Port dust cover DELOCK 86403, set of 4, black, 17.3×22.3×16.3 mm

DELOCK 86403 is a set of four black port dust covers designed to protect unused ports and openings from dust, dirt and debris. Each cover measures 17.3 mm (width) × 22.3 mm (depth) × 16.3 mm (height) and is intended for snap-in mounting in standard keystone-style openings such as patch panels, faceplates or surface-mount boxes. The compact design helps maintain cleanliness of connectors and panel openings when ports are not in use.

Advantages

These port dust covers provide a simple mechanical barrier that prevents particles and contaminants from entering unused ports. Their standardised keystone-compatible shape allows for easy snap-in installation and secure retention without additional tools. Supplied as a set of four, the covers are lightweight and compact, suitable for use in confined spaces and multiple installation points.

Suitable for

• Keystone patch panels and rack-mounted panels
• Faceplates and wall plates with keystone cutouts
• Surface-mount boxes and small enclosures
• Protecting unused data, audio or custom connector openings

Key specifications

• Colour: black
• Quantity: set of 4 covers
• Dimensions (W × D × H): 17.3 × 22.3 × 16.3 mm
• Mounting type: snap-in keystone-compatible
• Application: port and panel protection from dust and debris

How to use

Align a dust cover with the keystone-style opening and press gently until it snaps into place. To remove, use a flat tool or a fingernail to depress the retention tabs and pull the cover out of the opening. Use these covers on unused ports to keep connectors and internal contacts free from contamination and to maintain reliable connector performance when ports are later populated.

Recommendations

Install covers in all unused keystone openings during assembly and maintenance to reduce airborne contamination. Inspect covers periodically for damage or wear and replace if they no longer retain securely or if they become cracked.
