The Dnigh Trailer Jack Block uses a reinforced, high-density rubber compound to resist compression and environmental wear while a patterned base keeps the block firmly in place on dirt, gravel, and pavement. These blocks are portable, stackable for extra height, and compatible with most scissor and tongue jacks as well as stabilizer pads.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Dnigh block improve stability while parked?\u003c\/h3\u003e\n\u003cp\u003eBy increasing contact area and resisting deformation, the block reduces trailer movement and the transfer of load into the jack foot.
