Narrow sliding door keepers are specialized metal strike plates that interact with the locking hooks on sliding patio doors, ensuring strong, dependable security and smooth locking action. Engineered for use with narrow-profile doors and compatible with many popular dual point and single point lock systems, these keepers are a critical part of door safety and performance. Whether replacing worn hardware or upgrading security, selecting the correct keeper for your specific door model keeps your patio door operating like new.

Key Uses and Compatibility

Narrow sliding door keepers are commonly installed on the frame of vinyl, aluminum, or wood patio doors where a tight fit and secure lock engagement are required. These keepers are made to accept the hooks or bolts from dual point locks (which secure the door at two separate points for added strength) or single point locks. The available widths and raise heights,such as 5/8 inch or 3/4 inch wide, with heights from 1/2 inch up to 1 inch,allow for precise matching to your current door hardware. AmesburyTruth, a leading manufacturer, supplies keepers for well-known window and door brands, making it easier to find the right fit for Hurd, Cascade, and other systems.

  • Widths: 5/8 inch (narrow) or 3/4 inch (standard)
  • Raise heights: 3/8, 1/2, 5/8, 3/4, or 1 inch
  • Compatible with dual point and single point locks
  • Material options include durable zinc or stainless steel

Choosing and Installing a Replacement Keeper

For the best results, carefully compare the measurements of your existing sliding door keeper to the product specifications before purchase. Many keepers look similar but have slight differences in width or height that affect installation. Matching the exact raise and profile ensures proper engagement of your lock's hooks or bolts, preventing security issues or difficult operation. If your current keeper is corroded or bent, a new AmesburyTruth keeper restores reliable performance. Installation typically involves removing the old keeper with a screwdriver and aligning the new part in the same mounting holes,no special tools required.

For example, you may need a keeper with a 1 inch raised dual point strike for tall lock engagement, or a 3/4 inch raised dual point keeper when working with mid-profile door frames. If you are looking for a stainless steel option for coastal or humid environments, this 1 inch raised dual point strike is a popular choice. Single point applications may require a raised 3/4 inch single point strike for secure latch engagement.
