SB120 Connector Housing
A durable SB120-style connector housing for building or repairing high-current quick-disconnect power connections. Ideal for batteries, chargers, DC-DC chargers, portable power systems, inverters, marine applications, RVs, solar systems, and other demanding DC power applications.
This listing is for ONE (1) SB120 connector housing only. Compatible SB120 contacts are sold separately, allowing you to choose the correct contact size for your cable and application.
Housing Only
This product includes one SB120 connector housing only. Contacts, handles, and complete connector kits are sold separately.
Why You'll Love It
- Replacement SB120-style connector housing
- Sold individually — one housing per unit
- Rated for 120A continuous power connector applications
- Colour-keyed housing helps prevent accidental cross-connection
- Use with compatible SB120 contacts in the wire size you need
- Ideal for batteries, inverters, RVs, marine systems, off-grid solar, and portable power builds
Colour-Keyed for Safer System Design
SB120 housings are mechanically keyed by colour, meaning different colours are shaped differently and will not plug into each other. This is useful when separating different voltages, battery banks, charging circuits, or equipment types — helping prevent accidental misconnection between systems.
Suggested Uses
- Battery quick-disconnect connections
- Off-grid battery banks and lithium power systems
- Medium-power inverter installations
- DC-DC charger wiring in trailers, vans, campers, and service vehicles
- Marine electrical systems
- RV power distribution
- Portable power equipment and service disconnects
- Solar power systems and charging equipment

Need a Complete Connector?
This product includes one SB120 connector housing only. If you're building a complete connector, you'll also need compatible SB120 contacts sized for your cable.
Frequently Asked
Is this a complete connector?
No. This product includes one SB120 connector housing only. To build a complete connector, you will also need compatible SB120 contacts.
Are contacts included?
No. This listing is for the SB120 housing only. Contacts are sold separately so you can choose the correct contact size for your cable.
How many housings do I need for one connection?
Most installations require two housings — one on each cable being connected. This listing includes one housing, so order two housings if you need both sides of a connection.
Do different colours connect together?
No. SB120 housings are mechanically keyed by colour. Different colours are shaped differently and are designed to only mate with the same colour and same housing size.
This can be useful for separating different voltages, battery banks, chargers, or equipment types so they cannot be accidentally plugged into the wrong system.
Can I use different colours for different systems?
Yes. That is one of the main advantages of colour-keyed housings. For example, you may choose one colour for 12V equipment, another for 24V equipment, and another for charging or accessory circuits. Since different colours do not mate together, this helps reduce the risk of accidental cross-connection.
Can I use different wire sizes with the same housing?
Yes. SB120 housings can be used with different compatible SB120 contact sizes. Choose the contact size that matches your cable for the best fit and crimp quality.
Will this fit other SB120-style connectors?
These housings are designed for SB120-style connector systems and are generally compatible with matching SB120-style components of the same colour and housing size. For best results, use matching housings and contacts from the same product series.
What else do I need to build a complete connector?
To build one complete SB120 connector end, you need one housing and two compatible SB120 contacts. To make a full mated connection between two cables, most installs require two housings and four contacts.
