A compact 3-port 4GA T-distribution block from the Stinger PRO Series Shoc-Krome corrosion-resistant finish, oversized set screws, deep wire recesses, and daisy-chain design.
The Stinger SPD511 is the 4 gauge version of the PRO Series T-distribution block, providing three 4GA ports in a compact T-block form factor. Like the 8GA SPD510, it can be used to split one input into two outputs or daisy-chained for more complex multi-block configurations but handles higher-powered 4GA wiring suited to amplifiers up to approximately 1,500W.
Oversized set screws ensure maximum contact and vibration-resistant termination, while deep wire recesses eliminate exposed wire for a safe, professional finish.

What is the difference between the SPD511 and the SPD510?
Both are PRO Series T-distribution blocks with the same Shoc-Krome finish, set screw design, and daisy-chain capability. The SPD511 is 4GA and the SPD510 is 8GA. Choose based on the wire gauge used in your installation — 4GA for higher-powered amplifier builds, 8GA for lower-powered setups.
Can the SPD511 be daisy-chained?
Yes. Multiple SPD511 blocks can be linked together to expand distribution points for larger builds.
Is this block fused?
No. The SPD511 is a non-fused T-distribution block. Fusing must be provided externally on the main power run if using this for power distribution.
What gauge wire is compatible with the SPD511?
The SPD511 is rated for 4GA (4 AWG) wire on all three ports. For 8GA wiring, use the SPD510. For 0GA or larger builds requiring fusing, see the Stinger HPM Series distribution blocks.
Can this be used for both power and ground?
Yes. The SPD511 can be used on either the positive power or negative ground side of the installation.
