B-LINE SB5772303FB – Frequently Asked Questions

1) How many rack units does this B-Line blank filler panel cover?
Three mounting spaces, which is 3U of rack height. The panel stands 5.19 inches tall, matching the 1.75 inch per space pitch used on open frame racks. If you have a 1U or 2U gap to close, you need a different panel height.
2) What mounting hardware does the SB5772303FB blank panel use?
It is punched for #12-24 mounting hardware, the thread used on tapped-rail B-Line open frame racks. If your rack rails are 10-32 tapped or square-hole cage nut, the screws you have on hand will not thread into it.
3) Is this filler panel aluminum or steel, and how much does it weigh?
Aluminum, finished in flat black powder coat, and it weighs 2.12 lb. Light enough to hold in place one-handed while you start the screws, and the aluminum will not rust in a damp telecom closet or basement MDF room.
4) Do I need to specify anything else when ordering the SB5772303FB?
No options to pick. SB5772303FB is a single configuration: 23 inch width, 3 mounting spaces, aluminum, flat black powder coat, #12-24 hole pattern. Order by the quantity of 3U gaps you need to close.
5) Will a flat black panel match the rest of my black B-Line open rack?
The finish is flat black powder coat, the same finish B-Line puts on its black open frame racks, so it reads as a matched fill rather than a patch. For a facility standardizing on black racks across closets, ordering the same finish on every blank keeps the elevation uniform.
6) Why use a blank filler panel in an open frame relay rack at all?
A blank panel closes off unused mounting spaces so gear cannot be reached from the front, keeps cable from being pushed through empty rail space, and gives a finished front elevation. The SB5772303FB covers three spaces at a time, so it closes a 3U gap with one part instead of three separate 1U blanks.
7) How thick is this B-Line blank panel?
The panel stock is .09 inch. That thin profile sits nearly flush against the rack rail, so it does not push mounted equipment or front-side cabling forward, and the 5.19 inch face still covers the full three-space opening.
