Strut Channel Nuts
What is a channel nut?
Channel nuts twist into position inside of strut channel to provide secure placement of fittings and other strut-attached hardware. They are made of carbon or stainless steel and have serrated indentations on two sides that fit underneath the down turned lips of the channel. These serrated indentations bite into the channel to prevent slipping. Once engaged with a bolt, channel nuts will rotate 90° and lock into place for alignment and secure positioning.
