The base and top plates measure 8 by 8 inches, providing a solid footprint and good stability when placed under beams or slabs.

Weighing 55 pounds, it is reasonably portable but somewhat heavy to move frequently without help.

Keep in mind the need for an additional adjustment rod and its weight when planning your work.

However, the product is on the heavier side, weighing 44 lbs, which might pose challenges during installation or repositioning.

However, at 32 pounds, the jack post might be somewhat cumbersome to handle for those not accustomed to heavy-duty tools, and the installation might require additional manpower or equipment in some cases.
