A periscope for a tank and safety glass for a construction vehicle are widely different products. They have two things in common, however: They are designed to protect human lives, and both are manufactured by GuS PRÄZISION IN KUNSTSTOFF, GLAS und OPTIK GmbH & Co. KG – or GuS Glass + Safety for short. The medium-sized family enterprise is a hidden champion committed to delivering the highest quality for military and civilian missions.
