Installation GuideTetra® Contour Light Guide Forming Instructions
CAUTION / ATTENTION
Avoid direct contact between hot materials and exposed skin
or combustibles. Use heat resistant gloves while heating and/
or handling any hot materials. / Éviter tout contact direct
des parties chauffées avec la peau ou d’autres matières
combustibles. Utiliser des gants de protection thermique lors
du chauffage ou de toute manipulation des pièces chauffées.
CAUTION / ATTENTION
DO NOT use an open flame to heat the light guide. / Ne pas
utiliser une flamme nue pour chauffer le guide.
Heating and Forming
Part 1: Move the section back and
forth while rotating about the
diameter until it is soft and pliable.
Gently bend to the desired angle.
It is recommended to use a heat-
deflecting shield to distribute
the heat evenly. Avoid localized
overheating that may result in
distortion or damage (i.e. bubbling)
of the light guide.
For large bends, use either an industrial
oven or heating blanket. For small bends,
use a heat gun.
Part 2: The workable forming time
is about 2–3 minutes. The light
guide must remain in the desired
position until completely cooled. See
the chart above for minimum bend
radius guidelines.
Allow the light guide to cool by natural convection or lightly forced cool air (i.e. fan). Remove the Bend-Aids for
reuse. In order to remove any minor surface flaws, perform a light sanding using 400 grit sandpaper. Flared or
deformed ends can be trimmed. The light guide is now ready for light engine installation.
NOTE: DO NOT remove the Bend-Aids until the light guide has completely cooled.
NOTE: DO NOT subject heated light guide to freezing or quenching in water.
Heat gun
Preheat the heating equipment to
300°F (149°C). Heat light guides
approximately 6-15 minutes until
soft and pliable. Bend the light
guide over a printed pattern,
routed template, or use free-
forming. A clean flat insulated
surface (wood or laminated
countertop) will help to prevent
twisting or bowing. See the chart
above for minimum bend radius
guidelines.
