Our Approach
Our facility maintenance team implemented a heavy-duty exclusion strategy to reinforce the "Seal the Box" initiative:
Threshold Installation: We supplied and installed a 1/2" x 5" x 72" commercial-grade aluminum threshold. This added elevation successfully closed the 3/4" gap, providing a solid surface for the new sweeps to engage.
Multi-Layer Sweeps: To deter future gnawing, we replaced the compromised rubber with Xcluder® rodent-proof door sweeps. These were paired with 2-inch industrial brush sweeps to provide a secondary barrier against drafts, dust, and insects.
Vertical Gap (Astragal) Closure: We installed a new set of split astragals, precision-mounted to the surface of each door. This hardware effectively "locks" the vertical gap between the double doors when closed, completing the perimeter seal.
