Blue Sea Systems MaxiBus Insulating Cover, For 2127 and 2128

Overview

The Blue Sea Systems 2719 is an insulating cover for Blue Sea Systems 2127 and 2128 MaxiBus busbars. It snaps over the busbar to cover exposed connection points, which helps reduce accidental contact around high-current DC distribution areas on board.

It fits the 2127 MaxiBus 250A busbar with four 5/16-18 studs and the 2128 MaxiBus 250A busbar with two 5/16-18 studs plus six #10-24 screw terminals. Side breakouts let cables exit while the busbar stays covered, and the cover meets ABYC insulation requirements.

Key features

• Made specifically for Blue Sea Systems 2127 and 2128 MaxiBus busbars
• Snap-on insulating cover that shields exposed terminals and connection hardware
• Side breakouts allow cable runs to exit while the busbar remains covered
• Meets ABYC insulation requirements
• Matches the 2127 four-stud layout and the 2128 stud-and-screw layout
• Useful where a MaxiBus is mounted near batteries, behind panels, or in other areas where exposed connections need added insulation

Compatibility and fit

This cover is a fit-specific accessory for the Blue Sea Systems 2127 and 2128 MaxiBus range, not a universal busbar cover. That makes it the right part when your system already uses one of those MaxiBus layouts and you want the protection to match the terminal pattern correctly.

On a boat, that usually matters most in battery compartments, distribution spaces, and other service areas where tools, loose gear, or routine maintenance can bring something close to live bus connections. The cover adds insulation without changing the underlying busbar layout.

Installation and setup

The 2719 is meant to be fitted over the completed busbar assembly once the conductors and terminals are in place. The side breakouts give the cables a defined exit path, so the cover can sit properly without forcing an awkward cable bend at the busbar.

It is a straightforward finishing piece for installations that use a MaxiBus as a central DC connection point and want the exposed hardware covered while keeping the system serviceable.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
