Overview

The Blue Sea Systems 2708 is a busbar cover sized for the Blue Sea Systems PowerBar 2104. It measures 8.500 x 3.375 x 2.750 inches and fits over the 2104 busbar to put a physical barrier over the connection area while keeping the assembly compact.

On a boat, this is the kind of part that helps around exposed high-current distribution points where battery cables, service tools, and nearby hardware can end up close to live studs. It is matched to the 2104 PowerBar, which uses four 3/8-16 studs and is commonly installed in heavy DC distribution runs.

Key features

• Exact fit for the Blue Sea Systems PowerBar 2104
• Covers the busbar connection area to reduce accidental contact with energized studs and attached cable lugs
• 8.500 x 3.375 x 2.750 inch overall size helps you check clearance before closing up a battery or distribution space
• Low 0.10 lb weight adds protection without adding meaningful load to the installation

Compatibility and fit

This cover is specific to the PowerBar 2104 and should be treated as a model-specific part rather than a universal busbar cover. For replacement work, the main checkpoint is the base busbar model.

It suits installations where the 2104 remains accessible after wiring is complete, such as battery banks, inverter feeds, charging circuits, and other high-amperage DC distribution points.

Installation and setup

The cover is easiest to add once cable routing, lug placement, and final torque checks are already finished. Before closing the busbar, confirm that the mounting area has enough room for the 2.750 inch height and the full cover footprint.

This part makes the most sense for installers and boat owners who want cleaner protection around an exposed 2104 busbar in spaces that may be reached during routine service or electrical work.
