Four-Pack USB B to A Keystone Couplers

This four-piece set provides USB 2.0 Type B female to Type A female keystone couplers for panel-mount installations. The ABS housings with silver-plated pins deliver stable data transmission between connected cables. Each unit inserts directly into standard keystone cut-outs without soldering or tools. The black finish suits wall plates, patch panels, desktop grommets and rack enclosures.

Suits installers needing quick USB feed-through

These couplers suit technicians adding USB pass-through ports to existing keystone infrastructure for printers, scanners, hard drives or KVM switches. They are not for users who require a complete cable assembly with integrated wiring. Builders needing USB 3.x or USB-C pass-through should select a different coupler type. Anyone without a keystone panel or surface-mount box cannot mount these units.

USB 2.0 Type B female to Type A female

The decisive specification is the USB 2.0 Type B female to Type A female gender-change interface. This fixed pin-out determines which cables plug into each side and caps the signalling rate at USB 2.0 speeds. Verify that your host and peripheral both use the matching legacy connectors before purchasing.

Questions about this item

Should I buy the 4-pack or look for a single coupler?

The listing only offers a 4-piece set, so you receive four identical keystone couplers in one package.

What does USB 2.0 mean for transfer speed when I plug this into my PC?

The coupler passes the USB 2.0 signal through without active electronics, so the link runs at the standard USB 2.0 rate.

How does the keystone interface limit where I can mount it?

The snap-in keystone form factor fits standard keystone wall plates, patch panels and surface-mount boxes, but will not fit a plain round cut-out.
