King Pin Stabilizer Tripod for 5th Wheel - "Fastjack"

by BAL
SKU 485199A

BAL’s king pin stabilizing jacks are designed to offer a more firm and stable camping experience by supporting the king pin hitch on a fifth wheel trailer.

Once the king pin stabilizing jack is installed, you can tension the jack against the hitch by tightening the patented foldable drive screw or tension ratchet.

This tension helps prevent movement associated with the heavy overhang of a fifth wheel trailer.

Features Include:

  • Full adjustability on each leg using a unique ratchet system
  • Each leg drops to ground and then applies tension independently
  • Large base pads for firm footing
  • Light weight yet sturdy design, lockable to trailer’s pin with included pad lock
  • Designed for use with 5th wheel trailers with a king pin height of 40 to 60 inches
  • Collapses to compact size to help with storage
  • Weight: 16.01 lbs
  • Ready to use straight out of box, no assembly required

Limited 1 Year Manufacturer Warranty
