Introducing the latest product innovation from BAL to meet the needs of RVers: the new BAL "C" Jacks, combining the strength of a leveling jack and the steadiness you get from a stabilizing jack. Designed for use with travel trailers and fifth wheel trailers, there's no comparable product like the "C" Jack. Available in 19", 22", 25", 28" & 31" extension and shipped in a boxed set of two with crank handle. BAL "C" Type Stabilizers are designed to mount to the trailer frame where the crossmember meets the main frame member.
