The 300 TE is the largest model in the pitched-roof TE series. With a floor area of 300 × 200 cm and a ridge height of 200 cm, it offers the largest coverage area in the TE series—making it suitable for extensive maintenance work, large excavation pits, and as weather protection for several people at once. Despite its size, the 300 TE weighs only 22 kg and can be set up by one person in seconds. The translucent tent fabric, which does not distort colors, is optimized for electrical and cabling work.
