Extension Rod

Extension Rods in the Top Hammer system are available in lengths of 2m (unconventional), 3m and 3/6m (conventional) and in two types of double threaded (Extension Rod) and bushing (MF Rod). In the double threaded type, the connection between two rods is made through a coupling or bushing, but in bushing rods, there is no need to use a bushing, but the probability of rod failure from the bushing section increases.
