The Safe Jack Stabilizer, No. 51M-SJS, designed for the hi-lift type jack helps make this jack safer to use and allows the jack to be used in ways that were previously impossible, according to the company. The stabilizer attaches in seconds to virtually any jack of this type and it does not limit jack operation. The 8" by 18" base plate is six times the base size of the jack, which helps reduce ground loading. Bracing cables steady the jack and support the jack standard. The stabilizer is available for 48" and 60" jacks.
