Yes, the straps attach to the wodden bows, over the rolled up canvas to hold it in place. When you roll up sides , roll to inside. That way the rain doesn't collect in the folds. Also throw side ropes in before rolling. Back and front cab sections rope through eyes around the front and rear bow with straps attached. Front section goes over the rear pice and buckles in place. Good idea is to put front onto windscreen, buckle up to rear than pull rear section to get tension all the way through. I see the ubiqitous cable tie to hold bow to lazyback. Mine are bored through with a butterfly nut and coach bolt Worth putting stretchers acros sthe bows to fix them. I have thin plastic sheet, actually ex Bus advert boards under the canvas to stop water puddling.
