Patio Door

Before deciding on a patio door style, one typically considers visual appeal before all else. However, functionality may be an even more important factor in deciding the type of patio door that is best for you and your home.

While visual or curb appeal is important, the patio door style's functionality may have a much greater impact on the marketability of a home.  A French style patio door will open out to a deck or patio, creating the illusion of increased living space in the attached room.

Security and strength have always been a concern with french patio doors but thanks to Endura's Multi-Point Locking Ultimate Astragal, this is a thing of the past.

This Ultimate Astragal's multi-point locking system operates off standard deadbolt packages to make installation with existing door units easy. Combined with the strike and deadbolt, the additional engagement points create a total of five points of contact between each door, all without theneed for extensive machining. Not only does this enhance the door's strength but it keeps the door panel seated squarely in the frame, ensuring proper door to frame alignment and further preventing any air and water infiltration.

Homeowners get the best value for their investment.

The Multi-Point Locking Astragal is available in a number of aluminum and wood veneer finishes. For details on Endura's line of door component systems, contact an Endura representative or call 1-800-334-2006.
