      Replaced an old glass fuse panel that was large and rusty. This unit is much more compact that the old unit. This has an easy to remove cover and holds two spare fuses.

            Comments about ST Blade Fuse Blocks:

            I installed a 2003 model 5.3 liter Vortec engine in a classic truck and needed a fuse block for the computer, fuel pump, and sensors. I bought the Blue Sea fuse block (12 position), and I couldn't be more pleased. It is compact, well built, and easy to wire. I recommend it to anyone.

                Comments about ST Blade Fuse Blocks:

                I am a marine electrician and electronics installer. I use these on a regular basis since I often work on trilerable boats with mediocre distribution systems. They are easy for my customers to understand and use if a fuse blows. The fuses are easy to identify, unlike the glass vial SAE type.

                            This item was perfect to mount on boat
                            transom to consolidate all the electrical
                            needs of the boat; negates wear/tear corrosion
                            of all the wires on and off the battery terminals.
