Working with basic principles of gravity, the wall-mounting design focuses all of its weight downward into the floor to hold hundreds of pounds. The additional unit is available in 18" and 33" dimensions and includes four shelves, which can be adjusted to any height, plus one aluminum profile. The profile, which can be placed on either side, features discreet side channels with sliding brackets that screw into the shelves for a fixed position (brackets must be inserted into profiles prior to wall mounting). This design allows for sturdy shelves that can adjust quickly and easily without the hassle of separate hardware. Leveling feet adjust for uneven floors. Made in Spain. Shown in image at left are one 33" complete shelving unit with two 18" additional units. Weight capacity per shelf is 110 lbs. The additional shelving units can be added to the complete system at any time, but cannot be used on their own.
