Great American Storage keeps keepsakes safe within roomy, temperature-controlled units watched over by security guards and video surveillance. Using complimentary handcarts or the center's free truck rental, customers tote trappings to the unit of their choice and barricade them behind a secure cylinder lock. Because each unit is climate controlled, belongings remain in pristine condition, safe from the warping caused by humidity, the melting caused by heat, or the gremlin liquefaction caused by excess water damage. 5'x10' spaces offer the space of a typical walk-in closet, snugly supporting the furniture and effects of a one-bedroom or studio apartment. Storers with more sizable stuff, such as bedroom sets, can opt for the 10'x15' unit, which measures at the size of a large bedroom or an incredibly large small bedroom. Security cameras keep tabs on any suspicious visitors or lovelorn impulse-buy racks, and an on-site post office lends easy passage of incoming additions or space-saving shipments. Great American Storage does not allow some items in storage units.
