The Black Box Ethernet Extender - 4-Port is a high-performance solution designed to bring Ethernet connectivity to distant locations over existing copper wiring. Built on ITU-T G.991.2 SHDSL.bis symmetric technology, this extender delivers rate-adaptive nx64 speeds up to 15 Mbps, providing dependable, balanced uplink and downlink performance over two-wire copper. Ideal for linking remote offices, manufacturing floors, security camera networks, and industrial environments, this device enables you to extend your LAN without the expense and disruption of running new fiber or coax. With a pair of units communicating over copper cables rated from 19 AWG to 26 AWG, you gain a flexible, scalable network extension that supports modern business demands while preserving your current cabling investments. The 4-Port variant adds considerable versatility by offering multiple Ethernet connections on each NTU, allowing you to consolidate devices, reduce wiring complexity, and streamline deployment in compact spaces. Whether you are modernizing an existing copper network or deploying a new, cost-effective extension, this Ethernet Extender delivers stable, scalable performance with minimal configuration.

  • High-speed Ethernet over copper: Leveraging ITU-T G.991.2 SHDSL.bis, the device provides rate-adaptive nx64 speeds up to 15 Mbps symmetric, ensuring balanced performance for file transfers, video streams, and real-time applications across the extended link.
  • 4-port Ethernet interface on each unit: Four LAN ports on the NTU deliver flexible connectivity for multiple devices, allowing a small office, workshop, or remote site to share a single SHDSL link without sacrificing individual device performance.
  • Flexible copper compatibility: Designed to operate over dry two-wire copper cables across a range of gauges from 19 AWG (0.9 mm) to 26 AWG (0.4 mm), providing install versatility and compatibility with legacy and current cabling environments.
  • Easy pair-and-connect deployment: The extender is engineered to work in matched pairs, creating a transparent Ethernet bridge between sites with straightforward wiring and minimal setup, so you can deploy quickly and reliably.
  • Rugged, business-class reliability: Built for commercial environments, the Black Box Ethernet Extender emphasizes robust construction and dependable performance to support continuous operations in office, industrial, or campus settings.

Thick, soft, perfect for my service dog to lay on in restaurants, etc.
Color: Blue, Style: 1/2 Inch
I bought this for my service dog to lay on in restaurants, etc. It's super thick and soft. I cut it in half and I'm using the other half for my dog to lay on in the car. Excellent quality and I love the carry strap.

Comfortable and thick mat that’s great for workouts at home
Color: Black, Style: 1/2 Inch, Color: Black, Style: 1/2 Inch
I picked up this Amazon Basics extra thick exercise mat for home workouts, and it’s been a solid addition. The thickness is the first thing you notice—it provides good cushioning, especially for exercises where you’re on your knees, elbows, or back. The surface has enough grip to keep you from slipping during most movements, whether you're doing stretching, core work, or basic workouts. It also stays in place pretty well on the floor without sliding around too much. The mat rolls out flat easily and comes with a strap, which makes it convenient to store or carry if needed. It’s lightweight enough to move around but still feels durable. It’s not a high-end studio mat, but for everyday workouts at home, it does exactly what you need it to do. Pros: • Extra thickness provides good cushioning • Comfortable for floor exercises • Lightweight and easy to store • Good value for the price Cons: • Slight compression over time with heavy use • Grip is good but not premium-level Overall, this is a great budget-friendly mat for home workouts, stretching, or basic fitness routines.

Maximum joint comfort and durability
Color: Pink, Style: 1/2 Inch
I absolutely loved the color, and it offers incredible cushioning without sacrificing stability during balance poses. It is dense, doesn't lose its shape, and springs back instantly. The materials are high-quality, and it doesn't have that strong plastic smell that others often have. It is worth every penny for the comfort it provides.

PLUSH! Fabulous yoga mat!
Color: Black, Style: 1/2 Inch
SO comfortable! It feels like a soft memory foam padding. I use it for several exercise classes and it is great for all of my needs! I love the strap it comes with to keep it rolled up in between classes and the ability to carry it anywhere.
