Bottom Astragal

The included astragal creates a flexible seal along the bottom edge of the rolling door.

When the door is fully closed, the astragal compresses against the floor to help reduce:

• Air infiltration

• Drafts

• Dust

• Dirt

• Debris

• Light penetration

• Minor moisture intrusion

A properly maintained bottom seal can also help compensate for minor irregularities in the floor surface.

Rolling door components can vary by:

• Door model

Always verify the existing slat profile and bottom-bar configuration before ordering.
