Select Tight Knot (STK) Inter-grown (live) knots are the major characteristic of Western Red Cedar STK. This product is our specialty. Securing high quality raw materials and monitoring our in-house quality control procedures during processing ensures a high recovery factor. We carry large volumes of 2 x 3 to 2 x 12 rough, kiln-dried industrial STK. Our large inventory allows us to quickly ship product to industrial accounts for further manufacture, or as finished product to distributors, in large or small volumes. We run most patterns.
