Liftmaster K99-12320-TPTEE, 3/8" TOP PLATE, 2-18" TEETH SECTION
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.

Technician Note
For K99-12320-TPTEE, the safest match is the original part number and the specific LiftMaster traffic-control parts diagram. Do not rely on appearance alone, especially with Cobra, King Cobra, Stingray, Viper, and CR plate variations.
Before Ordering
- Match the original part number on the removed part or parts list
- Confirm the traffic spike family: Cobra, King Cobra, Stingray, Viper, Enforcer, or other LiftMaster system
- Check plate thickness, tooth count, CR designation, shaft length, bearing size, or sign type when applicable
- Inspect surrounding hardware for wear so the new part is not installed against damaged components
- Do not substitute a similar-looking part unless the manufacturer parts diagram supports it
Important Ordering Warnings
- Similar LiftMaster traffic spike parts may not be interchangeable
- CR, surface-mount, concealed, in-ground, and standard versions may use different hardware
- Traffic lanes should be blocked and secured before service
- Warning signs and safety instructions should remain visible and intact
Professional Advisory
Traffic spike systems can create severe tire damage and should be serviced only with the lane secured, the system locked out where applicable, and all warning signs and traffic-control procedures in place. Do not modify the system or remove required warning devices.
