Yes. The SB5766138YZ is a 23 inch wide open frame rack, which is the standard footprint for mounting 19 inch EIA panels and equipment on its two uprights. The rails come drilled with 12-24 panel mounting holes, so any panel or cage-nut-free device with 12-24 hardware threads straight in without adapters.

48 mounting spaces, which is 48 rack units of continuous panel space on a frame standing 138 inches tall. That is a taller-than-typical network bay, so check your ceiling height, cable tray clearance, and any overhead sprinkler offset before you set it.

The SB5766138YZ is built as a seismic zone 4 network bay open duct rack, and it is UL Listed. If your facility is in a high seismic region and the drawing calls for a zone 4 rated bay, this is the configuration to specify rather than a standard open frame.

An open frame bay like the SB5766138YZ leaves all four sides exposed, so cable access, patch field dressing, and airflow are easier and you get all 48 spaces without door or side panel clearance. It gives you no physical security and no dust control, so if the room itself is not locked, or the equipment sits in a shared or public area, a locking enclosure is the better choice. Open bays are the norm in secured MDF and IDF rooms where technicians work the patch fields daily.

The frame weighs 136 lb on its own and stands 138 inches tall, so it is a two-person set at minimum and the bay has to be anchored to the floor, and typically braced overhead, before any equipment is loaded. Plan the anchor layout against the 23 inch footprint width.

It ships as the open frame bay itself, with a top angle style top and 12-24 drilled uprights. Vertical cable managers, horizontal wire managers, shelves, power strips, and the floor anchor hardware are all separate items you order to suit the build.

The finish is yellow zinc over steel, a plated corrosion-resistant coating rather than a paint. It will not visually match black powder coat bays, so if you are extending an existing lineup of black racks in the same room and appearance matters, expect a difference. The steel itself is ASTM A1011SS structural sheet.

Top angle refers to the angle members across the top of the frame. They tie the uprights together and give you a surface to attach overhead ladder rack or cable runway to, which is how these open duct bays are normally landed in a telecom room.
