A:  Hello, Marilyn - Thank you for your interest in the REEL EASY + Serrated Blade Replacements (8-Pack). This would depend on the exact trimmer you have. The orange blades(AC053N1FB) are for trimmers with a bump feed. The green blades(AC052N1FB) are for trimmers without a bump feed.  Additionally, if you need further support, then a RYOBI Customer Experience Professional is here for you, Monday - Friday from 9 am to 6 pm (EST) when you call or text us at 1.800.525.2579 or through email or live chat when you visit us at https://www.ryobitools.com/support/contact.

A:  Hi, Carie. Thank you for your interest in the RYOBI REEL EASY + Serrated Blade Replacements. If there was a missing part in this package you would need to return it for a refund or exchange. However, it is possible that you purchased the incorrect blades. If the line is released by pulling the trigger then you will need to use the green replacement blades. If you bump the trimmer on the ground to feed out the line then the orange blades would be the correct blades. Thank you for asking, if you have further questions and would like to speak with a RYOBI Customer Experience Professional, all contact services are available Monday- Friday from 9am to 6pm (est) to contact us toll free please call 800.525.2579. Other methods of contact offered are email (24 hr response) or live chat, to speak with someone immediately at https://www.ryobitools.com/support/contact I hope this helps! - Jewel
