A locking strip installation tool is necessary when installing window locking strips like those on the front windows 1940s and 1950s Spartans and on most vintage Bolers. This kind of gasket was used on the door windows on other 1950s trailers, too.
This tool's unique design allows the tip to swivel 90 degrees in either direction to work where straight tools would not.
Just select the tip with opening that most closely fits locking strip, and then feed locking strip into eyelet. Tip swivels in 90 in either direction. Two double-ended tips will have the sizes necessary to fit most all applications.
