American Metal Products Group is introducing the new AmeriVent Model ALK Flexi-Liner chimney liner kits. The complete aluminum kits include a flexible length, round top, flashing, and mortar guard. Made for venting gas appliances, the Model ALK chimney liner kits have a 5:1 compression ratio and come in small boxes, saving storage and truck space. The chimney liner is also said to be very easy to stretch out when taken out of the box.
