The Inhaker is a post system in which the sign hooks onto the post rather than being screwed to it. This allows you to replace the sign whilst the structure remains in place.
This is intended for a venue where the message changes whilst the event is underway: a course that points in a different direction after the first lap, a programme that varies from day to day, or a sponsor who is only involved for part of the weekend. Anyone who tries to do that with fixed signs will find themselves standing by the roadside with a screwdriver every single time.
The system It consists of the posts and the signs sold separately, so you buy the posts once and the signs as many times as you need. If you’re looking for signs that are meant to stay in place, then you’ll find them at the signs out.
