Brass Sash Lock Value Guide

These American-made brass sash locks from the 1890-1920 era represent a period where functional security met Victorian and Edwardian craftsmanship. They are highly collectible for historic home restorations due to their solid brass construction and ability to reduce drafts while securing sashes.

What affects the value of Brass Sash Lock?

• The presence of original mounting screws can slightly increase the value for collectors.
• Overall condition of the brass, including whether it has been over-polished or retains its original antique finish.
• Mechanical functionality, specifically the tightness of the locking mechanism and the smoothness of the lever.
• Intricacy of the design, as later pieces often featured more decorative elements than the early, purely functional models.

How to Identify Brass Sash Lock?

• Look for a heavy, solid brass weight rather than modern plated zinc or thin stamped metal.
• Check for a natural aged patina or oxidation consistent with hardware manufactured between 1890 and 1920.
• Examine the underside for potential maker's marks or patent dates common in early 20th-century United States manufacturing.
• Verify the mechanical cam-action lever which was designed specifically to pull double-hung sashes tightly together.

History of Brass Sash Lock

Sash locks became widely popular in the 19th century as a means to improve security and prevent drafts in homes with double-hung windows. Early designs were often simple, made from brass or iron, and emphasized functionality. Over time, designs evolved to include more decorative elements while maintaining their essential purpose of securing windows.
