Product Features & Sizes

Zafety Lug Lock® is produced in an ISO-9001-2008 certified facility.

Zafety Lug lock® is formulated from design engineered plastic formulated to withstand extreme changes in temperature.
The standard formulation is designed to withstand continuous operating temperatures of -40 degrees Centigrade (-40°F) to +100 degrees Centigrade (+212°F) with transient temperature spikes up to +120 degrees Centigrade (+248°F) giving it a total transient operating temperature range of 140 degrees Centigrade or 252 degrees Fahrenheit.

The high temperature Zafety Lug Lock® engineered plastic was developed specifically to address the conditions in high temperature environments created by frequent stop vehicles. Vehicles requiring the high temperature Zafety Lug Lock® product typically include public transportation vehicles (city buses) and refuse trucks.

The high temperature formulation is designed to withstand continuous operating temperatures from -40 degrees Centigrade (-40°F) to +160 degrees Centigrade (+320°F) with transient temperature spikes up to +232 degrees Centigrade (+450°F) giving it a total transient operating temperature range of 200 degrees Centigrade or 360 degrees Fahrenheit.
