ESI Ribbed Rectangle Rubber Seal .187” Height .500” Width 25' Length–EPDM Foam Rubber Seal with 3M 9485EK Acrylic Transfer Tape–Door, Window & Multiple Use Weather Seal. Fills height gaps from .100" to .168". To prepare your seal for application, cut to length with scissors or knife. Prior to installation, ensure bonding surface is properly cleaned with a 50/50 mix of denatured alcohol and water solution. Optimum performance is between 10% to 45% compression, with 20% being ideal – less than 10% compression makes the seal less effective, and over 45% places the seal at risk for compression set and failure. All products are made from an ESI custom formulated EPDM sponge rubber compound that guarantees protection from weather and noise for years to come. ESI (Extruded Solutions Inc) is a U.S. based manufacturer since 2008. MADE IN THE USA
