Overview

The Blue Sea Systems 2709 is a snap-on cover for the Blue Sea Systems 2701 DualBus 100A bus bar. It measures 4-3/16 in. long, 7/8 in. high, and 2-1/2 in. wide, so it matches the 2701 footprint and adds a protective layer over the terminal area without taking up much extra space.

This cover leaves wire access open while helping reduce accidental contact with the terminal studs. On boats where the bus bar sits behind a helm, inside an electrical locker, or under a console, that extra protection is useful during wiring, inspection, and routine service.

The housing is polycarbonate and the piece weighs about 0.03 lb, so it is easy to handle during installation. This is a fit-specific accessory rather than a universal cover, and the key compatibility point is the Blue Sea Systems 2701 DualBus.

Compatibility and fit

Use this cover when your distribution point is a Blue Sea Systems 2701 DualBus. It is not a general bus bar shield for other stud layouts or terminal counts. In refit work, that matters because the 2701 combines positive and negative buses on one block, and this cover follows that specific layout.

Installation and setup

The cover snaps onto the terminal studs after the bus bar has been mounted and wired. Leave enough clearance above the bus bar for the cover height and for the wire bend coming off the terminals. That keeps the cover seated properly and makes later inspection easier.

Use on board

This part makes sense on boats that use a compact distribution point in a console, cabin locker, electronics space, or other protected electrical area where hands and tools may come close to the bus bar during service. It is a good match for owners and installers who want a neater finish around the 2701 and more separation around exposed terminals without changing the bus layout itself.
