RAMPART 18 Straight 18-Shot Mortar Rack - 1.91" HDPE DR11 Tubes

VERTICAL PRECISION. ENGINEERED SPACING. PROFESSIONAL BUILD.

The RAMPART 18 STRAIGHT is a purpose-built 18-shot mortar rack designed for pyrotechnicians who value tight volleys, precise timing, and clean vertical symmetry. Built with two disciplined rows of nine tubes, this rack is engineered to stack the sky—delivering powerful, straight-up shots ideal for synchronized firing and layered height effects.

Like all our premium units, the RAMPART 18 features Engineered Safety Spacing—providing critical air gaps between every tube to ensure maximum thermal isolation and structural integrity, even during high-volume vertical breaks.

Disciplined, structured, and built to last—this is where serious setups begin.

🛡️ THE GOLD STANDARD: WHY HDPE DR11?

In the world of pro pyrotechnics, the material of your mortar tube is the difference between a successful show and a dangerous failure.

• Shatter-Proof Safety: Unlike PVC, which can shrapnel into sharp plastic shards during a shell failure, our High-Density Polyethylene (HDPE) is designed to swell or tear under extreme pressure, significantly reducing the risk of flying debris.
• DR11 Heavy Wall: We use the DR11 specification, providing a thick, durable sidewall that handles the high-pressure lift charges of modern 1.91" canister shells with ease.
• Signature Patriot Blue: Our signature blue tubes are UV-stabilized and weather-resistant, built for hundreds of reloads without becoming brittle.

🔵 COMMERCIAL-GRADE CONSTRUCTION

Each RAMPART 18 rack includes 18 premium HDPE DR11 mortar tubes, built to professional specifications and trusted by experienced shooters.

• Inner Diameter: 1.91″ (Fits most consumer canister shells)
• Length: 12″ (Professional mortar standard)
• Bottoms: Factory-plugged and Quad-Stapled (4-point reinforcement) for maximum lift retention.
• Stability: Wide-stance, low-profile, tip-resistant design built from reinforced lumber.
