We
have drained the water back out of the internal swing
sump sill past hinging co-extruded Santoprene anti
blow-back flap. |

|
On sub-sill installations there are two anti-blow-back flaps as shown lower left. |
|
•
|
The sub-sills are stop-ended as shown lower right. |

Another feature with our sub-sill installations is the central support leg that reduces the chance of dead load damage. |
