This easy to use fittings class comes with "threaded eye bolt" which can be tightened after the pipe or tube is inserted for tight fit connection. The whole canopy can be put together easily using indicated fittings for different connection and tightening the eye bolts. Eye bolts can easily be unscrewed for dismentling for future use.
