Match the tube to the shell
The single most important rule: the mortar tube caliber must match the shell it fires. A shell that is too small for the tube can shift or tilt, sending the effect off-axis; the tube's internal diameter is what defines the shell size it is designed to launch.
Our fiberglass tubes come in a full bore range — 2, 2.5, 3, 4, 5, 6, 8, 10 and 12 inch — so a display company can stock the exact calibers its shows require rather than compromising with mismatched sizes.
Why fiberglass for professional work
Fiberglass tubes hit the professional sweet spot: strong enough to withstand repeated firing, yet light enough to rack, carry and reposition quickly on a field. That strength-to-weight balance is why display crews favor fiberglass for touring shows.
Fiberglass also lasts across many seasons, making it a durable-goods investment rather than a per-show consumable. Custom color and logo options let display firms brand their field hardware.
Pairing tubes with the right rack
Tubes need racks to hold firing angle and geometry. For single-shot arrays of Roman candles and small calibers, a lightweight aluminum rack sets up fast and carries easily. For heavy mortars and high-volume firing, a rigid steel rack provides the stability to hold angle under recoil.
The right combination depends on the show: light aluminum for speed and portability, steel for heavy-calibre stability. Many crews carry both and match the rack to each job.
Source tubes, racks and igniters together
Tubes, racks, igniters and firing systems all work as one kit. Sourcing them from a single manufacturer guarantees compatible sizing and simplifies reordering across a display operation.
As a factory producing fiberglass mortar tubes, aluminum and steel racks, igniters and firing systems, we help display companies assemble a complete, correctly-matched firing setup at wholesale pricing with custom branding.
