This is a genuine OEM sourced part used on the DeWalt DCST990M1 (Type 1) 40V 15" String Trimmer. The plastic and metal replacement spool is fastened to the gearcase assembly at the base of the trimmer. This item houses and dispenses the cutting line for trimming grass. A screwdriver is needed for the installation, and the replacement spool is sold individually.

Perfect fit
The replacement head for the weed eater was designed totally different, but in a better design. The old one wore through and broke before it even had 2 hours of time on it. The new one you send has an extra knob sticking down which allows for the bump feed to not wear out the spool.
Very happy with the product.

The replacement spool arrived on time, was in new condition, and has been successfully installed on the trimmer. Works great.

Awesome =ƒÿÄ Another home run for E Replacement Parts!
I thought I was only getting the housing for my trimmer string. But nooooo you sent me the whole assembly and filled it with string to boot! Another great reason for why I only buy from E Replacement Parts!

Removed line spool, removed 1/2\" nut holding the bump spring, slid the entire hub assembly off and replaced with the new one by aligning the new hub and bump spring on center shaft and replaced the 1/2\" nut hand tight. Super easy.
removed the old spool and put the new one on,just turn it off the spindle and screw the new one on,that simple,no tools required
