PRO-GRADE 5000LB CAPACITY PER JACK:Engineered with heavy-duty cold-rolled steel (superior to standard iron), each screw jack withstands 5000lbs — 2.2X industry average. Galvanized + black oxide dual-layer anti-corrosion coating fights rust in crawl spaces/seaside areas.
90-SECOND SETUP: NO TOOLS NEEDED: No tools needed! Hand-twist the screw jack from 5"-8" heights-stabilize RVsteps or level floorboards faster than hydraulic alternatives. Hex-lock nutsprevent slippage-safety built In. PACK ULTIMATE COVERAGE: 40,000LBTOTAL
8 heavy-duty jacks deliver 40,000lbs total capacity — perfect for large-scale projects (e.g. sagging porches/roof beams). Outperforms 4-PC kits (like ASIN2) at 2X value, eliminating repeat purchases.
360° Full-scene Coverage Universal from RVS to buildings Secures RV One machine solves the needs such as RV stabilizer, roof repair, floor joist jack, and temporary stage construction for recreational vehicles; Compact design ADAPTS to narrow Spaces, truly an all-round engineering partner.
Thick 3mm steel tubes resist bending under load (vs. competitors' 2mm). Tightened hex nuts prevent slippage — critical for temporary structures. Backed by a 5-year rust warranty
