This product is an orange alloy steel mini screw jack with a painted surface. It has a size adjustment range of 5 in. to 8 in. belonging to an adjustable deck support tool. It can also be used as a house jack, and its core purpose is to achieve the leveling of objects. The main body of the product is made of alloy steel, combined with a surface painting process, which provides basic structural strength and rust resistance. It is suitable for scenarios such as deck support and local house leveling-for example, adjusting the height of a deck to achieve levelness, or providing temporary support and leveling for local structural parts of a house. During use, the spiral structure needs to be manually adjusted to change the height within the range of 5 in. to 8 in. according to actual support requirements. During the adjustment process, it is necessary to ensure that the jack is in firm contact with the object being supported. This product is only an auxiliary adjustment and support tool. Its rated load capacity shall refer to the specific product specifications (if not marked, the general load standards of similar products shall be followed). It cannot be used in scenarios beyond the load-bearing range or non-leveling purposes, nor is it suitable for long-term, high-load structural support. It can only be used as a temporary adjustment or auxiliary support tool. When in use, it must be placed on a flat and hard ground to avoid support failure caused by unstable ground.
