Support sagging floors and foundations with the Ellis Manufacturing Screw Jack, SJ-4 and SJ-6. Select appropriate screw jack and cut lumber to appropriate length. Add Ellis MFG Joist Holders to secure posts to beams and joists. For extra lifting power use a 2x4 to turn screw. Also see Ellis MFG Light Duty and Heavy Duty Steel Shores for extra lifting and support. This video depicts sagging joists in home crawl space.
