EFB-Elektronik 1U 19-inch Heavy-Duty Shelf, Depth-Adjustable 500-900 mm, 150 kg, for 800-1000 mm Cabinets, Black

The EFB-Elektronik 691653TS.80 is a 1U heavy-duty 19-inch shelf with a 150 kg load rating and a depth adjustable from 500 to 900 mm, for 800–1000 mm deep network and server cabinets that need to carry UPS units, tower servers or heavy appliances.

Unlike a front-only cantilever shelf, it must be fixed to both the front and rear 19-inch profiles, which is what allows the 150 kg rating. The mounting depth is set with self-tapping screws, and the shelf takes only 1U of rack height. Finish: Black RAL 9005.

• 1 × heavy-duty shelf

• 150 kg is enough for a rack UPS without rails, a tower server laid flat or a stack of appliances.
• Adjust the depth once to match your profile spacing, then fix with self-tapping screws.
• Only 1U tall, so it wastes little rack space under heavy equipment.
• Cage nuts and screws for the rack profiles are not listed in the box — use your cabinet's own M6 hardware.

• 2-post racks or wall brackets — the shelf needs front and rear profiles.
• 600 mm deep cabinets — there is a separate EFB version for them.
• Sliding access — it is a fixed shelf.
• 10-inch or 23-inch racks.
