Replacement crank handle for a Happijac truck camper screw jack, restoring the ability to manually lift and lower the jack system.
The Lippert 182436 is a replacement crank handle designed for use with Happijac truck camper screw jacks. These jacks, rated for 1,500 to 2,800 lbs. capacity per jack, are used to lift and lower a truck camper on and off a pickup bed. This 4" standard crank provides the leverage needed to manually operate the jack system, and is available in this standard 4" length or a longer 8" version for different reach needs.
This crank handle is designed for Happijac truck camper leveling/tie-down jacks, not RV slide-out room mechanisms. If a manual override crank for a slide-out room or landing gear jack is needed instead, that is a different part - such as Lippert's 3/4" hex manual crank handle (part #285324) used across many slide-out and jack applications.
