Alligator Teeth
pdfmini DOWNLOAD THIS DATASHEET

Alligator Teeth are designed to enforce traffic flow in one way systems such as car parks, hospitals, commercial, industrial and military sites. They are effective against all types of vehicles with high volume traffic flow.

Alligator Teeth

Alligator teeth utilize solid steel blocks as the moving part. Not only does this enhance the longevity, when combined with the rubber end stops, it also ensures quiet smooth operation.

Each tooth is 80mm wide and the blocks which rotate to 115mm high are 50mm wide and angled against reverse flow traffic.


The units are deployed in a single line across the road with 150mm spacing gaps. A support frame and 100mm drainage ducts are provided with the system which is set into concrete.

Rubber end stops, high performance grease retentive bushes, stainless steel axles and an all welded assembly ensure that Alligator Teeth provide a minimum maintenance solution.
