What this is
Two replacement chains for Ryobi’s 18V ONE+ HP brushless 10” chainsaw — the P2502BTL on its own, or the P2520 kit that comes with a 4Ah battery. Ryobi’s own replacement chain for it is RY10C1. This pack is the same size: 10”, 3/8” low-profile pitch, .043” gauge, 40 drive links.
Check before you order
- Count 40 drive links on the old chain. Ryobi writes this in its own shorthand: the RY10C1 page lists it as “Y40”.
- Make sure it is the 10” saw. Ryobi’s 18V 8” pole saws and pruning saws look similar in the range but take the shorter RY8C1 chain.
