Using the Klein Tools VDV211-037 Crimp Die Set is easy. First, make sure you have the Klein's VDV200-010 Replacement Ratcheting Crimping Frame (hex crimp connectors sold separately). Then, select the appropriate coaxial cable (RG58, RG59, RG6, or RG62) and insert it into the die set. Place the cable and the connector into the crimping frame and apply pressure until the crimp is complete. When using, avoid applying excessive force that could damage the die set. For maintenance, keep the die set clean and dry. You can use a soft cloth to wipe it after each use. Store it in a cool and dry place to prevent rusting. If you need to change the cable type, it's a breeze to switch to another setting on this user - friendly die set.
