Keep multiple sizes of our tightest-gripping butt splices on hand. After crimping your splice, apply a heat gun to shrink the plastic and grip wire securely under tension and vibration. The heat shrink also protects wire from the drips, dirt, and scuffs that lead to fraying, poor conductivity, and short circuits.

Keep different sizes of connectors on hand and twist them onto wires for quick installation.

Install and service setups for two, three, and five wires, then reuse these connectors later. They pop on and off wire with the flip of a clamp to save time over crimping. Choose them for setups that change often, such as prototypes and testing. They even have test sockets to safely test voltage after installation. The assortments include DIN-rail adapters so you can snap connectors into a control panel.

Keep a variety of welding lug sizes on hand. Either solder these welding lugs into place, or use a hammer-on crimper (not included) for a secure connection.

Install, extend, or rewire a circuit without hunting down new wire ferrules. These assortments include ferrules for most small and medium wire gauges.

Ferrules turn flexible, stranded wires into one rigid, straight wire that slides into spring-clamp and lever-clamp terminal blocks. When attaching your wire, use a wire ferrule crimping tool to avoid a damaged barrel and loose connection.

Install, extend, or rewire a circuit without hunting down new terminals. These assortments include ring terminals for most small and medium wire gauges and screws. Labels in the lid include our part numbers, so it's easy to replenish your assortment.

Ring terminals encircle the whole the screw shank, so they stay put better than spade and hook terminals when vibrated or pulled. Attach wire with a crimping tool to avoid a damaged barrel and loose connection.

Install and service setups for two to eight wires. These assortments include DIN-rail adapters so you can snap connectors into a control panel. Quick-connect push-on connectors are as fast to install as our clamp-on option, though they're not as easy to adjust. Push wire into place without the need for an installation tool. To break the connection later, you'll have to pull wire back out. The connectors also have test sockets to safely test voltage after installation.

Keep multiple sizes on hand to connect wire without crimping or wire stripping.

Keep multiple sizes on hand to splice any wiring in your facility. Insert wires end to end in the splice, then twist on the caps to lock the wire in place when vibrated and pulled.

Keep multiple sizes of wire taps on hand to tap any wiring in your facility. With a tighter grip than other insulation-piercing options, these taps secure connections around motors and other rattling or jolting equipment. Twist the cap to lock the tap onto the main wire. The tap will bite through the insulation to establish a connection. Next, strip your tap wire and thread it into the tap to draw power and create a new circuit.

These assortments include the set screw lugs, nuts, and bolts needed for single-phase and three-phase dry-type transformers (transformers that dissipate heat without using liquid).

Set screw lugs are easier to install than compression lugs, and they can be reused because you don't crush the barrel to attach the wire. They don't hold the wire as securely as compression lugs, however—use them when pulling and bending aren't a concern and you need to easily break your connection for maintenance or adjustments.
