Manufacturing Excellence
With over 17 years of cable manufacturing expertise, our factory produces high-volume retail and OEM extension cords. Every batch undergoes 100% automated electrical testing, including polarity, continuity, and Hi-Pot dielectric checks. We use strictly compliant virgin PVC and pure copper to ensure safety and longevity.
Frequently Asked Questions
Q: Can I plug a 3-prong device into this cord if I use an adapter?
A: No. Using a 3-prong to 2-prong adapter on an extension cord defeats the equipment's earth ground safety feature. This cord is strictly for 2-prong devices.
Q: Can the color of the cord be customized?
A: Yes. While black and white are standard, we can manufacture the PVC jacket and molded connectors in custom colors (like brown, green, or transparent) to match retail packaging or specific interior decors.
Q: How long does a custom sample take to produce?
A: For standard gauge and color combinations, our sample dispatch timeline is typically 3-5 working days after drawing approval.
Q: What information is needed for a quotation?
A: Please provide the total cable length, exact number of required outlets on the block, wire gauge (18AWG/16AWG), jacket color, target certification, order quantity, and packaging requirements (e.g., retail sleeve, polybag, or bulk tie).
Custom Solutions for Your Business
Length Customization: Define exact lengths (e.g., 6ft, 9ft, 12ft, 15ft) to target different retail segments, from short desktop extensions to long room-spanning cords.
Wire Gauge & Material: Choose 18AWG for standard low-power lamps and chargers, or upgrade to 16AWG for longer runs that support slightly heavier indoor loads.
Color & Branding: Select custom jacket colors to blend with flooring or walls. Add custom cable printing, molded logos on the plug, and retail-ready packaging like printed sleeves or header cards.
Certification Matching: We provide cords manufactured and documented to pass strict compliance checklists for the North American market.
