The listings include very short couplers under a foot and longer extension cords. Example lengths shown are about 0.59 ft, 1.5 ft, 5.1 ft, 7 ft, and 33 ft.
Connectors and cords are offered as Male‑to‑Male, Male‑to‑Female, and Female‑to‑Female. Some small modular plugs are listed without a specified connection gender.
Common construction includes plastic housings and PVC insulation with copper conductors. Several items list gold‑plated contacts and clear plastic housings with metal pins.
The connectors and cables are described for use with landline telephones, fax machines, modems, and answering machines, suitable for home and office phone and data lines.
Listings reference six conductors for some cables, a 6‑position/4‑contact (6P4C) RJ11 configuration, and at least one cable specified as 28 AWG.
Flat cables help reduce kinking and clutter for neater routing, while stranded conductors offer greater flexibility and are generally easier to install than solid core options.
Items are sold as single pieces, small multi‑packs (for example 2‑piece or 2‑pack), and larger packs such as a 20‑pack.
Compact splitters and couplers are shown with small footprints. Example dimensions include 33 x 27 x 21 mm (about 1.3" x 1.1" x 0.83"), 1.5" x 0.8" x 0.9", and 3.1" x 1" x 1".
