These clips can be used to speed up set changes by avoiding the need to bolt up folding gate rostra. They clip neatly around 3" x 1" (75x25mm) or 3" x 1 ¼" (75x32mm) PAR timber. They can also be used to secure rostra with fixed tops when the lack of access to the underside prevents bolts from being used. The finish is black powder coated.
