This item listing is for a Renolds Synergy 1/2" x 3/16" primary chain spare split link to fit a pre-1920 Douglas 2 3/4hp Model.
Always keeping a spare link in your toolbox and Renolds Synergy is their best chain and comparable to the old GP chain.
We also sell complete primary chains for this model - Item 0867, which again is the Synergy type.
Renolds Synergy is their best chain and comparable to the old GP chain. It costs about 2.5 times the amount of normal primary chain, but is worth the extra expense - and is excellent for open primary chains with little means of oiling. I am fitting it to my own 1919 Douglas 2 3/4hp model.
