Sock holder
Sock holder is a complex of special clips on one of the slats of the case (sometimes on several), which allow you to more rationally hang socks, underwear and other small wardrobe items.
Hanger holder
The presence in the design of the drying rack of special devices for the placement of coat hangers. Such devices can be made as separate stands, and in
outdoor models(see "Type") they often have the form of openings at the ends of rigid rods that form the frame.
Technically, most drying racks allow you to use regular rods to place hangers, however, special
holders for hangers are much more convenient: in particular, when using them, the hanger will not move (whereas it can move back and forth along the rod), and there will still be a place on the main surface completely free.
Transport rollers
The presence of
rollers or other similar devices that allow you to roll the structure along the floor. Drying racks usually do not weigh so much as to create problems when carrying, even quite large ones; but with laundry hanging out, moving from place to place without rollers can be quite a challenge. In addition, transport rollers are often found in models with 3 — 4 tiers, which are inconvenient to carry, not so much because of their weight, but because of their bulkiness.
Dimensions (unfolded)
General dimensions of the drying rack in working position, taking into account all additional elements — side wings (see above), retractable parts (see "Design"), etc. This parameter will allow you to estimate how much space is required to use a particular model.
Dimensions (folded)
General dimensions of drying rack in the folded position. The smaller they are, the more convenient this model is in storage and transportation.
