ABSTRACT:
A venetian type blind has a length adjustable bottomrail to fit windows of different lengths. The bottomrail has a channel at each ladder location through which the lift cords and the cord rails pass. A separate channel can also provided for the lift cord. An opening is provided in the underside of the bottomrail at each ladder location and an insert is disposed therein. The lift cord passes through the channel and attaches to the insert. The cord rails pass through the channel and out through the opening. The insert has a head portion with a bore therein. A threaded plug is installed in the bore. The head portion preferably has a rim portion with apertures through which the cord rails can pass. The threaded plug preferably has a cap portion and a pocket therein for storing the ends of the cord rails. Alternatively, the threaded plug is inserted into the opening itself. To adjust the length of a blind having this length adjustable bottomrail, two slats at the desired length are clamped together and the excess slats are removed. The empty rungs are cut through the middle. The threaded plug is loosened and slack in the cord rails is taken up by pulling the cord rails through the opening in the bottomrail. The excess length is cut off and the ends of the cord rails are stored in the pocket in the cap portion.
