    "Just what I needed. Needed new drain for shower. Local bigbox hardware store only had fine thread fittings. This one is coarse thread and matched existing."

    "Great experience. My shower drain assembly is 21 years old. I just needed the top piece. Big box stores did not carry the part. The drain fit perfectly and was easy to install. A link to an instructional video was included in package and was helpful."
