What this is
Two replacement chains in the 16” size Oregon sells as S56: 3/8” low-profile pitch, .050” gauge, 56 drive links. Husqvarna calls the same pitch “3/8” mini” and sells it as S93G or H37. It fits the saws in the table above when they have a 16” bar: Husqvarna’s 120 Mark II, 130, 135, 240, 439 and T435, Ryobi’s RY3716 and 40V RY40550 / RY40505, Homelite’s UT43122 / UT43123, several Remington electric saws, the HART 40V HLCS021VNM, the Makita UC4051A, WEN and more.
Check the bar and the gauge
- Husqvarna 135, 240 and 120 Mark II are sold with other bar lengths too. The original 135 ships with a 14” bar, and the 120 Mark II and 240 also approve an 18” bar; this chain fits only the 16”.
- .043” or .050”? The other common 16” chain is .043” gauge — see our .043” 16” chain for DeWalt, Milwaukee and Makita XCU04 saws.
- Greenworks sells both gauges in 16”, and its own pages don’t agree on every model. Our Greenworks 16” page lists what Greenworks’ manuals say; go by the stamp on your bar.
Fitting it
The Husqvarna 135 Mark II uses side chain tensioning, and Husqvarna recommends only the bar and chain combinations it lists. The WEN 40417 and Makita UC4051A have tool-free chain adjustment.
