Tymetal Corp.’s Positive Locking Ultimate Sallyport System includes the Bi-Parting model, which features fully enclosed positive drive assembly with a keyless three-point mechanical lock and is resistant to tampering and the effects of inclement weather.
The locking column is located in the center of the gate. The opening of chain link sliding gate panels is controlled from a set of remote “open-close-stop” push buttons.
The manufacturer also offers enhanced security by replacing chain link gates with heavy steel panels of 10-inch galvanized structural steel. These doors come with trolley wheels capable of handling door weights of up to 6,500 pounds.
