Black Sentinel Back Lake Barge — 8×20×4 flat-deck sectional steel hull with white interlocking coupler pins, sized for trucking without permits

Variant · Back Lake Barge

Back Lake.
No permits required.

The Back Lake is the Standard Barge architecture scaled to 8 ft wide and 4 ft deep. That narrower footprint lets two sections stack on a single flatbed truck with no oversize permit — and makes the barge compatible with truck, rail, ship, or air-freight handling to get you into remote sites where wide loads can't go.

Back Lake Barge FAQ

Pricing, specs, lead times, and delivery — straight answers.

Why is the Back Lake Barge 8 feet wide?+
8 ft is the maximum width that ships on a standard flatbed truck without an oversize-load permit in most Canadian and US jurisdictions. That means faster, cheaper, more flexible mobilization to remote sites.
Can I stack Back Lake Barges on a truck?+
Yes — they stack two-high on a flatbed, so a single truck delivers two sections in one load. This is the fastest way to get barge capacity into a back-country job site.
Are Back Lake Barges coupler-compatible with Standard Barges?+
No — the Back Lake series uses a narrower 8 ft width, so they couple to other Back Lake sections only. They share the same interlocking coupler engineering principles.
