If you want to couple together two 7 x 7 m PVC Party Tent Marquees to double the number of square meters, we recommend you to buy a rain gutter specifically designed for this purpose. The rain gutter is, like the Party Tent Marquee, made of strong PVC. Easy assembly between the two Party Tent Marquees on the back side of the frieze of the roof cover. The size and width of the rain gutter ensures that rainwater is drained off effectively.
