Ratchet type axle stands, VS2002, VS2003, VS2006 and VS2012 models with cast iron support posts and VS3000 and VS6000 models with steel support posts. Both types feature angled teeth in posts, which prevent accidental release of load - the more weight applied, the tighter the post is locked. Heavy-duty VS12000 has cast support post with double pin securing for added safety. All have tough steel plate welded bases.
