Hook-wall packer Definition


Hook-wall packer:

A packer equipped with friction blocks or drag springs and slips and designed so that rotation of the pipe unlatches the slips.

The friction springs prevent the slips from turning with the pipe and assist in advancing the slips up a tapered sleeve to engage the wail of the outside pipe as weight is put on the packer.

Also called a wall-hook packer.

See packer.
