Sash locks and keepers are critical window hardware designed to fasten and secure window sashes, ensuring your windows remain tightly closed and resistant to external forces. In casement, awning, and double-hung windows, these components work together: the sash lock (the locking mechanism) engages with the keeper (the strike plate or catch), pulling the sashes snugly together for a secure, weather-tight closure. This not only safeguards against break-ins and accidental opening, but also enhances energy efficiency by minimizing drafts and air leaks.

Where Sash Locks & Keepers Are Used

Sash locking systems are widely used in residential and commercial windows, including:

  • Casement windows (side-hinged windows that open outward)
  • Awning windows (top-hinged windows that swing out)
  • Double-hung and single-hung windows
  • Sliding sash windows

By securely fastening the sash to the frame or adjoining sash, these locks prevent unauthorized entry, rattling, and window movement in high winds, and help keep conditioned air inside your home or building.

Details, Compatibility & Installation

Our collection includes a range of genuine AmesburyTruth® window sash locks, keepers, and related hardware in a variety of finishes, handings, and mounting hole patterns. Models such as the Maxim 24 Series Multi-Point Sash Lock, Truth Keeper with 1-3/8-inch screw holes, and Encore Multi-Point Lock Assembly are engineered for compatibility with a variety of window brands and styles that use Truth hardware locking systems. For a wide range of replacement needs, we also offer options like the Left Hand Sash Lock, 2-3/8 inch holes and Strike/Keeper for casement windows.

When replacing a sash lock or keeper, always check the screw hole spacing, handing (right or left), and sash type to ensure a proper match. Installation generally involves removing the old hardware, aligning the new lock and keeper with existing holes, and securely fastening with screws. Proper alignment is crucial for smooth operation and a tight seal,incorrect installation can result in poor security or air leakage. For best results, follow the manufacturer's instructions closely or consult your window professional.

Frequently Asked Questions

How do I know which sash lock or keeper fits my window?
Check the brand (look for AmesburyTruth/Truth markings), measure screw hole spacing, determine window type (casement, awning, double-hung), and check for left or right hand operation. If you need help, compare your hardware with product images and details such as the Maxim Keeper in E-Gard finish.

Are these parts compatible with Andersen, Pella, or Marvin windows?
Many windows from these and other brands use AmesburyTruth hardware. Always match your part numbers and measurements or consult your window's documentation for compatibility.

Can I install a sash lock or keeper myself?
Installation is often straightforward with basic tools, but accurate alignment is essential. If unsure, seek professional help or follow detailed installation guides for parts such as the Non-Handed Awning Window Lock.
