Pro-Tip for Facility Maintenance
The Pemko S88W is the "go-to" seal for general-purpose fire door remediation. Its 1/4" height is perfect for standard gaps, providing a reliable seal without causing latching issues or increasing closing force. For a professional, long-lasting bond, the frame surface must be completely clean and dry; a quick wipe with an alcohol-based towelette to remove dust and oils is essential before pressing the adhesive into place.
