1U Cable Management Arm for 19″ Racks

The 1UCMA-137 is a steel cable management arm built for 19-inch server racks. It occupies a single rack unit and is designed specifically for equipment mounted on slide rails. System administrators and data-centre technicians use it to keep cabling tidy while hardware remains fully serviceable.

Adjustable Extension Handles Sustained Movement

The arm extends from 28.5 inches to 33 inches (724 mm to 838 mm), allowing cables to follow the equipment as it slides in and out without binding. Its compact steel construction resists fatigue during repeated cycles, and the reduced profile compared to OEM arms leaves more usable space inside the rack.

Verify Rack Hole Type

Confirm that your rack uses either square or round mounting holes, as the arm supports both. Ensure the slide rails on your equipment provide enough travel for the 28.5-to-33-inch range and that the chosen left or right mounting side does not interfere with adjacent devices or rack doors.

Questions about this item

Does the steel construction of the 1UCMA-137 generate noticeable heat or noise during continuous operation?

The arm is a passive steel cable guide with no moving parts, fans or power draw, so it produces no heat or noise regardless of how long the rack runs.

Which rack hardware must already be in place for the 1UCMA-137 to mount correctly?

You need a standard 19 inch rack with either square or round mounting holes and at least 1U of vertical space on the left or right side.

Will the adjustable 28.5 to 33 inch extension of the 1UCMA-137 work with older Dell, HP or IBM sliding rails I already own?

Yes, the arm is designed for sliding equipment and its universal hole pattern fits legacy Dell, HP and IBM rails within that extension range.
