FRONTLINE 18 Mortar Rack Frame - Fits 1.91" HDPE DR11 Tubes - (FRAME ONLY) by American Mortar Company

RONTLINE 18 — FRAME-ONLY PRO SERIES

ENGINEERED SPACING. MID-SIZE POWER. (TUBES NOT INCLUDED)

The FRONTLINE 18 is our most versatile mid-capacity mortar rack, now available in a Frame-Only configuration for pyrotechnicians who already own their own tubes and demand a superior, safety-engineered housing.

Designed for builders who want significant firepower without the footprint of a full box, this rack is built in a stable 3x6 straight formation. The FRONTLINE 18 is the ideal modular backbone for main show sequences, straight volleys, and professional choreographed displays where balance and control are required.

🛡️ THE ENGINEERED ADVANTAGE

Like all our premium units, the FRONTLINE 18 frame features Engineered Safety Spacing. We provide critical air gaps between every tube slot to ensure maximum thermal isolation and structural integrity. This allows for superior heat management during rapid-fire sequences—a feature standard "taped together" or "tight-packed" racks simply cannot match.
