RIDGID sink machines — the K-39, K-40, K-45, and K-50 series for clearing kitchen, lavatory, and small drain lines from 3/4" through 2-1/2".
The K-40 and K-45 are the most-stocked sink machines on plumbing service trucks for one reason: they handle 95% of residential kitchen and bathroom callouts. AUTOFEED variants advance and retract cable without the operator gripping it. The replaceable inner drum and clutch make these machines outlast cheaper imports many times over.
