The 1,000 LB capacity XP10 offers the industry's strongest bolt-thru swivel mount system. This new mounting system eliminates the snap ring and produces less deflection under load and during operation than other bolt thru designs. The jack swings up and out the way in seconds. The stylized 6" caster allows for easy castering on all surfaces. Zinc plated for corrosion resistance. Provides 10" of screw travel and up to 25" of total lift. All mounting hardware included. Fits up to 3" X 5" trailer tongues.
