 • ALWAYS maintain a firm grip on the NONEL® tube or leg
Cast Booster wires while loading to prevent the loss of the initiation line. • Minimum detonator is No. 8 strength for temperatures above -40º C (-40º F). A high
 strength detonator is recommended for temperatures below -40º C (-40º F). Properties Cont. • ALWAYS use detonating cord with a coreload of 10.6 g/m (50 gr/ft) or higher when
 iniitiating the TROJAN RINGPRIME booster with detonating cord. • The detachable spider is designed to centrally locate and lock the TROJAN
