N737410 String Trimmer Head Compatible with De-Walt String Trimmer,Fit for Models: DCST922B,DCST922P1,DCST972X1.Replacement Spool with Pre-spooled Line,Pre-Wound Dual 0.080" Line for Trimming

What It Is

This is a replacement trimmer head assembly and pre-wound spool for DeWalt string trimmers. It is designed for edging and trimming grass or weeds, specifically for cordless models DCST922B, DCST922P1, and DCST972X1.

Fitment & Compatibility

Check model number first. This head is confirmed to fit only the three DeWalt models listed: DCST922B, DCST922P1, and DCST972X1. It will not fit other DeWalt trimmers or universal shafts without modification.

Measure the shaft. The head attaches via a standard threaded arbor. Verify your trimmer’s shaft diameter and thread pitch (typically 10mm x 1.25 left-hand thread for these models). If your trimmer uses a different attachment system, this will not work.

OEM vs aftermarket. This is an aftermarket part, not a DeWalt OEM replacement. It is functionally identical but may have slight differences in fit tolerance or durability.

Key Things to Know

• Pre-wound spool saves time. The spool comes with 0.080-inch line already wound. You can install it in under a minute without winding or measuring.
• Line thickness is fixed. This head uses only 0.080-inch line. Thicker or thinner line may not feed properly or could break the head.
• Installation is straightforward. Unscrew the old head (left-hand thread – turn clockwise to loosen), screw on the new one, and lock the spool in place. No tools required.
• Durability concerns. Some users report the plastic housing cracks after heavy use or impacts with hard surfaces. Not ideal for commercial or rocky terrain.

Should You Buy It

Buy this if you own one of the three listed DeWalt trimmers and want a quick, ready-to-use replacement head with pre-wound line. It’s a decent budget option for residential trimming. Skip it if you need a heavy-duty head for frequent use or prefer to spool your own line in custom lengths.
