Bumper installation instructions
Step 1: Make sure the aluminum channel and end caps
are installed.
Step : Use silicone lubricant to help the
bumper slide into the channel.
Step 3: Starting on one end: while inserting the bumper,
push it up against the end cap to prevent
the bumper from shrinking after installation
(when it gets cold).
Step 4: As you insert the bumper into the channel with
one hand, pull the bumper toward you with
the other to open the inside lips. Slowly
apply pressure by rolling the bumper into
the track.
