3U 19" Rack Shelf for Secure Component Mounting
The RC-3 is a 3U high, 19 inch wide rack shelf designed to hold audio, video or networking components in a standard equipment rack. Rubber-lined top clamps grip the unit securely while adjustable rear L-brackets stop it from sliding backwards during transport or vibration.
Clamping System and Ventilation Limits
The shelf uses rubber-lined clamps that secure components from above, which requires a flat top surface on the mounted device for proper grip. Vented sides and bottom provide passive airflow, but cooling performance depends entirely on the rack's overall ventilation and the component's own heat output.
70 lb Capacity with 17.4 x 15.1 Inch Usable Area
The 16-gauge steel construction supports up to 70 lb across a usable shelf area of 17.4 inches wide by 15.1 inches deep. Heavier chassis or deeper server units that exceed the depth or weight limit will need a different shelf solution.

Questions about this item
Which RC Series shelf should I choose for a 19-inch rack that needs 3U of height?
The RC-3 is built for a 19-inch rack width and occupies exactly 3U of rack height, giving a usable shelf area of 17.38 inches wide by 15.10 inches deep.
What does the 70 lb weight capacity mean once the shelf is installed in a rack?
It means the 16-gauge steel shelf can hold components weighing up to 70 lb, secured by rubber-lined clamps on top and adjustable rear L-brackets that stop gear from sliding backward.
How does the vented design affect airflow in a standard 19-inch rack?
Vented sides and bottom let cool air pass through the 17.4-inch wide by 15.1-inch deep shelf, helping dissipate heat from mounted equipment without blocking rack airflow.
