The EFB Elektronik 691651AGR.10 rack shelf is a 19" compatible shelf designed to provide a stable support surface for equipment in racks and cabinets. Constructed from light grey steel, the shelf combines durability with a clean professional appearance. With an overall width matching 19" rack standards and a useful width of 414 mm, it accommodates a variety of devices and accessories while maintaining secure attachment to rack rails.

Advantages

The steel construction offers high load capacity and resistance to deformation, while the light grey finish reduces visible wear and integrates with common server-room aesthetics. The useful width of 414 mm allows placement of many small-to-medium devices and peripherals. The unit is designed for straightforward installation in standard 19" racks and delivers a stable mounting surface for equipment that does not require dedicated rack ears.

How to use

Install the shelf by aligning it with the rack's 19" mounting rails and secure it using appropriate rack screws or mounting hardware. Place devices centrally on the shelf to maintain balance and avoid overhang. Ensure cables are routed safely and that ventilation around installed devices is not obstructed. For heavier equipment, verify the rack's load capacity and fasten the shelf at multiple points if possible.

Recommendations

Verify the weight of installed equipment against the rack and shelf load limits before permanent mounting. Use compatible rack screws and, where available, anti-slip pads or cable ties to secure items. Keep airflow pathways clear and allow space at the shelf edges for cable entry and exit.
