Overview

The Monoprice 105377 Cat5E Punch Down Keystone Jack offers a simple, cost-effective way to create permanent network connection points throughout a home or office. Using the industry-standard 110-type IDC termination, this jack accepts solid-core Cat5E cable and provides a clean RJ45 port that snaps into any compatible keystone wall plate or patch panel. The 90-degree connection design routes cables perpendicular to the faceplate, making installation in shallow wall boxes more manageable.

The bright yellow housing serves as a useful visual identifier when running multiple network lines to different rooms or zones. However, prospective buyers should note one important limitation: the jack's body is wider than some competing designs, which means you cannot mount two of these side by side in a standard two-port keystone wall plate. If you need multiple ports in a single plate, you may need to verify fitment or consider alternative configurations. For single-port installations or patch panel use, this jack delivers reliable Cat5E performance at a fraction of the cost of name-brand alternatives.
