Black Box cable coupler

With Category 5e Modular Jacks, you get full-featured end-to-end connectivity. A patented "gravity feed" jack controls the bend radius of the mating modular cords. This ensures the integrity of the transmission channel by physically protecting the plug/jack connection from contact with office furniture. An angled shroud creates a slim profile for installations in tight spaces. And "pair balance" technology gives you consistent high-transmission performance and product reliability.

The Double Couplers have two modular RJ-45 jacks connected to a 4-pair S110 connecting block.
