B-LINE SB5772090YZ – Frequently Asked Questions
1) Do I need cage nuts or 10-32 screws for this B-Line open frame rack?
Neither. The mounting rails on the SB5772090YZ are drilled and tapped 12-24, so you fasten gear with 12-24 rack screws straight into the rail. Square-hole cage nuts do not apply, and 10-32 hardware will not thread. Order 12-24 screws and washers to suit your equipment count.
2) Is this rack rated for a seismic installation?
The SB5772090YZ is a network bay open duct rack built for Seismic Zone 4 and it is UL Listed. That covers the highest of the legacy seismic zone classifications, which is why it gets specified in data rooms in California and other high-risk regions. Floor anchorage still has to follow your structural engineer's detail.
3) Should I use an open frame rack like this or a enclosed cabinet for my network room?
An open duct rack such as the SB5772090YZ gives you access from all four sides, unrestricted airflow and the easiest cable management, which is why it is the norm in a locked telecom room where physical security is handled by the door. Go with an enclosed cabinet instead when the gear sits in a shared or public space, needs lockable doors, or needs contained hot/cold aisle airflow. The open rack also has no side panels to remove when you are dressing large bundles at 51 rack spaces of density.
4) What footprint does this B-Line rack need on the floor?
The rack is listed at 90 in height, 19 in width and 90 in length/depth. Plan aisle clearance on top of that footprint for rear cable access and code-required working space in front of electrical equipment, since an open frame is worked from both sides.
5) How many rack units of equipment will this hold?
51 mounting spaces, which is 51 rack units of usable panel height. Budget a couple of those for horizontal cable managers and blanking if you are dressing a full bay, and remember the top channel style member sits above the mounting area rather than consuming rack spaces.
6) What is the finish on this Eaton B-Line rack, and is it suitable for an unconditioned space?
Steel construction with a yellow zinc finish, formed from ASTM A1011SS sheet. Yellow zinc gives corrosion protection for indoor telecom and electrical rooms. It is not a coastal or wash-down finish, so for damp or outdoor-adjacent locations specify an enclosed, gasketed cabinet instead of an open frame.
7) How much does the SB5772090YZ rack weigh, and can one person set it?
The rack weighs 121 lb on its own. That is a two-person lift to stand upright and plumb, and once loaded with switches and a UPS the total floor load climbs quickly, so confirm your slab or raised floor rating and anchor it through the base before loading equipment.
