Aircraft on Jacks

Aircraft on Jacks – Do Not Enter Sign

Clearly establish a restricted safety perimeter around elevated aircraft with the Aircraft on Jacks – Do Not Enter Sign. Its bold ANSI-style DANGER header, dual warning symbols, and highly visible message help prevent unauthorized entry into areas where aircraft instability, shifting loads, falling components, or maintenance activity may present a serious hazard.

Precision CNC-machined from premium ¼-inch HDPE ColorCore, every letter, symbol, and border is engraved to a depth of 0.098 inches, permanently exposing the contrasting white core beneath the red surface. Unlike printed graphics or applied vinyl, the recessed message will never peel, crack, or require repainting.

Available in two landscape sizes:

• 10"H × 14"W
• 14"H × 18"W

The nonporous HDPE construction resists moisture, common chemicals, corrosion, and everyday industrial wear. Pre-drilled corner mounting holes provide fast, secure installation in maintenance hangars, aircraft assembly facilities, repair stations, inspection areas, military aviation facilities, and other demanding environments.

Manufactured in the USA with American material.
