The LiftMaster K99-12320-TPTEE is a heavy-duty traffic spike top plate assembly built for directional traffic-control lanes where the exposed teeth section helps discourage wrong-way vehicle movement. This is not a cosmetic cover; it is part of the working physical barrier that sees tire impact, weather exposure, and repeated vehicle traffic. The 3/8 inch plate thickness and dual 18 inch teeth-section layout make it important to match the installed spike frame before ordering. Use this part when the existing top plate is bent, worn, corroded, missing teeth, or no longer seats correctly in the traffic-control assembly.
