Cross-frame telescopic stabilizing jacks for travel trailers and 5th wheels. 30" leg with 8" drive nut extension. Fits frame widths 62"–70". Vintage style design for Airstream, Avion, and Argosy-style trailers. Chrome speed crank handle and mounting hardware included. Set of 2.
The BAL 30930 is the 30" version of BAL's Deluxe Telescopic Stabilizing Jack set — a cross-frame stabilizer designed for travel trailers and 5th wheels with frame widths between 62" and 70". The telescopic cross-member design allows the two jack legs to slip into each other and be adjusted to span the underbody frame width exactly, without requiring a fixed-length crossmember or pre-drilled mounting points.
The 30930 features the classic vintage-style look closely associated with Airstream, Avion, and Argosy trailers — making it the natural choice for owners of these iconic rigs looking for a period-appropriate replacement or upgrade. Like the 24" 24830, it uses high-strength steel construction with rust-inhibitive coatings, a 3/4" chrome speed crank handle for operation, and an 8" drive nut extension that provides the reach needed to engage the jack from underneath without awkward positioning. No existing frame crossmember is required — the unit installs by bolting or welding directly to the trailer frame.

Per BAL's own product page: do not use a cordless drill or cordless impact wrench to operate this jack unless the drill has an adjustable clutch set to feel resistance. Use the included crank handle for normal operation. Using an unadjusted impact wrench can damage the jack mechanism and void any applicable warranty.
Select based on your trailer's underbody frame width. If your frame width falls between 62"–70", the 30930 is the correct model. If your frame width is wider (64"–74"), the 24830 is the correct choice. Measure your frame width at the underbody jack mounting location before ordering.
