6-Inch 1/4" Pitch Chain for Worx JawSaw WG320 / WG321 and Black+Decker Alligator Lopper (3-Pack)
$25★ 4.5 on Amazon
Aftermarket 3-pack in the 6" 1/4" pitch, .050" gauge, 42-drive-link size used by the Worx JawSaw (WG320, WG320.9, WG321), and the same pitch, gauge and length Black+Decker gives for its Alligator Lopper chain RC600.
Factory specs for each saw, taken from the manufacturer's own product page or manual (linked). Our chain matches every row on bar length, pitch, gauge and drive-link count.

Doesn't fit
Ryobi PCLCW01 18V ONE+ 6" pruning chainsaw — also 6", but its chain (A48CW02) is 3/8" low-profile with 28 drive links. (source)
What this is
Three replacement chains for small enclosed-bar saws: 6”, 1/4” pitch, .050” gauge, 42 drive links. This is the chain size in the Worx JawSaw manual (WG320, WG320.9, WG321).
A note for Black+Decker Alligator Lopper owners
Black+Decker uses one chain, RC600, for the LLP120 / LLP120B and the corded LP1000 Alligator Loppers. It describes RC600 as 6”, 1/4” pitch, .050” gauge — the same as this chain — but doesn’t publish the number of drive links. That is why the Alligator Loppers aren’t in the fit table: we only list saws where the maker publishes every number.
Before ordering, lay the old chain flat and count the drive links. If it is 42, this chain is the same size. The LLP120 manual also says the replacement chain must be a low-kickback chain meeting ANSI B175.1.
Not the same as 6-inch pruning saw chains
This is a 1/4” pitch chain for enclosed-jaw loppers. A 6” length alone doesn’t identify it: Ryobi’s 18V PCLCW01 pruning saw is also 6” but takes a 3/8” low-profile chain with 28 links. Check the pitch before ordering.
Fitting it
Both the JawSaw and the Alligator Lopper use an automatic tensioning system behind a bolted cover, so you need a wrench to open it rather than a tool-free knob.
Frequently asked questions
Does this fit my Black+Decker Alligator Lopper?
Black+Decker's chain for the LLP120, LLP120B and LP1000 is RC600, which it describes as 6", 1/4" pitch, .050" gauge — the same as this chain. It doesn't publish a drive-link count, so count the links on your old chain first: this one has 42.
What do WG320.9 and WG321 mean?
In Worx's JawSaw manual, the .9 version comes without a battery and charger, and the WG321 is the JawSaw with an extension pole. All use the same chain.
Can I sharpen it?
Black+Decker's support site advises against sharpening the Alligator Lopper chain and recommends replacing it instead.
