Reliable Hardware for Sliding Doors and Casement Windows

Strike plates and keepers in this category are specifically engineered for use with sliding patio doors, hinged doors, and casement windows. By providing a durable metal surface for the lock or bolt to catch against, a flat door strike plate or auxiliary strike plate helps prevent wear on the frame and enhances overall security. Flat keeper plates are frequently used in dual-point and foot-operated locking systems found on many patio and sliding doors, making them an essential replacement part for maintaining secure closures and proper function.

Key Features and Specifications

  • Precision-made for direct compatibility with AmesburyTruth hardware and other leading brands.
  • Available in multiple sizes and hole configurations, including single-hole and dual-hole models for different locking mechanisms.
  • Material options like stainless steel and yellow dichromate steel offer corrosion resistance and long service life.
  • Some designs allow partial ventilation while keeping the door secured, ideal for added airflow without sacrificing safety.

Use Cases and Installation Tips

Strike plates and keepers are commonly replaced during lock upgrades, security improvements, or after signs of wear such as loose latches, rattling, or difficulty locking. When installing a flat strike plate or keeper, select the correct size and configuration for your door or window rail,many models, like the angled auxiliary strike plate, are designed for specific sill widths or materials (wood, vinyl, or aluminum). For example, a two-hole angled auxiliary strike plate provides a secure mount when the sill rail is too narrow for a flat plate. Always confirm compatibility with your existing hardware by matching part numbers or dimensions.

Popular product options include a flat keeper plate in stainless steel for enhanced durability, and a dual-point flat strike plate in yellow dichromate steel for corrosion resistance in challenging environments. For patio doors requiring partial ventilation, select a flat two-hole auxiliary strike plate that allows the door to be partially open yet still secure.
