Compatible with the Woodlander Large and Nomad View Large stove, the 3.5” Spark Arrestor is available as a replacement if the Spark Arrestor that came standard with your stove becomes lost or damaged. The fine wire mesh prevents sparks and embers from exiting the chimney pipe, a top cap keeps rain and snow out, and attachment points allow you to use guy lines to stabilize the flue in windy conditions.
