A spring plus serrated grooves that grip the lip of the channel provide a more secure hold than standard strut channel nuts.

In addition to serrated grooves for gripping the lip of the channel, these nuts have wings for easy positioning.

When there's no access to the open side of a strut channel, slip one of these nuts through a slotted hole and turn it 90° to secure it in the channel.

A tab fits tightly against the lip of the channel to keep these nuts from slipping.

Push these nuts into place rather than threading them onto a fastener.
