Window security starts with one key part: the sash lock. This window hardware keeps sliding windows and double-hung window systems secure. It protects homes and businesses from break-ins. A high-quality sash lock also helps create a good seal where the two sashes meet, helping improve the thermal efficiency of the window.
Many manufacturers have shifted sash lock production overseas, chasing lower costs. However, Deco is proud to continue to service the market with entirely US made sash locks and window hardware.
For U.S. window and door manufacturers still purchasing US sash locks, local suppliers represent a strategic decision to invest in secure and responsive supply chain and the brand integrity of US made brands.
The Risk of Best-Price Sourcing
Outsourcing hardware components may appear cost-effective, but it introduces serious challenges.
Supply chains break down often. Shipping delays, tariffs, and global conflicts disrupt schedules and create unexpected costs for window manufacturers in the USA. These delays hurt delivery times. They also make it hard to ensure high performance in all zinc die-cast hardware.
When problems happen with overseas window security hardware, resolving defects is slow and costly. Dealing with issues across borders is time-consuming and expensive. Poorly manufactured zinc alloys or plastic parts can compromise both security and aesthetic appeal.
Why American-Made Window Hardware Works Better
Reshoring window components to the US brings clear benefits. In addition to the reliable quality, the investment in a domestic zinc sash-lock is an investment in reliability: Local suppliers allow customers to fix problems faster, expedite parts as needed, and connect with engineers when the needs of product designs change.
The industry standard zinc die-casting process used by US manufactures allows for strong, precise, and long-lasting parts. This high-performing approach to zinc die-cast parts results in locking mechanism components that offer better security.
Local suppliers make changes faster. Window manufacturers in the USA can adapt quickly to new requirements or special customer needs for their windows sash lock needs.
“Made in USA” signals reliability and craftsmanship to customers. Consumers value American-made products for their durability and trustworthiness.
Some customers want products that reduce carbon footprint through shorter supply chains. They also want to support US manufacturing jobs. This helps manufacturers stand out in fiercely competitive markets.
