Insulated Wire Ferrules


A plastic cover on the barrel provides electrical insulation to prevent short-circuiting with nearby wire. These wire ferrules add strength and stability to stranded wire to protect it from damage and speed insertion into terminal blocks. Use a crimper (not included) to install wire.
Use the ferrules for two wires to insert two wires into one terminal block.

Heat-Shrink Pin Terminals

When heat is applied, the insulation on these terminals shrinks, creating a seal that keeps out water and contaminants. The barrel is also insulated to prevent short-circuiting from nearby wire. These solid pin terminals make it easier to insert stranded wire into screw-clamp connections. Use a crimper (not included) to install wire.
