PIT66 Manual Rear Sliding Window Latch

The PIT66 latch is designed to fit Ford F-Series trucks (F150 1997–2004 and F250 1997–1999) with rear sliding windows. It adheres to OE standards to ensure compatibility and durability, using ABS plastic to resist impact and daily wear. This lock provides a straightforward mechanism for securing the rear window, helping to prevent accidental openings while enabling controlled ventilation when needed. When replacing OEM parts, verify compatibility with the vehicle’s year range and part number F65Z1527158AA to ensure a proper fit.
4 Pack Adjustable Sliding Window Locks

HRLORKC offers a practical set of four adjustable window locks designed for window rails with thicknesses from roughly 0.59″ to 1.26″. Each lock measures 2.4″ by 1.6″ by 1″ and features a gray finish to blend with most interiors. The locks are installed by closing the window, inserting the leg into the groove, and turning the knob to secure. The multi-pack approach is ideal for households with multiple windows or heavy usage where enhanced security is desired for doors and large vents alike.
Rear Sliding Window Lock Latch, Toyota/Tacoma Fits

The HQRNYP rear window latch is an OE-style replacement compatible with several Toyota models from 1989 to 2000, including Tacoma and Hilux variants. The latch features a robust plastic construction designed to resist wear, corrosion, and water exposure. It emphasizes reliable engagement to keep the sliding rear window secured, while matching the OEM replacement numbers (such as 69370-35010) to help confirm fitment before purchase. This option suits owners seeking straightforward, durable maintenance parts for mid- to late-90s Toyotas.
Dorman 76985 Sliding Window Latch

Dorman’s 76985 is a direct replacement sliding window latch designed to restore function on select Chevrolet and GMC models. While primarily marketed for GM vehicles, this latch emphasizes compatibility and reliable performance after the original part fails. The product stresses durable construction and longevity, ensuring the latch maintains secure engagement under typical driving conditions. Buyers should confirm exact model compatibility to ensure a proper installation and long-term operation.
Prime-Line U 9819 Aluminum Sliding Window Security Lock

The Prime-Line U 9819 is a four-pack aluminum sliding window security lock designed to secure metal horizontal sliding windows. The thumb-turn screw enables simple installation and secure locking in a closed or ventilated position. This option emphasizes a sturdy metal construction for durability and long service life, making it suitable for upgrades to existing window security across multiple rooms or vehicles where metal components are preferred for resilience and easy maintenance.
Buying Guide
- Compatibility: Check the make, model, year, and window type (sliding rear, vertical, or horizontal) to ensure the lock fits properly. OEM numbers or part compatibility lists aid accuracy.
- Material and durability: ABS plastic vs. metal (aluminum) affects resistance to impact, weather, and wear. Choose based on expected exposure (sun, rain, mud) and durability needs.
- Installation: Some locks require no tools, while others require simple hand-tightening or a basic drill. Consider ease of installation and whether a multi-pack is beneficial for multiple windows.
- Security level: For households with children or pets, prioritize locks with robust engagement mechanisms and multiple fixing holes for stability.
- Maintenance and wear: Look for corrosion resistance, especially for outdoor or exposed installations. Replacements should be readily available and documented with compatible part numbers.
- Versatility: If you own multiple vehicles or windows of different sizes, a universal or adjustable lock can reduce the number of parts you need to stock.
- Aesthetics: Finishes (gray, black, aluminum) should complement interior styling while not compromising function.
