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.

Perfect for ball demolishers
Size: Medium
The dogs love the chuck it brand. I don’t know what it’s made of but they go crazy over them. Will not play with another ball. Wonder if it’s “laced” with an addictive scent. Have pits. Very durable. Not able to chew to pieces. Last for about 6 months before there is a small break. I keep a back up because when the ball goes missing the house is in chaos. 😆 🤪

Chuckit medium rebound balls
Size: Medium
My 8 month old German shepherd dog loves these balls. They are easy to throw, they bounce great, they are very chewable! She keeps one in her mouth most of the time. It satisfies her need to chew and she does not chew other things. She drops it in the water and lets the hole fill up and drinks that way. The only problem that has caused is suction in her mouth and difficulty in dislodging it for her. However, she would be lost without it!

These are definitely indestructible
Size: Medium
Both of my dogs can destroy a ball in a matter of minutes if I let them play with them (supervised) as is. Well not with these balls. They are the ONLY ones I have found that are 100% indestructible. Please only let your dogs play with these as a toy when supervised though. They go really far when throwing them, so both dogs get a good amount of running and exercise with these. I also bought these because they have the hole in the middle of the ball which is very important in the event that a dog gets one stuck at the back of their throat. This allows them to breath unlike those without this hold. It's an unlikely event, but as dog owners, we all need to be aware of this and educate ourselves on what to do if this SHOULD happen. This isn't a scare tactic, nor a reflection of this particular brand, it can happen with any type of ball. My two dogs are about 45ish lbs and the size is perfect for them, I don't want anything smaller than this. They love them. There is no annoying squeak. Really easy to wash after use. Some balls take forever to get the slimy saliva off, but these don't.
