These probe ports will work on almost any smoker - just drill a hole and fasten the port to the cooker. No more crimping your wires, no more feeding them through the lid or the smoke stack! Features an adjustable port, allowing you to tighten the outer ring around the probes, preventing smoke from leaking out of the port. Made out of stainless steel. Ideal on smokers with a metal thickness of 1/4" or less. Thread length is 3/8" and the lock needs 1/8" to secure tightly.
