KB II Series 2-quart cups feature a "pistol grip" carrying handle, and right- or left-handed design for comfort and ease of handling. An easy-open lid and wide cup mouth allow for fast filling and cleanup. KB II Series cups also feature a solvent-resistant check valve, a 0-30 psi air gauge, and a wide base for greater stability. KB II Cups are supplied with disposable cup liners, which reduce clean-up and solvent use. The unique lid liner also protects the underside of the lid, preventing check valve problems.
