Questions about this item
Does the 265DCCSEN require any tools or permanent fixtures to install on a sliding window track?
No, the telescoping steel bar uses pressure-fit ends so it wedges securely in the track without screws, brackets or drilling.
Will the 265DCCSEN still fit if I keep my existing 27-inch narrow sash?
Yes, the bar adjusts from 27-1/2 to 42 inches, so it spans a 27-inch opening once extended past the minimum length.
