QCAA Zinc Die Cast Window Sash Lock 2-7/16 in, Brushed Antique Brass

In this review the QCAA Zinc Die Cast Window Sash Lock is judged as a budget-friendly solution for homeowners and handypersons who need a simple sash lock for double-hung windows. It is best for projects that require a matched finish across multiple windows or a quick replacement, thanks to the 12 pack and included mounting hardware. The single biggest reason to buy is the straightforward functionality: the crescent base design reliably draws frames together to reduce rattle when the parts fit properly.

Key Features

• Crescent base lock: Designed specifically for double-hung windows to pull the sashes together and reduce wind noise and rattle.
• Complete keeper size: The keeper measures 2-7/16 in x 11/16 in providing a defined contact area for a secure latch engagement on compatible frames.
• Clear center-to-center measurements: CTC values of 1-15/16 in and 2 in let an installer confirm fit before mounting.
• Mounting hardware included: Each 12 pack ships with the screws needed to install multiple locks without buying extra fasteners.
• Brushed antique brass finish: The finish offers a traditional look that blends with classic window trim and aged hardware styles.

Who It's For

The lock is aimed at homeowners, rental property managers, and contractors who need an economical way to secure and quiet double-hung windows across several openings, particularly when a consistent finish is desired. The 12 pack suits multi-window installs or replacement of all sash locks in a room.

Those who need heavy-duty, thick metal hardware or a high-end, precision-fit sash lock should look elsewhere; several customers report thin metal and occasional fit issues, so projects requiring durability under heavy use or custom-fit applications may benefit from a sturdier alternative.

Pros & Cons

Pros

• Easy to install with included mounting hardware, so a typical DIYer can fit several locks quickly.
• Effective at reducing sash rattle when the keeper and base align properly, improving window feel.
• Good value for covering multiple windows because the pack contains 12 locks in a matched finish.
• The brushed antique brass finish provides a classic appearance that matches traditional interiors.

Cons

• Metal is relatively thin and some users report issues with sturdiness or the latch separating from the base under stress.
• Fit is mixed across customers; measuring center-to-center carefully is important to avoid alignment problems.
