Key features

• •Complete Accessory Set: This package contains 6 essential sewing machine parts, including 2 small spool cover, 2 large spool cover, and 2 vertical spool pin. The combination provides options for different spool sizes, offering a convenient solution for replacing lost or damaged thread holder components
• •Precise Dimensions: The small cap features a 3.3cm/1.3in base, while the large cap has a 4.4cm/1.73in base; both utilize a 0.6cm/0.23in hole diameter. The accompanying spool pin measures 6.3cm/2.48in in length with a 0.5cm/0.19in top width. Please verify these measurements against your machine's existing setup
• •Compatibility and Limitations: Designed for compatibility with most standard home sewing machines, including many models from brands like Janome, Singer, and Viking. Note that due to differing configurations, this set is not guaranteed to fit embroidery machines and specific compatibility should be verified prior to use
• •Spool Stabilization: These accessories are engineered to hold thread spools firmly in a vertical position during operation. By securing the spool against the pin, the covers prevent slipping and reduce erratic movement, which assists in maintaining consistent thread tension and minimizing tangling risks
• •Tool-Free Installation: Constructed from durable, thick plastic, these parts are designed for immediate use without technical setup. The installation process is straightforward; simply slide the spool pin into the machine base and secure the thread with the appropriate cap size, requiring no special tools or equipment
