A pullout shelf assembly for a retail merchandise display including a shelf, an adjustable length support arm and a latch arrangement is provided. The shelf has a product support surface. The first adjustable length support arm has first and second arm members movable relative to one another between a retracted position and a first extended position. The shelf moves with the second arm member. The latch arrangement has a first catch associated the retracted position and a second catch associated with the first extended position. A latch bolt secures the second arm member in the retracted position when engaged with the first catch and secures the second arm member in the first extended position when engaged with the second catch. The handle operably actuates the latch bolt out of engagement with the first and second catches to permit movement of the second arm member relative to the first arm member.
