Prime-Line F 2653 Diecast Cam Action Window Sash Lock
This window sash lock is designed to replace or upgrade locks on single- and double-hung vinyl windows. It uses a diecast construction finished in antique brass for a classic look. The included mounting hardware simplifies install, and the cam action latch draws the keeper tight when secured, helping reduce rattle and improve security on aging sash hardware.
Key considerations: compatibility with common center-to-center hole spacing (1-3/4 inches), robust mechanical action, and an antique-style finish that blends with traditional window frames. It’s suitable for retrofit projects where a durable, long-lasting latch is desired and may require drilling of mounting holes for best fit.
Prime-Line F 2590 Sash Lock for Sliding Windows
This sash lock is tailored for vertical and horizontal sliding windows, providing a cam-action latch that engages into a fixed rail to secure the window. It comes as a replacement part with fasteners included and is compatible with a variety of aluminum-framed sliding windows. The lock’s keeper-free design can simplify installation while maintaining reliable security for homes with aging sliding sashes.
Considerations include its suitability for aluminum-framed systems, ease of installation, and the fact that it locks directly into the fixed rail rather than using a separate keeper. It’s ideal for upgrading or replacing worn sliding-window hardware to restore security without major hardware changes.
VIDABTE Window Locks & Latches for Andersen
Designed to fit Perma-Shield Narroline Double-Hung windows (1968–Present) and 400 Series Tilt-Wash double-hung models (1994–Present), this latch and keeper set offers broad compatibility for mid- to late-century Andersen replacements. The finish and build emphasize durability and aesthetic compatibility with classic window hardware while providing a straightforward replacement for aging lock heads.
Key points: replacement confidence for traditional brands, durable surface treatment for wear resistance, and a focus on restoring smooth operation and security without requiring a full sash replacement.
Hicarer 4 Pack Casement Window Locks
This set includes four casement window sash locks crafted from zinc alloy with a bronze finish. The design features a cam action hook that tightens the keeper when locked, helping deter intruders. The compact projection (about 1-1/4″) and base dimensions offer solid security without overwhelming small window openings. Aimed at casement applications where sash height is modest, these locks provide a durable, corrosion-resistant option for repeated use.
Considerations include its suitability for casement windows with the same slide rail alignment, installation screw size (M4x16mm), and the need for horizontal alignment to enable locking. The bronze tone also complements many wood and painted window frames.
HIMOMO Window Sash Locks, 10 Pack
The HIMOMO kit includes ten cam-action white sash locks with a large screw pack for multiple windows. The cam action design tightens the keeper when locked, boosting security for sliding and double-hung configurations. Zinc alloy construction enhances durability and wear resistance, while the included screws facilitate straightforward installation. The package target is bulk replacements or multi-window projects, delivering consistent performance across several openings.
Storage and maintenance considerations: ensure screws match hole spacing and that sash lines are level for proper locking. The multi-pack approach supports larger upgrades or ongoing maintenance for rental properties or multi-window homes.
Buying Guide
- Window type and compatibility: Determine whether your windows are single/double-hung, sliding, or casement, and check hole spacing, keeper design, and rail engagement to select a compatible latch.
- Material and finish: Diecast or zinc alloy latches with antique brass, bronze, or white finishes suit older frames while resisting corrosion and wear.
- Lock action and security: Cam-action latches provide a tight seal and deter prying; ensure the keeper integrates securely with the sash rail for reliable operation.
- Installation considerations: Some models include mounting hardware; others require confirming screw size and length (often M4-type). Check alignment and ensure windows are on a level plane for proper locking.
- Bulk packs vs. single replacements: For homes with multiple windows, bulk packs reduce ongoing replacement time and ensure uniform performance across openings.
- Keepers and compatibility: Some locks use integrated keepers; others require separate components. Verify that the chosen latch fits your window’s receptor design to avoid gaps or rattle.
- Maintenance: Periodic cleaning and lubrication of latching components help extend life and maintain smooth operation, especially on older wooden or vinyl frames.
