UNIVERSAL SIR must be deployed prior to disposal. Unlike drivers side modules, passenger side modules cannot be deployed in-car since collateral vehicle damage will occur. Also, they cannot be deployed safely on the floor or a bench as a drivers side module can, due to the unusual configuration and larger size of the module. GM-39401 is a weighted fixture that will securely hold all passenger side modules in a "bag-up" position for deployment. It features adjustable mounting arms, mounting hardware. Due to US Department of Transportation regulations all SIR modules must be deployed prior to any shipment and must also be deployed prior to disposal.
