Hook And Loop Tube
This was developed specifically for surface blasting. The Topline Hook And Loop Tube is used to provide the delay between the holes in the row and between the rows. Thus Topline helps to provide delay per hole in the blast and reduces the charge per delay in the blast, thereby reducing the ground vibrations, air blast pressure etc. Hook And Loop Tube consists of a coil of shock tube. One end of the coil is sealed and the other end is crimped to a with the required delay timings. The is housed in a connector for surface hooking purposes. Hook And Loop Tube is available in different delay timings, viz, Instantaneous, 17msec, 25msec, 42msec and 65msec. The connectors are provided in different colors to identify the delay timings easily.
