B-Line Eaton series single sided distribution junction kit, 140" height, 123" length, 9.25" width, Support terminal block cross connect, Universal di

It is a single sided universal distribution frame junction kit that serves as the support terminal block framework for central cross connects. In practice it is the steel skeleton you mount terminal blocks and cross connect fields on, single sided so it stands against a wall and is worked from the front only. It is the frame hardware, not the blocks or jumpers themselves.

Steel, specifically ASTM A36 structural steel. That is the standard hot rolled carbon structural grade, which is why this frame is treated as building structure rather than light sheet metal rack and is typically floor anchored and often braced to the wall or overhead.

Single sided, like the SB60914012TG, mounts flat against a wall and is accessed from the front only, which is the right call when floor space is tight and the cross connect field is small enough to work from one face. Double sided frames sit out in the room and are worked from both faces, which doubles termination capacity per linear foot but needs working clearance on both sides. Choose single sided when the wall is available and the room is narrow.

Order Eaton B-Line part SB60914012TG. That is the single configuration for this kit: 140 inch height, 123 inch length, 9.25 inch width, single sided universal distribution frame in A36 steel. There are no finish or size options to select.

No listings or certifications apply to this frame. It is structural support hardware for terminal blocks and cross connects, so the listed and rated components in the room are the blocks, protectors and cabling you mount on it, not the frame itself.
