18 inch curtain rod

Listings most often show metal construction: steel and iron are common, and at least one adjustable rod is described as aluminum.

Tension-style rods use an adjustable mechanism that presses against the inside of window or door frames, letting them fit without drilling or permanent hardware; listings describe these as steel for added stability.

Most product descriptions recommend simple upkeep: wipe the rod with a soft cloth to remove dust and keep finishes looking fresh.

Some adjustable cafe-style rods are listed as compatible with both inside- and outside-mount installation and include dedicated finials for each mounting style, with complete mounting hardware provided.

Many listings show an unextended length of 18 inches and commonly extend to about 28 inches; at least one listing extends to 30 inches.

Hardware varies by model. Common options shown include: inside- or outside-mount brackets, pocket rods with two end brackets, and tension-style rods that require no permanent hardware. Many adjustable rods include mounting brackets, screws, and anchors; exact components differ between listings.

Listings name a range of finishes, including enameled, polished, smooth, nickel-plated, and various brushed finishes.
