Keystone blanking insert Alantec MKA-Z-B, white — keystone opening cover

Alantec MKA-Z-B is a white keystone blanking insert designed to fit standard keystone apertures in faceplates, wall plates and patch panels. The compact snap-in cover provides a discrete closure for unused keystone openings, creating a neat appearance and reducing dust ingress while preventing accidental contact with unused sockets. It is compatible with network, audio and AV installations that use standard keystone-compatible mounting systems.

Advantages

The slim snap-in design allows quick tool-free installation and secure retention in standard keystone slots. Its white finish matches common faceplate colours for a consistent look. The insert is non-conductive and provides a physical barrier to dust and debris in unused ports, helping maintain cable infrastructure cleanliness and reducing the risk of accidental connector damage.

Suitable for

• Covering unused keystone openings in wall plates and faceplates
• Closing spare ports on patch panels and distribution frames
• Audio-visual installations where temporary or permanent port blocking is required
• Network cabinets and structured cabling systems to improve appearance and safety

Key specifications

• Colour: white
• Form factor: standard keystone snap-in blanking insert
• Material: durable non-conductive plastic
• Mounting: snap-in retention for standard keystone apertures
• Application: suitable for faceplates, wall plates, patch panels and keystone-compatible modules

How to use

To install, align the insert with the keystone opening and press it into the aperture until it snaps into place. Ensure the retaining tabs engage to secure the cover. To remove, gently depress the retention tabs from behind the plate or from the exposed edges and pull the insert out. The insert can be installed before or after mounting the plate or panel depending on access and installation sequence.

Usage recommendations

Use one blanking insert per unused keystone port to maintain a tidy appearance and reduce dust accumulation. For installations in higher-dust environments, periodically remove and clean both the insert and the surrounding aperture to prevent dust build-up. Match the insert colour to your faceplate for the most discreet finish.
