attached to the square tube end caps which will keep the rainfly fabric taut in order to keep the rainfly support rods in the proper location a series of loops which are sewn welded or heat seamed are added to the underside of the rainfly at the highest point so that the fiberglass rods can be inserted into the loop directly above the square support tubes once this has been done for each of the fiberglass rods each rod can then be inserted into the rainfly support receivers on the rainfly support square tube on either end the rainfly can then be centered over the arched rods and attached to the square tubes fig1 depicts and alternative design where instead of specialized caps the flexible rods are inserted into holes further to increase the flexibility of the rods in rolling flexible rod connectors can be included so that each rod comprises two connected shorter rods spanning the rain fly the rainfly should now be attached to the square tube s using 8 u00d7 u00bc u2033 phillips truss head stainless steel screws starting at the middle of the cover the rainfly fabric will be centered from side to side on top of the fiberglass support rods and fastened onto one of the center square tube s with a u215cth u2033 stainless steel washer to help spread out the pressure of the screw on a larger area of fabric now on the opposite end of the same center square tube the fabric will be pulled taut and fastened to the support with a.
