There are various types of Side Curtain Fitting each designed to undertake a different operation. GTF stock a flat snap hook, a three-bar slider and a wire formed rave hook. The rave hooks are used either on the curtain side for tensioning the side curtain. The rave hooks, snap hooks and three-bar slider are used in the production of internal vertical straps. The Three-Bar Slider is used to adjust the webbing and the snap hook is used to connect onto a round ring that runs down the centre pole the full length of the vehicle.
