B-Line Eaton series open racks, Steel, Yellow zinc, 12-24 panel mounting holes, 43 mounting spaces, Throat style, Closed duct unequal flange rack-ope

The SB5761108YZ gives you 43 mounting spaces on a 108 inch tall frame, so a full-height run of equipment can be mounted without stacking a second rack. Panel mounting holes are 12-24 tapped, which means equipment threads straight into the rails without cage nuts.

Yes. The rack is 19 inches wide, the standard EIA rackmount width, so any 19 inch panel or chassis lands on the rails. Just note the holes are 12-24 threaded, so you'll need 12-24 rack screws rather than 10-32 or M6 hardware.

Yes, and check the doorway too. At 108 inches the frame is nine feet tall, so you want ceiling clearance above that for cable drop and any overhead ladder rack, and the rack has to be walked in and stood up on site. In rooms with lower slab-to-ceiling height a shorter rack is the better call.

The unequal flange closed duct channel runs vertical cable inside the upright rather than strapping it to the outside face. That keeps patch and power runs off the equipment faces and out of the way when you are servicing gear. It is a throat style frame, so access to the channel is from the side of the upright.

Shipping weight is 126 lb for the frame itself. That is a two-person set and stand, and it is bare frame weight only, before any equipment load. Plan floor anchoring accordingly, since a nine foot open frame carrying loaded gear is top-heavy until it is bolted down.

UL Listed, yes. That is stated for the SB5761108YZ frame, which is what most institutional and government spec sheets ask for on equipment racks in an IT or telecom space.

Built from 11 gauge steel to ASTM 569 with a yellow zinc finish. Yellow zinc is a plated corrosion-resistant finish rather than paint, which suits indoor electrical and telecom rooms including unconditioned ones. It is not a color-matched architectural finish, so if you need black to match existing racks in a visible space this is not the one.

An open frame like the SB5761108YZ makes sense in a secured, dedicated room: both sides of every device stay accessible, airflow is unrestricted, and you are not paying for doors and side panels. Go with an enclosed cabinet instead when the equipment sits in a shared or public area and needs to be locked, or where dust and physical protection matter.
