Notes:
Layout the radius or line you would like the outside face
of the edgers to follow.
Center the Insignia Edgers on the leveling pad with the
hard split textured surfaces up. Alternate A & B units
with the engled/stepped side edges interlocking and
fitting tightly together.
When building the minimum radius, all edgers should
have the wider sides facing to the outside.
