Select ‘SLOW’ for gentle, millimetre-accurate positioning of fragile fixtures, or ‘FAST’ for rapid ground release. Prevents sudden impacts and ensures steady, controlled adjustments throughout every installation phase. 【Heavy-Duty Support & Adjustable Reach】-Engineered with reinforced steel and aluminium alloy to deliver a robust 400kg combined load capacity (200kg per arm). The precision lift range spans [0–14.5cm / 0–24cm], providing reliable elevation for cabinets, doors, and heavy panels while maintaining structural rigidity under load. 【Integrated Measurement & Clamping Function】-The laser-etched measurement scale enables exact height matching and flawless alignment when deploying dual arms. Beyond vertical lifting, the unit securely functions as a timber clamp or fixed-gap spacer, preventing unwanted lateral movement during carpentry, framing, or fitting tasks. 【Reinforced Build & Anti-Slip Stability】-Constructed from high-strength alloy with a thickened structural frame for long-lasting site durability. The widened, textured contact base ensures maximum grip on uneven floors or workbenches, minimising slippage and enhancing operator safety when handling heavy or breakable materials. 【Compact, Portable & Multi-Scene Ready】-Lightweight and tool-bag friendly, this labour-saving jack streamlines drywall alignment, tile leveling, flooring support, and furniture assembly.
