The basic drain auger (coil and auger head) is the main working part of every type of drain snake.
Closet auger tube
The snake retracts into the the tube before use, which makes it easier to insert the auger into the blocked toilet. There is also an inner tube that allows the retraction and dispensation of the snake.
It is operated by the handles, which pull or push the inner tube, and subsequently the snake, into position.
Closet auger bowl guard
The bowl guard is a curved section at the base of the tube, covered in vinyl. It both guides the auger around the bend, at the base of the toilet bowl, and protects the porcelain from the metal snake.
Extra features available for closet augers
Clip
There is a clip at the base of the handle to secure and store the snake when not in use.
Extending button
There is a button at the top of the inner tube on 6ft toilet augers. This releases the extra length of snake when required.
