    • Model #2101602
    • Model #2101602A (BST4000)
    • Model #2103002 (ST40B410)

Professional Styling:

Our replacement caps feature a sleek design with the following dimensions:

  • Diameter: 2.95 inches
  • Height: 1.265 inches

Each cap is crafted to hold the spool securely in place, ensuring that your trimmer functions optimally for every job.

High-Quality Material:

Constructed from PA66 (Nylon) with G30 (Glass Fiber), these caps are engineered for durability. The incorporation of glass fiber significantly enhances the stiffness, wear resistance, and heat resistance of the caps, extending their lifespan well beyond that of standard ABS plastic caps.

How to Confirm Suitability:

To ensure compatibility, identify the model code located on the product nameplate on the head of your lawn mower or refer to the instruction manual. For any inquiries regarding compatibility, we offer presales consulting service to assist you.

Ordering the wrong model may lead to trimming issues. If you have any uncertainties, please contact us before placing your order!
