FeaturesHappijac have been producing the highest quality camper jacks in the RV industry since 1963. Extensive camper jack research, testing, and development has led to the manufacture of the safest, highest quality camper jacks available today.
Safety First
Happijac's ACME Screw Jack offers the industry's first redundant safety check system in an ACME screw jack. By providing an additional fail-safe safety nut, Happijac's ACME Screw Jack protects you and your camper against mishap in the event of failure. The unique concave (cupped) footpad design reduces movement and provides greater stability than large, convex footpads.
Optimum Performance
Through precision manufacturing and the utilisation of a high quality, polished steel screw coupled with a space-age, self-lubricating, friction-reducing nut, Happijac's ACME Screw Jack is so efficient that its performance compares with many competitor's ball screw jacks! Providing over 34" (864mm) of lift, the Happijac screw jack can quickly and easily raise and lower camper with efficiency and complete control.
Strong and Appealing
Each Happijac Camper Jack features 2" (51mm) square tubing which not only matches the contours and lines of your camper, but also provides significantly more strength than round tubing.
The Happijac ACME Screw Jack can lift an astounding 1700 lbs (771kg).
Each Happijac Camper Jack is powder coated on both the inner and outer tubes to protect against rust and improve appearance. The unique "Happijac look" ensures quality, strength, and safety while enhancing the look of your camper.
Easy Installation
Each Happijac Camper Jack uses the same universal Z-bracket mounting system and hardware. Providing superior strength and security, the Z-bracket mounting system is easily installed and/or retrofitted onto almost any camper. Best of all, once installed you never have to change brackets again, regardless of the type of Happijac Camper Jack you place on your camper.
