Sridet Topline was developed specifically for surface blasting. The Topline 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.
Sridet Topline consists of a coil of shock tube. One end of the coil is sealed and the other end is crimped to a Detonator with the required delay timings.
The Detonator is housed in a connector for surface hooking purposes.
Sridet Topline are 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.
