LEVEL 1
The EPDM rubber bonded washer creates a watertight seal on top of the L-foot.
LEVEL 2
The flashing is fit with an EPDM rubber grommet. When used with any EcoFasten compression bracket (milled with countersink), a watertight seal is created.
LEVEL 3
The cone-shaped EPDM rubber grommet envelopes the lag bolt completely, creating a watertight seal at the roof layer. When the grommet is compressed, the bolt is completely sealed in place.
LEVEL 4
The EPDM rubber grommet creates a watertight seal between the flashing and the roof deck, continuously functioning through all types of building movement.
