from the bottom and space evenly thereafter, your last hole should be 100mm from the top of the guide.

from the bottom and space evenly thereafter, your last hole should be 130mm from the top of the guide.
Note which face of the guide is to be fitted to the wall (Spacing legs and or the saw cut away from fixing
wall). Now enlarge the fixing holes to 12mm* on the Inside face of the guide section to allow access to
the fixings and accept the hole cover grommets.
*Guides are supplied with black grommets – Drill 12mm hole.
To assist the smooth operation of the garage door a 25mm saw cut has been made at the top of both
guide sections on the internal face, and the guide should be splayed creating a funnel below the nylon
idler wheel on the head plate.
