Fused distribution block from Tsunami. Finishes your installation. Fuses not included (choose the amperage fuse that suits your install). Usually used to fuse amps in the back or other components. CNC machined in one piece, high quality products (usually with covers). Machining in one pieces means more contact area, highest current capability and lowest resistance by eliminating the traditional weak separate spring clips and screws that can rob power from your system.Products with LOKNUT compression (see title) lock cables into place with TITANIUM CNC hardware in 24k gold.Ultra clear insulating covers with recessed logo badge desins are the perfect finishing touch.
