Face Plate Lock Spring (414534) for Singer 300U
Ensure your machine’s face plate remains securely closed during high-speed operation with this Face Plate Lock Spring (Part #414534). Specifically designed for the Singer 300U and United Sewing Machine NR models, this spring provides the necessary tension to hold the housing in place while allowing for easy access during maintenance.

Key Features & Benefits
Consistent Tension: Engineered to provide the exact pressure required to lock the face plate, preventing it from rattling or vibrating loose during heavy-duty sewing.

High-Resilience Spring Steel: Manufactured from premium-grade spring steel that retains its shape and "snap" even after years of opening and closing the machine head.

Precision Fit: A direct replacement for part #414534, ensuring a seamless installation that matches the original mechanical specifications of the Singer 300U series.

Vibration Dampening: Helps reduce noise by keeping the face plate firmly seated against the machine frame, contributing to a quieter workspace.
