Kentech ST9-20M RJ11 4-Core Telephone Extension Cable (20 Meters)

• Extended Reach Line Extension: The Kentech ST9-20M is a high-length, commercial-grade telecommunications extension cable engineered to bridge substantial distances between a main telephone wall outlet and your communication equipment.
• Standard RJ11 Modular Interfaces: Outfitted with standard male RJ11 modular plugs (6P4C configuration) on both ends, serving as a straight-through patch cord for seamless hardware setups.
• Ultra-Long 20-Meter Profile: Provides a massive 20-meter (approximately 65.6 feet) length layout, giving you the necessary length to route lines across vast office spaces, between separate floors, or around expansive warehouse boundaries.
• Full 4-Core Ribbon Core Construction: Internally configured with a complete 4-conductor straight wire sequence, ensuring flawless signal handling for standard single-line home telephones, dual-line office arrays, or high-speed ADSL/DSL internet modems.
• Flat Anti-Tangle Outer Sheath: Protected by a highly flexible, flat PVC protective outer insulation jacket that minimizes the risk of complex cable knots and allows for discrete placement behind desks.

Features

• High-Flexibility Base Architecture: The flat ribbon structural design allows the cable to bend around tight trim corners, slide under carpets, or sit cleanly within plastic surface-mount wiring trunks without crimping the copper wire.
• Oxidation-Resistant Contact Pins: The internal copper-alloy interface contacts are coated in a high-conductivity plating that ensures clear analog voice transmissions and eliminates line crackle or signal dropouts over long runs.
• Snug Snap-In Retention Latch: Both male connector heads are molded with a resilient plastic locking clip that snaps firmly into phone sockets, preventing accidental signal disconnects caused by cable tugging.
• Durable Strain Relief Design: Built with integrated injection-molded strain relief support at both connector interfaces to safeguard internal copper strands from tearing loose during installation.
• Universal Telecom Compatibility: A versatile plug-and-play solution designed to function natively with landline telephone bases, fax machines, dial-up hardware, ADSL/DSL internet hardware, and credit card POS terminals.
