FAA Infinity Gapless Letter & Number Stencil – 144″ | AC 150/5340-1M §1.3.9

FAA Advisory Circular AC 150/5340-1M, Paragraph 1.3.9 prohibits gaps in airfield character inscriptions — the small bridges an ordinary stencil needs to hold its letterforms together. That requirement can be enforced at any inspection, whether or not it’s been flagged in advance, so a standard bridged stencil carries real compliance risk that a gap-free design simply removes. It’s also why crews using a bridged stencil typically go back in by hand afterward to fill those gaps — extra labor, and a touch-up that’s only as clean and consistent as whoever’s holding the brush that day.

Our Infinity stencils solve the gap problem with a bridgeless, single-pass design, cut from proprietary orthopedic-grade LDPE, so every 12 ft character sprays as one clean shape with no post-paint touch-up — no hand-filling required.

We recommend Infinity as the default choice for every taxiway and apron letter: it satisfies the no-gap rule outright, so there’s no need to gauge in advance how strictly a given inspecting authority will enforce it. The standard bridged 144″ Letter & Number Stencil remains available, but Infinity is the safer buy whenever gap-free compliance matters.
