Total working surface
Under the total working surface is meant the total length of all drying rods in the expanded state. The
longer this length, the more laundry can be placed on the dryer and, usually, its maximum load is higher (see below). At the same time, this parameter also affects the dimensions and price of the device.
Max. load
The highest weight of laundry that can be dried (of course, we are talking about wet laundry). In addition to the general weight limit, the detailed specifications can also specify the allowable load on each individual rod.
At home, it is impossible to accurately control compliance with this limitation, but it is still worth taking measures to prevent overload. After all, although many drying racks have a certain margin of safety and can carry a lot of weight without visible consequences, off-design loads on the structure reduce its durability and increase the risk of unexpected breakdown.
Number of rods
The number of individual rods provided for in the design of the drying rack. The more such rods are provided for with the same total working surface, the shorter the length of each of them and the more compact the dimensions of the device in the unfolded state can be. On the other hand, short rods are poorly suited for sheets, blankets and other large items.
