3 Space Rack Clamp for Component Captivation

The Middle Atlantic RC-3 is a 5.5 in. clamping rack shelf designed to secure components that require captivation. It suits installers and integrators who need an economical way to hold equipment firmly in a standard rack. Rubber-lined clamps grip the component from the top while adjustable L-brackets at the rear provide an optimally secure fit. The unit is built from 16-gauge steel for structural integrity.

Check Rack Space and Component Height Before

Verify that your rack has three consecutive rack spaces available for this clamp shelf. Confirm the overall height of the component you intend to mount does not exceed the usable space within the 5.5 in. depth. Ensure the component's top surface is suitable for the rubber-lined clamps to grip effectively. The adjustable rear L-brackets must align with your rack's rear mounting rails for a secure installation.

Vented Bottom Aids Cooling in Normal Use

A vented bottom panel allows airflow to pass through the shelf, helping to dissipate heat from the mounted component during operation. The 16-gauge steel construction maintains rigidity without adding unnecessary mass. No fans or active cooling are included, so thermal performance depends on the rack's overall airflow design. Noise is limited to any vibration transmitted through the clamps and brackets.

Questions about this item

Does the RC-3 ship with the rubber-lined clamps and adjustable L-brackets, or must they be ordered separately?

The clamp ships complete with rubber-lined top clamps and adjustable L-brackets at the rear; no additional hardware is required for basic mounting.

Should I choose the 3-space 5.5 in. RC-3 or a different Middle Atlantic clamp for a deeper component?

The RC-3 provides 5.5 in. depth across 3 rack spaces; select a deeper CAP series model only if your component exceeds that depth.

How does the 16-gauge steel construction affect the load the RC-3 can carry in a mobile rack?

The 16-gauge steel frame maintains structural integrity on the road, keeping clamped components secure under vibration and shock.
