Will this fit a husky 540i?

This should fit the battery powered husky 540I Top Handle Saw.  You will most likely need to acquire a 1/4" pitch sprocket and pair it with our Archer Chain

This bar was built to have a "universal" tail mount. We haven't had a chance to personally test it on some of the new Husky electric saws. When we do we will come back and update this answer. In the event it doesn't fit we will always take the bar back on a return.
