They provide a secure area for the latch bolt of a door to engage, which helps keep the door closed and secure. Among various types of strike plates, extended strike plates are particularly useful for specific door installations. This guide will delve into the different types of door strike plate extensions, their applications, and technical specifications.

Understanding Extended Strike Plates

Extended strike plates feature a longer lip, allowing them to accommodate thicker doors or provide extra protection for door jambs. They are commonly used in scenarios where regular strike plates might not suffice. For instance, if you install a door that is thicker than the standard measurement, an extended strike plate will ensure that the latch can still engage properly, providing a secure closure.

Types of Extended Strike Plates

  1. T Strike Plates: These plates are characterized by their T-shape, which provides a more robust engagement with the latch. They are particularly useful for doors that are thicker than the average size. The Deltana TSPE225, for example, features a lip extension of 1-3/4 inches and is made from solid brass, making it a durable choice.

  2. Full Lip Strike Plates: These strike plates extend fully across the entire width of the door frame. They are ideal for custom installations and can accommodate a variety of door thicknesses. The Don-Jo 91xx-630 model is a notable example, made from 304 stainless steel and available in multiple lengths.

  3. Dimpled Strike Plates: Designed for use with ball and roller catches, these plates can come in various lip sizes. They are typically made from stainless steel and provide a satin finish, combining aesthetic appeal with functionality.

  4. ANSI Strike Plates: These are standard strike plates that comply with the American National Standards Institute (ANSI) specifications. They are suitable for general door installations but may not be ideal for specific applications requiring extended lengths.

  5. Electric Strikes: These specialized strike plates are designed for electronic locking systems. They often have unique dimensions and features to accommodate electronic components.

  6. Ball Catch Strikes: These strike plates are specifically designed for pocket doors, providing a secure closure when the door is not in use.

Applications of Extended Strike Plates

Residential Uses

Extended strike plates are commonly used in residential settings, especially in homes with thicker doors. For instance, if you have remodeled your home and installed solid wood doors, you will likely need extended strike plates to ensure that latches engage properly.

Commercial Uses

In commercial applications, extended strike plates can be crucial for maintaining security. Businesses often install heavier doors for added protection, making extended strike plates necessary. They also provide enhanced durability against frequent use.

Custom Installations

For custom door installations, extended strike plates offer flexibility. They can be tailored to fit a variety of door thicknesses and frame styles, ensuring a perfect fit and effective operation.
