 The
RAINTROL® drain is offered in two basic designs. The three inch high weir is principally
for flat roofs. Though this may be used on sloped roofs, the limited factor is
the build up which can not exceed 3". The second design is the six inch weir
which can be used on all roofs up to and including a sloped roof with a 6"
rise. The flow rates for all RAINTROL® drains are shown Table
2.
NOTE: The roof drains are supplied in increments of weir openings.
They are shipped from the factory with the correct weir openings in accordance
with the specifications. However, should some requirements or conditions change,
the drain can be adjusted. Vandal proof fasteners prevent unauthorized tampering
with the setting.
