Description

Overview

The Curb Side Upper Frame Hinge Thermo King SB 300 330 supports the upper curb side door position on matched Thermo King SB units. When the original hinge wears, bends or loosens, the door can drop out of line. Replacing it helps restore smoother opening, cleaner alignment and more secure closure. This part suits SB 300 and SB 330 service work where the fitted upper frame hinge matches the original curb side position.

Features

• Aftermarket version under the ICS sellable SKU
• Helps restore upper door alignment when worn hinge hardware affects opening and closing
• Useful where the original hinge has loosened, worn at the pivot or suffered impact damage

Compatibility and Fitment

Check the hinge position before ordering, because upper and lower frame hinges are different. The curb side location must also match the original hardware. This part suits matched SB 300 and SB 330 models where the installed hinge follows the curb side upper frame position. This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. 92-0385, 920385

Compliance and Safety

Inspect the door frame, lower hinge, striker and mounting faces before fitting the new hinge. Then confirm the door opens freely and shuts square after installation. If the removed hinge shows impact damage or abnormal wear, inspect the mating hardware as well. That helps prevent uneven load on the replacement.

Trailer Applications
