INSTALLATION
1. Thoroughly clean the inside of the glass channel with
sandpaper to remove all rust and foreign matter.
2. Cut the new piece of glass channel filler 51 mm (2-
inches) longer than required.
3. Position the filler (soap stoned side away from the
glass) evenly around and over the edge of the glass
that will be inserted in the channel. Press the filler
firmly onto the edge of the glass to ensure a good
bond. (Usually this is done with a mechanical window
press.) Squeeze together the doubled ends of the
filler which project beyond the edge of the glass.
4. Brush the inner channel with soap solution. DO NOT
USE GREASE OR OIL.
5. Press the glass and the filler into the channel until
firmly seated.
6. Trim off excess filler material around, and at the end
of the channel.
