mocomax 35-Inch Smokeless Octagonal Fire Pit Ring — 31in Inner, Heavy-Gauge Steel

The mocomax 35-inch smokeless octagonal fire pit ring is a heavy-gauge steel liner designed to create cleaner, hotter, and longer-lasting wood fires for above-ground or in-ground outdoor use.

Built for backyard evenings, campsite gatherings, and DIY fire-ring installations, this octagonal fire pit liner combines improved airflow, a high-temperature coating, and a distinctive shape to encourage steady flames while reducing smoke. The ring measures 35 inches across the outer edge, with a 31-inch inner opening and 8.5 inches tall walls—large enough for family-sized wood loads yet compact enough for patios, decks with proper clearance, or recessed fire pits.

How does the octagonal shape affect flame performance?

The eight-sided form is more than aesthetic: the flat panels and angled joints help channel air around burning logs and stabilize the stack of wood. That steady geometry promotes even combustion and complements the drilled ventilation holes for a more complete burn.

• Octagonal walls create stable log placement and airflow paths
• Flat panels reduce unpredictable drafts compared to thin wire rings
• Designed to work with ventilation holes for hotter, cleaner fires

Will this fire pit really reduce smoke and improve burn efficiency?

This fire pit ring incorporates multiple ventilation holes drilled around the body to introduce oxygen beneath and around the fuel, which helps wood reach higher temperatures and burn with less visible smoke. While no outdoor wood fire can be entirely smoke-free, improved airflow reduces wisps and increases combustion efficiency.

• Perforations encourage oxygen flow for hotter flames
• Higher temperature coating tolerates intense heat without degrading quickly
• Better combustion means less partially burned material that causes smoke

Is the mocomax liner durable and safe for regular outdoor use?

Constructed from thick steel with a high-temperature finish, this liner withstands very high temperatures and repeated heating cycles. It’s built as a long-lasting pit component rather than a thin, temporary ring—still follow local fire-safety rules and maintain proper clearances from structures and combustible materials.

• Heavy-gauge steel resists warping under heat
• High-temp coating rated for extremely high temperatures
• Designed for both above-ground placement and in-ground installations

How easy is assembly and what are the dimensions I should plan for?

Assembly is straightforward and meant to be completed in minutes with the included instructions and basic hand tools. The unit stands 8.5 inches tall with a 31-inch inside diameter and a 35-inch outer diameter—measure your intended location and provide safe clearance for sparks and seating.

• Quick bolt-together assembly with supplied hardware
• 8.5" wall height for larger wood stacks and containment
• 31" inner diameter fits standard split logs and fire layouts

Who is this for: the mocomax 35" Smokeless Octagonal Fire Pit Ring suits homeowners and outdoor enthusiasts who want a robust, reusable fire liner that improves airflow and looks distinctive. It’s aimed at DIY builders finishing a recessed pit, patio users who prefer a contained ring, and campers or hosts seeking a dependable steel liner for repeated backyard fires. Always use on a non-combustible surface, follow local regulations, and operate with responsible fire safety practices.
