Ultra-Fab’s one-piece stabilizer chock anchors opposing wheels of tandem-axle trailers and fifth wheels, applying opposing force that prevents wheel roll on any surface regardless of slope. The chock collapses to just 1.5 inches for travel, expanding to 5.25 inches for full deployment when parked.

Steel construction with zinc plating resists corrosion, while the textured E-Z grip handle provides leverage during installation and removal. Super-grip tire louvers reduce slipping, and the optional padlock connection adds theft deterrence. Lifetime warranty covers manufacturing defects.
