Tips and Additional Information

Before inserting the register plugs, inspect the vent opening for sharp edges, screws, or debris that could tear or puncture the foam. Ensure the register boot is clean and dry for an optimal friction seal. Push the foam plug evenly into the duct opening until flush or recessed securely. When removing, pull gently from the edges to avoid tearing the material, and store flat in a clean, dry compartment between jobs to maintain foam elasticity and shape.
