B-LINE SB5879138TG – Frequently Asked Questions
1) Will my gear mount directly, or do I need cage nuts for this B-Line telco rack?
No cage nuts. The rails are drilled and tapped 12-24, so equipment bolts straight in with 12-24 screws. Square-hole gear that ships with cage nuts and M6 hardware will need 12-24 screws instead, and any equipment with universal-width brackets will land on the standard 19 inch panel pattern.
2) Is this B-Line rack rated for a seismic zone 4 installation?
Yes. The SB5879138TG is built as a Seismic Zone 4 network bay closed duct rack and is UL Listed. Seismic performance depends on the anchorage as much as the frame, so the base has to be bolted to the slab per the engineer's detail.
3) What is the footprint and weight of the SB5879138TG rack for planning the room?
Width is 23 inches and the frame weighs 151.98 lb bare, before any equipment. At 138 inches tall it needs vertical clearance to stand it up, and floor loading should be figured on rack weight plus loaded gear.
4) Is this rack heavy enough gauge for loaded switch gear, or is it a light-duty frame?
The frame is 11 gauge steel to ASTM A1011SS, which is the heavy end for open frame telco bays. Mounting holes run in the base, the uprights and the top channel, so load paths are tied top and bottom rather than into the uprights alone.
5) Should I use an open frame rack like this or an enclosed cabinet for a network closet?
An open frame bay like the SB5879138TG gives you all-around access for patching and airflow with no doors to swing, which is why it is the norm in MDF and telco rooms. Pick an enclosed cabinet instead when you need physical security, dust control, or directed front-to-back cooling. This frame has no doors, sides or locks.
6) Will this rack match the telco gray equipment racks already in my MDF?
Finish is telco gray powder coat over steel, the standard central office gray used across the Eaton B-Line open rack line, so it lines up with existing telco bays. Style is top channel, which lets you run ladder rack and cable runway off the head of the frame.
