Black Box CAT5e Unshielded Straight Pinned Coupler (Off White)

The Black Box FM507-R2 is a CAT5e coupler that lets you join two Ethernet patch cables and extend a network run without installing new cable.

A straight-through pin layout keeps the wiring pattern intact from one side to the other. The coupler supports both T568A and T568B standards, so it integrates smoothly with existing installations. Each end has an RJ-45 eight-wire female jack, providing the same connection you find on common patch panels and wall outlets.

Installers can tuck the coupler behind a desk, inside a rack, or above a ceiling tile when a cable is a few inches short. IT staff often keep several in a toolkit for quick repairs or temporary links during troubleshooting. At home, anyone who moves furniture and discovers the network cable no longer reaches the router will appreciate the same convenience.

The off white housing blends into office walls and equipment enclosures, and its small size fits easily in tight spaces without adding bulk to a cable bundle.

In short, the FM507-R2 provides a dependable way to maintain network continuity while staying within CAT5e performance limits.
