Curly Cords

UL-listed curly cords for telephone handsets, healthcare equipment, dispatch radios, control panels, and test leads. Retractile by design, manufactured in North Branford, CT since 1947.

What Are Curly Cords Used For?

Curly cords — also known as retractile or coiled cords — keep workspaces organized while providing the reach you need. Autac curly cords are built for reliability in demanding communications, control, and testing environments.

Why Are Phone Cords Curly?

The curly handset cord is one of the most familiar coiled-cable applications in the world — and the engineering reason behind it is the same reason curly cords are used across industrial, medical, and dispatch environments today. A handset has to reach the user's ear from a base station and return to a compact resting state when not in use. A straight cord either has to be too short to be useful or constantly tangled across the desk. The helical coil solves both problems simultaneously: it extends to several times its retracted length under tension and pulls itself back into place when released.

Curly cords are manufactured by winding straight insulated cable around a heated mandrel, then heat-curing the jacket compound at controlled temperature and time. The cure permanently sets the helix into the molecular structure of the jacket — not as a temporary deformation but as the cable's new resting shape. The same heat-set process Autac has refined since 1947 produces every Autac curly cord, from a 26 AWG telephone handset cord to a multi-conductor dispatch radio cable.

Curly Cord vs. Coiled Cord vs. Retractile Cord: The Same Product

The terminology gets confusing because every industry uses different words for the same product family.

Whichever term you searched for, you are looking at the same underlying product. Autac builds them all under the same UL-listed manufacturing process at our North Branford facility.

Where Curly Cords Are Used Today

Despite the rise of mobile devices, curly handset cords and other curly-cord applications remain critical infrastructure across half a dozen industries. Reliability, signal integrity, and the ability to disinfect or service a fixed cord matter more than mobility in these environments.

Healthcare & Hospitals

Patient room phones, nurse stations, and medical-cart handsets. Antimicrobial PVC jackets meet healthcare cleaning protocols.

Hospitality

Hotel guest-room phones, bell desks, and front-desk operations. Long service life and a familiar user experience for guests of any age.

Call Centers & Operations

Multi-line phone systems, headset cables, and dispatch consoles where 24/7 reliability is non-negotiable.

Emergency Dispatch

911 dispatch handsets, public safety radios, and fire/police/EMS communications. Shielded options block radio interference.

Industrial Control Panels

Pendant controls, hand-held programming terminals, and machine operator stations on the factory floor.

Test & Measurement

Auta-Prene test leads for utility meters, multimeters, and field instruments. Flexes reliably in cold and oily environments.

Government & Federal

Secure facility phones, tactical communications, and federal procurement contracts. WBENC-certified woman-owned supplier.

OEM Custom Builds

Built-to-spec curly cords with custom terminations, jacket colors, and conductor counts for medical, AV, and specialty equipment.

Curly Cord Questions
A curly cord is an electrical or signal cable wound into a helical spring shape that extends under tension and retracts to its compact resting length when released. The helix is permanently heat-set into the cable's jacket compound during manufacturing. Curly cord, coiled cord, retractile cord, and coil cord are all the same product family — "curly cord" is the consumer-facing term most often associated with telephone handset cords.
Phone cords are curly so the handset can be picked up, moved across a desk, and held to the ear without dragging a long straight cable across the work surface. The curly geometry retracts when not in use, keeping the cord out of the way, and extends to several times its retracted length when needed. Without the coil, a phone cord would either be too short to use comfortably or constantly tangled.
Hospitals, call centers, hotels, emergency dispatch centers, manufacturing plants, and government facilities all still rely on curly handset cords because landline phones remain critical infrastructure where reliability matters more than mobility. Beyond phones, curly cords are used for dispatch radio handsets, headset cables, hand-held controllers and pendants on industrial equipment, test leads on utility meters and multimeters, and medical instrumentation.
Curly cord tangles come from the cord being twisted axially over time as the handset is rotated relative to the base. Each rotation adds a fraction of a turn to the cord's underlying twist, and these accumulate until the helix kinks back on itself. The fix is simple: unplug one end, let the cord hang freely, and let it spin out the accumulated twist. A higher-quality cord with a properly cured jacket compound (like Autac's Auta-Prene) holds its coil memory better and resists permanent kinking from years of normal handset rotation.
There is no engineering difference. Curly cord, coiled cord, retractile cord, and coil cord all describe the same product. The terminology reflects how different industries refer to it: "curly cord" is consumer language (especially for phones), "coiled cord" is engineering language, "retractile cord" is UL product-category language, and "coil cord" is purchasing language. Autac builds them all under the same UL-listed manufacturing process.
Yes. Autac builds custom curly cords to specification with no minimum order quantity — common for OEMs sourcing handset cords for medical devices, hospitality phones, dispatch radios, and specialty equipment. You specify conductor count, gauge, voltage rating, retracted length, extension ratio, jacket compound and color, optional shielding, and termination connectors. Quote turnaround is typically one to three business days. Start at Build Your Cord.
PVC is the most common choice for indoor curly cords like phone handsets, control panels, and consumer electronics — cost-effective, flame retardant, and available in standard colors. For curly cords used in environments with chemical exposure, temperature extremes, or heavy mechanical wear (test leads, dispatch handsets, factory pendants), Auta-Prene — Autac's proprietary thermoset rubber compound — delivers superior coil memory, abrasion resistance, and a wide service temperature range.
Standard Autac curly cords use a 1:5 extension ratio: a cord with a 12-inch retracted length extends to 60 inches under tension. Custom ratios from 1:3 (more aggressive retraction, longer resting length) to 1:7 (more reach, gentler retractive force) are available depending on application. Cycle life on a properly specified curly cord exceeds 100,000 extensions in normal service.
