Square, smooth design insures a better fitting cover. These galvanized fittings are used to join front bars with end rafters but they are ideal for making right angles in any frame assembly.
There is a round head machine screw at the corner which can be used to hold a grommet in the fabric cover insuring a neat, finished appearance along the front bar.
The slip fit attachment permits a 1/2-inch adjustment in the frame. For use with 3/4" galvanized pipe.
Note: 3/4" Galvanized pipe is 1" outer diameter.
