Electric Jack Ratings??

[Griz14]

How do they rate an electric trailer jack? When it says it is rated 4K with 18" lift, is that referring to the tongue weight or the trailer weight?

Thanks,

All force bearing on the jack, which includes not just the trailer's gross tongue weight but also the weight of the tow vehicle as you elevate the rear in order to more easily mount weight distribution spring bars.

Okay that makes sense.
