Andersen Trailer Jack Block | 3608 | Single, 2, 4 or 6 Pack

Stop fumbling with wood blocks under your stabilizer jacks. The Andersen 3608 Trailer Jack Block is a solid molded pad with built-in magnets that snap it onto the jack foot, so you set it once and it rides along as the jack extends. The recessed 9-1/8" pad area centers the jack and the 2-1/2" post hole captures post-style jacks so nothing walks or slips.
