VIABRICO Straight-Shaft Trimmer Head Replacement 10-Pack — Compatible with Echo/SHIandaiwa, High-Capacity Bump Feed

VIABRICO’s trimmer head is a durable, straight-shaft replacement compatible with many Echo/SHiandaiwa models that delivers high-speed trimming up to 10,000 RPM and stores extra line for fewer reloads.

This 10-pack replacement bump head is designed for homeowners and pros who need a reliable, high-capacity spool for straight-shaft string trimmers. Constructed from reinforced material, each head resists cracking and supports continuous operation at elevated rotation speeds. The units accept common line diameters and include pre-cut lengths so you can swap heads and get back to work quickly.

Which trimmer models will this VIABRICO head work with?

These heads were made to fit a broad set of Echo and compatible straight-shaft trimmers as well as several SHIandaiwa machines. Confirm your machine uses an M10 x 1.25 mm bolt and a straight shaft — the head is not compatible with curved-shaft trimmers or models requiring adapters.

• Compatible Echo models: Speed Feed 400, SRM-210, SRM-225, SRM-230, SRM-250, SRM-265/266, SRM-280, GT225 and more.
• Compatible PAS series: PAS-210, PAS-211, PAS-225, PAS-230, PAS-231, PAS-260, PAS-261, PAS-265, PAS-266, PAS-280, PAS-2100, PAS-2400, PAS-2601.
• Compatible SHIandaiwa: T195S, T220, T222, T230, T231, T242, T2510 and variants listed by the manufacturer.
• Mounting specification: bolt M10 x 1.25 mm; female hole diameter 10 mm (0.39").

How much line does each head hold and what line sizes fit?

The spool is sized to accept a range of common cutting line diameters and arrives with preloaded line to reduce downtime. Line wheel dimensions and high-capacity storage let you run longer between reloads, while the bump-feed design simplifies line advancement without disassembling the head.

• Included line length per head: approximately 6.56 ft pre-cut.
• Supported line diameters: 0.080", 0.095", 0.105", and 0.130".
• Line wheel height: 0.59"; width: 0.20" for better line organization.
• Reloading: bump-feed action, no full disassembly required.

Is the VIABRICO trimmer head durable and safe at high speeds?

VIABRICO uses a strengthened polymer to reduce risk of cracking and extend working life under heavy use. The head is rated for operation up to 10,000 RPM — suitable for professional-grade straight-shaft trimmers when properly installed and used within the manufacturer’s guidelines.

• Material: reinforced composite for impact resistance and longevity.
• Max rotation speed: 10,000 RPM when mounted on compatible trimmers.
• Designed to minimize breakage during regular trimming tasks.
• Do not use with curved-shaft models or without correct mounting hardware.

How easy is it to change the line or install the head?

Installation and reloading were simplified so you can change heads and lines quickly on the job. The assembly aligns using keyed holes, and line replacement requires only threading and turning the cover — no complex teardown.

• Installation: align holes and secure with the correct M10 bolt (not included).
• Line replacement: thread line through the hole, then rotate cover clockwise to tension.
• No adapters included; ensure straight-shaft compatibility first.
• Each package contains ten preloaded heads for bulk replacements.

Who is this for: This 10-pack is aimed at property managers, landscaping contractors, and active homeowners who maintain multiple trimmers or prefer stocking spare heads. If you use straight-shaft Echo, PAS, or compatible SHIandaiwa trimmers and want a sturdy, high-capacity bump-feed head that reduces downtime, the VIABRICO set is built to fit those needs without adapters or complicated setups.
