Buying Guide: Key Factors To Consider

  • Height range: Match the jack’s height range to the space you’ll work in. Shorter ranges are more maneuverable, while tall ranges cover ceiling or attic-level work.
  • Load capacity: Ensure each jack can bear the expected load, with room for safety margins. For heavy loads, use multiple jacks and solid base support.
  • Construction quality: Look for steel type (Q235 or similar), robust locking mechanisms, and corrosion resistance if used in damp areas.
  • Ease of use: Lever or screw adjustments, swiveling top plates, and tool-free height changes reduce setup time.
  • Stability and safety: Check for locking pins, wide base plates, and proper alignment features to minimize tipping risk.
  • Number of units: Sets with multiple jacks provide balanced support and reduce load per jack, which is important for uneven floors.
  • Space and access: In tight crawlspaces, a compact top plate and swivel design can make adjustments easier.
