Kong's history began in 1830 when Giuseppe Bonaiti opened the Bonaiti workshop on Lake Como in Lecco, Italy using with an engineering apparatus that was unusual for those times. That plant started producing Bonaiti carabiners in the early 1900s, establishing the Banaiti name in the climbing community. More climbing gear soon followed.
The Bonaiti company reorganized in 1977, adopted the name KONG, moved to the new factory of Monte Marenzo, and installed new machinery. In 1982 the company registered the name and trademark Kong in various countries. Kong continued to include the name Bonaiti on its products for many years.
The company is now managed by a sixth generation Bonaiti. Most Kong products are manufactured inside the Kong factory in Italy. Kong continues to produce carabiners and other tools used for safety in climbing, rescue, caving, yachting and work at height.
