Figure 16: 2 ft × 4 ft (610 mm × 1220 mm) hood and frame. The support poles always cross as
pairs at the front and back of the fabric hood. For the 2 ft
× 4 ft (610 mm × 1220 mm), the support
poles are inserted into the inside ferrule locations.
The number 1 and 5 channels also have a wing nut at the straight end which will mate with an angle and
studs on the ends of numbers 2, 5 and 6 to form the longer frame sides (see Figure 20).
