Repair part worked perfect
The blade and screw for my Black n Decker weed wacker were exactly what I needed. Fit perfectly, arrived quickly and so much cheaper then buying a new weed wacker.

Great source for hard-to-find parts.
I had just about given up on locating this part for my 'old' string trimmer. Fortunately, eReplacementParts.com had it in stock. Quick shipment. Part received and installed. Very pleased.

Blade and screw fell off the guard during use allowing to much string to be fed out.

Figured that the line was not being cut by trimmer. Ordered the part for just $1.24. Now the trimmer works like new and it is 12 years old. A screwdriver was the only thing necessary to remove the old blade and replace the new part.
Really appreciate not having to replace my trimmer.
