We appreciate your feedback and apologize for any issues you may have experienced with the HOM1RKCP retaining kit. Unfortunately, without knowing the exact Homeline Load Center you have, I cannot determine if this is the correct retaining kit to use on it. Please coordinate with Home Depot for their return policy and we would like to encourage you to contact our Product Support at 888-778-2733, option 2 to further assist you on this matter.
Warm regards,
Schneider Electric Customer Care
