Fiberglass Construction

Fiberglass mortar tubes are widely used throughout the fireworks industry because they combine strength, manageable weight, and durability. The fiberglass construction also behaves differently from rigid metal materials in the event of certain catastrophic malfunctions, helping reduce the risk associated with sharp metal fragmentation.

At approximately 3 pounds, this 4" tube offers professional crews a manageable option when transporting and assembling multiple mortars for a display.

Great for Custom Mortar Racks

This individual 4" fiberglass mortar tube is a convenient option for display operators who need replacement tubes or are assembling appropriately engineered mortar rack systems.

Its 22-inch overall length and 20-inch internal depth provide a compact professional configuration while allowing crews to incorporate multiple matching tubes into their display equipment.

Important Safety Information

This mortar tube is intended for properly sized 4-inch aerial shells only. Never use an undersized shell in an oversized mortar. Improper shell-to-mortar fit can create extremely hazardous firing conditions.

Mortar tubes must be properly inspected, supported, secured, and positioned according to applicable professional fireworks procedures before use. Never use a damaged, cracked, compromised, or improperly secured mortar.

Professional display fireworks should only be handled and discharged by appropriately trained and authorized personnel in accordance with all applicable federal, state, and local laws, permits, regulations, and safety requirements.
