Shakespeare 90-ft Spool 0.155-in Spooled Trimmer Line

What It Is

This is a pre-wound spool of 0.155-inch diameter trimmer line, 90 feet total, designed for gas and electric string trimmers that accept a universal or Shakespeare-brand spool. It’s meant for medium-to-heavy trimming of weeds, grass, and light brush.

Fitment & Compatibility

Before buying, check your trimmer’s spool housing: this spool fits most straight-shaft and curved-shaft trimmers that use a standard 0.155-inch line diameter and a pre-wound spool design (common on brands like Troy-Bilt, Craftsman, Ryobi, and Echo). Measure your existing spool’s width and shaft type—this spool is about 3.5 inches wide. It may not fit some compact or mini spool housings. If your trimmer uses a bump-feed head, confirm the line exit holes are 0.155-inch compatible (some heads require 0.095 or 0.130 line). It’s an aftermarket replacement, not OEM for most brands, but fits many universal heads.

Key Things to Know

• Line thickness: 0.155-inch is thicker than standard 0.095 or 0.130 line—good for heavy weeds but may wear faster on high-RPM trimmers.
• Installation: Usually a simple drop-in—align the line ends with the exit holes and snap the spool into the head. No winding needed.
• Common gotcha: Some trimmer heads require the line to be wound in a specific direction; this spool is pre-wound, so verify your head’s rotation (clockwise vs counterclockwise) before inserting.
• Durability: Shakespeare line is a round polymer—decent for general use but not as long-lasting as twisted or serrated line in rocky areas.

Should You Buy It

If you need a quick, no-wind replacement for a universal trimmer head and your trimmer handles 0.155-inch line, this spool is a solid value at roughly $0.23 per foot. It’s best for homeowners with medium-sized yards and standard weeds—skip it if you need a specific OEM fit or run a lightweight electric trimmer that requires thinner line.
