The SPT5144B from Stinger is a 25-pack of 4 gauge black crimp ring terminals in chrome finish with a 1/4 inch ring opening, designed for negative ground connections in 12V automotive and car audio installations. The black colour coding identifies these as ground terminals by convention, and the 1/4 inch ring opening suits the standard stud size found on battery terminals, distribution blocks, amplifiers, circuit breakers, and fuse holders.
The SPT5144B is the ground counterpart to the SPT5144R red positive 25-pack, providing a matched bulk supply of black negative terminals for professional installers and workshops that regularly work with 4 gauge ground cabling across multiple installations. The crimp-on design allows fast, efficient termination without a set screw or allen key, requiring only a crimp tool suitable for 4 gauge wire.
The 1/4 inch ring opening is a smaller stud size than the 5/16 inch ring used in the SPT5104B and SPT5101B packs, suiting a different range of connection points including battery negative terminals, chassis ground points, circuit breakers, amplifiers, and fuse holders where 1/4 inch studs are used. Used alongside the SPT5144R red 25-pack, the SPT5144B provides a complete positive and negative terminal supply for 4 gauge installation work.

What is the difference between the SPT5144B and the SPT5104B?
Both are 25-packs of 4 gauge black chrome crimp ring terminals. The SPT5104B has a 5/16 inch ring opening suited to distribution blocks, battery terminals, and amplifier power connections that use a 5/16 inch stud. The SPT5144B has a 1/4 inch ring opening suited to battery negative terminals, chassis ground points, circuit breakers, and fuse holders that use a 1/4 inch stud. Confirm the stud size at your connection point before selecting between the two.
Does the SPT5144B pair with a matching red positive terminal pack?
Yes. The SPT5144R is the matched 25-pack of red 4 gauge crimp ring terminals with the same 1/4 inch ring opening, providing a complete positive and negative terminal supply for 4 gauge installation work when ordered alongside the SPT5144B.
Are these terminals suitable for positive power connections as well as ground?
The black colour coding identifies these terminals as negative ground connections by convention. They are electrically compatible with positive power connections, however for a professional installation it is recommended to use black for ground and red for positive to maintain clear polarity identification throughout.
Do I need a crimp tool to install the SPT5144B terminals?
Yes. A crimp tool suitable for 4 gauge terminals is required for correct termination. Contact us if you need guidance on selecting the correct crimping tool for these terminals.
What stud size does the 1/4 inch ring opening fit?
The 1/4 inch ring opening fits standard 1/4 inch studs found on battery terminals, distribution blocks, chassis ground points, amplifiers, circuit breakers, and fuse holders used in car audio and 12V automotive installations.
