CMZST065/CMZST0653 30 Feet 0.065'' String Trimmer Line Compatible with Craftsman Models: CMCST900,CMEST913, CMESTE920,CMESTA900,8-Pack (6-Line Spool + 1 Cap+1 Spring)

What It Is

This is an 8-pack replacement trimmer line kit (30 feet total, 0.065-inch diameter) designed for Craftsman battery-powered string trimmers. The kit includes 6 pre-wound spools, 1 cap, and 1 spring, making it a convenient all-in-one solution for routine line replacement.

Fitment & Compatibility

Check your model number against the list: CMCST900, CMEST913, CMESTE920, or CMESTA900. This is a genuine Craftsman accessory (part numbers CMZST065/CMZST0653). Before buying, confirm your trimmer uses a 0.065-inch line diameter—larger trimmers often require 0.080 or 0.095 line. Also verify your trimmer head is a bump-feed style; this kit won’t work on fixed-line or automatic-feed heads. Measure your spool width—should match the included spools (approx. 2 inches wide). Not compatible with gas-powered Craftsman models.

Key Things to Know

• Line gauge matters: 0.065-inch line is best for light trimming (grass, weeds) but will snap quickly on thick brush or against fences.
• Installation is straightforward: Pop off the old spool, drop in the new one with the spring, and snap the cap on. No winding required.
• Pre-wound spools save time: No tangles or uneven winding—just swap and go. The extra cap and spring are useful backups if you lose originals.
• Line durability is average: Expect to replace spools every 1–2 full yard trims depending on debris contact. Not for heavy-duty commercial use.

Should You Buy It

Buy this if you own one of the listed Craftsman battery trimmers and want a hassle-free, factory-fit line replacement for light to medium residential trimming. It’s a solid value at $9.33 for six spools, especially if you dislike winding your own line. Skip it if you need thicker line for heavy brush or have a different trimmer model.
