The Kupo 6" Pump Suction Cup with 5/8" Baby Pin is a useful accessory for mounting lights, cameras, and grip gear on smooth, non-porous surfaces. It provides secure temporary support when stands are not available. The cup is made of rubber material with silicon and can withstand temperatures ranging from 10.4 to 120 degrees Fahrenheit. Notably, this version features a metal piston, an improvement over the plastic one in earlier models.
