Description

Overview

Thermo King Secondary Lock Spring fits the secondary door latch position on compatible Thermo King door hardware. It keeps tension on the secondary lock, so the latch can return and hold properly during use. When the old spring stretches, breaks or loses tension, the secondary lock can stop moving cleanly.

Features

• Fits the secondary lock spring position on supported door latch hardware
• Listed for SB and Spectrum door applications
• Helps restore latch return tension and lock movement
• Useful when the original spring has stretched, broken or lost tension

Specifications and Materials

Thermo King Secondary Lock Spring covers a small latch spring used in the secondary lock mechanism on supported units. Match the spring location and latch layout against the old part before ordering, because door hardware uses more than one spring and latch piece. Part number: TK-92-3877.
