Linear 2120-506-YS Complete Yellow Enclosure With Top for BGU Barrier Operators
The Linear 2120-506-YS is a complete enclosure assembly with top for the Linear / OSCO BGU barrier gate operator family. It provides the protective outer housing used around the internal mechanical and electrical parts of the barrier operator. In parking, access-control, and commercial lane applications, the cabinet is exposed to vehicle traffic, sun, rain, landscaping equipment, and service wear, so enclosure damage is common over the life of the operator.
This part is finished in yellow and should be used where the BGU parts documentation calls for the 2120-506-YS complete enclosure with top. It is not a complete barrier gate operator and does not replace the gate arm, gearbox, motor, or control system.

Technician Note
Barrier gate cabinets are often damaged by vehicle contact. Before replacing only the enclosure, inspect the operator base, internal brackets, gearbox, gate arm hardware, and control area for hidden impact damage.
Before Ordering Checklist
- Confirm the operator is BGU or a listed compatible BGU-related model
- Verify yellow finish and enclosure-with-top configuration
- Check whether door, locks, internal brackets, or decals are separate
- Inspect the operator frame for impact damage
- Confirm shipping method because enclosure assemblies may require special handling
Professional Advisory
Commercial gate operator service parts should be installed with power safely disconnected and the operator secured against movement. For high-voltage wiring, moving gate hazards, or uncertain field conditions, use a qualified gate technician.
Important Ordering Warnings
Do not interchange BGU, BGUS, SG, and other barrier gate enclosures by appearance only. Cabinet color, top style, door style, and mounting points can differ.
