B-LINE SB5772303AL – Frequently Asked Questions

1) How many rack units does this B-Line blank filler panel cover?
Three mounting spaces, which is 3U. The panel height is 5.19 inches, matching the 1.75 inch per rack unit spacing on a standard EIA rack. If you have a 1U or 2U gap to close, this one will overlap the adjacent equipment.
2) Do I need to buy screws separately for this filler panel, and what thread?
The panel is punched for #12-24 mounting hardware, which is the thread on the rack rails it is made for. If your rails are tapped 10-32 or use cage nuts, the hole pattern still lines up on rack unit spacing but you will need the matching fasteners for your rails.
3) What is a blank filler panel actually for in an open frame rack?
It closes an unused 3U opening in the rack face. In a rack carrying active gear, blanking the empty spaces keeps exhaust air from recirculating back to the equipment intakes, and it gives a finished front on a rack sitting in a visible space. The SB5772303AL does that job on 23 inch wide racks.
4) Is this blank panel aluminum or steel, and how much does it weigh?
Aluminum, in a brushed aluminum finish, weighing 2.12 pounds for the 3U size. Light enough that a full column of blanks adds almost nothing to the rack load, and aluminum will not rust in a humid MDF or a garage-level telecom closet the way a painted steel blank can once the coating is scratched.
5) Can I order more of the exact same panel later to match the ones already installed?
Order by manufacturer part number SB5772303AL and you get the identical brushed aluminum 3U blank. For a facility standardizing a rack elevation across multiple closets, that single part number is what keeps the faces matching.
