3Stair Rods
According to The Victorian Emporium, a renovation company specializing in period homes, stair rods were used to help secure runner carpets to wooden staircases. This unique feature was originally about both form and function. But these days, stair rods are more of an aesthetic item, since carpet is generally installed by stapling it to the surface below. It’s best for both you and your runner that your carpet is properly installed!
Where to find stair rods: Look for stair rods at specialty hardware stores or from rug manufacturers. You can also find them at retailers like Wayfair and Amazon.
