Blank Keystone Inserts for Wall Plates

These black snap-in blanks fill unused keystone ports in patch panels and wall plates. They maintain a clean, professional appearance in structured wiring installations. The UL Listed components come in a pack of ten for multiple openings.

Replaces Exposed Port Openings

Use these inserts when terminating cables leaves empty keystone slots that collect dust or look unfinished. The jump is worth it whenever a port is decommissioned or reserved for future expansion. They snap in without tools and stay secure in standard keystone cutouts.

Ten-Pack Coverage for Standard Cutouts

Each blank occupies one keystone aperture and the ten-piece quantity covers a typical patch panel row or several wall plates. They add no connectivity and pass no signal, so capacity is limited to physical port closure. The plastic construction suits indoor, low-voltage environments.

Questions about this item

Will the SFBB10 blank keystone insert snap into a standard keystone wall plate or patch panel?

Yes, the SFBB10 is a snap-in keystone blank designed to fit standard keystone openings in wall plates, surface-mount boxes and patch panels.

Does installing the SFBB10 require any tools or termination steps?

No tools or termination are needed; the blank insert simply presses into the keystone opening until the retention clips latch, and the common mistake is not pushing firmly enough to engage both clips.

Will the black plastic of the SFBB10 fade or become brittle over time in a typical indoor installation?

The UL-listed black plastic is rated for normal indoor use and does not require replacement unless the insert is physically damaged or removed during a remodel.
