    The Lock-N-Block is a portable, wall-mounted security fence that can be quickly collapsed or expanded and locked. This portable security gate is available in silver, black, or yellow/black industrial powdercoat, providing maximum durability with an elegant and professional look.

    Simply roll in and divide space securely with the Lock-N-Block for fast, efficient crowd control. Two wall-mounted lock plates are included with each Lock-N-Block room divider.

    The Lock-N-Block has extra-wide 28" caster bases for added stability, and 3" locking casters for easy transportation and smooth opening and closing over any surface. Rolling caster bases can be locked together (to prohibit unintentional opening) and allow the unit to easily be moved from one location to another. Tubular steel cross braces reduce pinch points over competitors' models.
