The rod support is a product that is attached to the mast of a drill around 1/3 the way up the mast from the deck. It is designed to serve two primary purposes on a drill. First, it acts as a centralizer while drilling. It also supports the drill pipe from sagging while the mast is laid down or during tramming. This rod support is a direct replacement for Atlas Copco and Epiroc drill rigs, and can be customized for other drills as well. Contact us for more details on this specific product.
