Installing a new sash runner, or spring bronze may be required when a gap is preventing the windows from closing and opening easily. These strips of bronze are tied or stapled to the lower sash edges in order to prevent the rattling of the sides. They are available at DIY stores. Tubular vinyl weather-stripping is another option, but it is prone to rip, and it can detract from the appearance of windows.
When installing replacement runners for sash it is essential to measure the entire width of the window opening. It is best to take measurements from the top of the sash up to the horizontal line on the meeting rail and from the bottom sash down to the sill.
