The 970 replacement blade assembly works with some Dahle 500, Dahle 507 and Dahle 508 personal rotary trimmers. Please refer to the notes below before purchasing:
Inspect your existing trimmer and take stock of:
- The shape of the blade assembly support bar (either round or square)
- The color of the blade assembly that you're replacing (either black or gray)
Next, reference the table to determine which assembly model is compatible with your trimmer.
