Linear 2120-144-BT Enclosure Without Door for HSLG and GSLG Operators
The Linear 2120-144-BT is the enclosure body without the front door for select Linear / OSCO commercial slide gate operators. It provides the main protective cabinet shell around the operator components, helping keep the motor, gear reduction assembly, control area, and mechanical parts properly housed. In commercial slide gate work, the cabinet is more than a cover. It supports service access, keeps components protected from weather and debris, and helps maintain the correct relationship between the operator frame and attached service panels.
This part is commonly used when the existing cabinet shell is damaged, rusted, bent, or no longer suitable for reuse. It is not the same as a complete enclosure with door, and it should not be ordered if the door, lock, or complete cabinet assembly is the part actually needed.

Technician Note
Before replacing the enclosure body, inspect the door, lock, hinge points, mounting points, conduit entries, and internal mounting hardware. Reusing bent or corroded companion parts can make a new enclosure difficult to align.
Before Ordering Checklist
- Confirm the operator family and model number
- Verify the needed part is the enclosure without door, not a complete enclosure assembly
- Check whether the existing door and lock assembly will be reused
- Inspect conduit openings and mounting points on the existing cabinet
- Review parts diagram for any hardware that must be ordered separately
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 assume 2120-144-BT replaces every Linear / OSCO slide operator cabinet. Similar HSLG, GSLG, GSLG-A, and VS-GSLG enclosures can have generation-specific differences.
