Roll-N-Lock A-Series vs Roll-N-Lock M-Series — frequently asked
Roll-N-Lock A-Series or Roll-N-Lock M-Series — which should I buy?
Buy the Roll-N-Lock A-Series if you care most about weather. Buy the Roll-N-Lock M-Series if its balance suits you better. Both are the same type of cover, so the decision is about execution rather than category.
Is the Roll-N-Lock A-Series more secure than the Roll-N-Lock M-Series?
On our rating the Roll-N-Lock A-Series scores High for security and the Roll-N-Lock M-Series scores High. Treat that as resistance to an opportunist rather than as a safe — no tonneau cover stops someone determined with tools and time.
Will either of these fit my truck?
Both are sold per truck and bed length rather than as one universal part, so the answer depends on your year, model and bed. Most full-size & mid-size beds — confirm your year and bed length. Check your exact fitment before ordering either.
Do either need drilling to install?
Roll-N-Lock A-Series: Clamp-on, no drilling. Roll-N-Lock M-Series: Clamp-on, no drilling. Mainstream covers clamp to the bed rails and need no drilling, which keeps them removable and the truck's finish intact.
