Barker VIP power jacks

[timarti]

Does anyone know how to measure for these? The Barker VIP jacks are sized 2" or 2 1/4" for the 3000 or 3500. The sleeve on my current manual jack is 2 1/4 and the pipe that extends and retracts is 2", so I am not sure which part is for the reference measurement and which would fit. Can't see the actual hole in the frame to measure, plus it is below zero out there right now! Will be heading to the RV show in Toronto at the beginning of March, so might find a deal.

yes, measure the circumference around the jack above the 3 mounting bolts. If it is about 6.25 inches then it is a 2 inch shaft if it is about 7 inches it is a 2.25 inch diameter shaft.

Do not measure the part that moves. It is the sleeve that extends thru the hole in your trailer.
