8 machine type screws about a number 10 X 1 3/4 no bigger if you must use the slot head screws there is one slightly smaller that will work just fine. 8 nuts to fit the above 16 washers to fit the above. I preferred the hex head screws as it is easier to get behind the frame with a wrench than using a screwdriver.

Cut the two 10' lengths of 1/2 inch pipes in half leaving you with four 5 foot lengths

Drill a 1/4" hole as close to the size of the screw as possible in each end of the PVC pipe in the exact same point on both ends.

Drill a hole in the frame of the canopy about 5 or 6 inches from the cross nut of the canopy frame on all sides of the frame. Do NOT make a hole any bigger than you have to in either the canopy frame or the PVC pipe. This means that you have two holes on all four sides of the canopy frame.

Now you put the screws in from the outside of the frame using one of the washers, but not the inside as this will push the canopy fabric and you don't want to stretch it there as it may tear the fabric. If you did it right, you'll have to screw the screw in otherwise you made either the hole in the canopy frame or the PVC pipe too big. Slide the PVC pipe onto the screw, then add the second washer and nut in this order. Do not over tighten, you just need it snug. You will see that the PVC pipe looks like a half circle. Then you physically move the pipe to the center of the tent so that the top is snug and has no place for water to rest. Now tighten the screws just until the PVC pipe barely starts to come together. Make sure your pipe looks up almost to the sky, not sideways. The above installing of the new hoop is easier to install when you put up your canopy if you raise the legs so that you are close to eye level to the holes and can still move the hoops skyward. Remember that it doesn't hurt to have the screws extra length
