SUPROJDM battery terminal blocks pair — 4-point flat-lug 6061 aluminum with stainless-steel bolts, compact low-profile

These SUPROJDM terminal blocks are a pair of 4-point flat-lug battery connectors made from 6061 aluminum and secured with stainless steel bolts for reliable electrical connections.

Designed for battery systems that use threaded studs or bolts, this pair of terminal blocks gives you four flat lugs per block for multiple cable terminations or accessory feeds. Each block is machined from corrosion-resistant 6061 aluminum and fastened with eight stainless steel bolts to resist rust and maintain good conductivity under vibration and outdoor conditions. The compact footprint—4.75 inches long, 2.5 inches wide and 0.45 inches tall—fits tight battery trays and small enclosures while offering clear mounting and wiring options.

How do these terminal blocks attach to my battery?

Each block is designed to clamp onto batteries that have threaded studs or bolts, using stainless steel hardware to secure the lug assembly. The flat lugs accept ring or fork terminals and can be stacked or used individually for neat cable routing.

• Fits batteries with threaded studs or bolts (standard stud spacing tolerated).
• Four flat-lug connection points per block for multiple conductors.
• Secured with eight stainless steel bolts—four per block—for vibration resistance.

What are the physical dimensions and material details?

The blocks are CNC-machined from 6061 aluminum for a good balance of strength, weight and corrosion resistance. The overall size makes them suitable for small to medium battery banks and confined installations.

• Body material: 6061 aluminum for mechanical strength and light weight.
• Bolt material: stainless steel to prevent rust and maintain clamping force.
• Dimensions: 4.75" length × 2.5" width × 0.45" height for compact mounting.

Can I use these blocks for multiple circuits or accessories?

Yes. The four flat lugs allow organizing several feeds—such as chargers, inverters, or accessory wiring—on a single terminal block while keeping connections accessible. Proper torque and correct terminal sizes are recommended to ensure electrical safety.

• Supports multiple conductors with separate lug points to reduce clutter.
• Ideal for creating grouped positive or negative bus points in battery banks.
• Use correct ring/fork terminal sizes and apply proper torque to bolts.

Who is this for: This product is aimed at DIYers, marine and RV installers, small off-grid system builders, and automotive technicians who need a compact, durable way to manage multiple battery connections. If you require corrosion-resistant hardware, a low-profile footprint and clear, organized wiring points on batteries with threaded studs or bolts, these SUPROJDM terminal blocks provide a straightforward mechanical and electrical solution. For safety, always disconnect power before working on battery terminals, use insulated tools where appropriate, and follow battery manufacturer torque recommendations when assembling connections.
