|  This clip has 20 degree offset jaws to guard against shorting. | 
                                                
                                                
                                                
                                                  |  The AL21C clip in addition to a single penetrator pin near the fulcrum has a cluster of hardened needles (nickel plated to prevent rust) which insures penetration of insulation on 22 gauge, 24 gauge etc. Wire. | 
                                                
                                                
                                                
                                                  |  Two or more wires may be penetrated at once for a temporary "splice". | 
                                                
                                                
                                                
                                                  |  The insulation "heals" as needles are withdrawn. Stripping of insulation is unnecessary. |
