StarTech.com Steel Low Profile Expansion Slot Cover Plate - 5 Pack

The StarTech.com Steel Low Profile Expansion Slot Cover Plate - 5 Pack is an essential computer component accessory designed for desktop computer cases to cover unused half-height expansion slots. Built from durable steel, these blanking plates help maintain proper internal airflow by preventing air leaks, reduce dust and debris buildup inside the desktop system, and provide a clean, finished appearance to the back of the computer chassis. This 5-pack offers a practical solution for IT professionals, system builders, and hardware enthusiasts working on computer maintenance, custom PC building, and hardware upgrades.

Advantages

Using these steel low profile expansion slot cover plates ensures that your computer chassis maintains an optimized thermal environment by directing airflow correctly through active cooling components rather than open gaps. The sturdy metal construction provides long-lasting durability and reliable protection against physical damage to the interior of the system. Additionally, closing open gaps significantly minimizes dust accumulation on internal components, which helps extend the lifespan of your hardware and reduces the frequency of required maintenance cleanings. The clean finish enhances the overall aesthetic of the computer back panel.

Suitable for

• Covering unused half-height PCI and PCIe slots on desktop computer cases
• Maintaining proper internal airflow and cooling efficiency
• Reducing dust and particle buildup inside computer systems
• IT maintenance, system repair, and custom PC building
• Completing hardware upgrades and replacing lost or damaged slot covers

When it may not be suitable

This product is not suitable for computer cases that require standard full-height expansion slot covers, as these plates are specifically sized for low profile systems. They cannot be used in slots currently occupied by active expansion cards or ports that require physical clearance.

Key specifications

• Design: Low profile / half-height expansion slot cover
• Material: Durable steel
• Quantity: 5 plates per pack
• Item weight: 7 g
• Dimensions: 18 mm width, 75 mm depth, 120 mm length

How to use

To install the slot cover, first ensure your computer system is powered off and unplugged from the electrical outlet for safety. Remove the side panel of your computer case to access the rear expansion slots if necessary, though installation can typically be performed directly from the exterior. Align the metal low profile cover plate with the empty expansion slot opening on the back of the chassis. Secure the plate using the existing screw from your computer case, tightening it firmly to prevent vibration or movement. Repeat the process for any additional unused slots you wish to cover.

What to consider before purchase

• Verify that your computer case and motherboard support low profile or half-height expansion cards
• Check the number of empty slots you need to cover to ensure the 5-pack quantity meets your requirements
• Confirm whether your chassis utilizes screw-in retention or toolless mechanisms for slot covers

Always ensure the computer is turned off and disconnected from power before opening the chassis or installing internal and external components. Keep small screws and metal parts away from children and pets during installation.
