G'day Adam,

Generally, mesh flooring/footprint is the same thing, regardless of brand or compatible product, so it just comes down to size suitability.
As long as you're happy with the 240 x 240 size there's no reason why you can't use it with an RS-1 swag.
Just make sure your orientation stays in line so you don't end up with loads of peg holes.

G'day Trevor, 

Oztrail don't make a mesh floor specifically for their gazeboes like they do with the Oztent Screen House Mesh Floor but I can suggest the 10 x 10 ft Oztrail Ultramesh Tarp. It'll be within 5cm of the floor space of the gazebo you've got.

G'day Jerry, 

Bad news I'm sorry. I've just got off the phone to Oztent and they confirmed with me that they only make Screen House Mesh Floor for the square Screen House only. If you did buy the square mesh floor, it would be too small for your Oztent Screen House Hex.

G'day Judith, 

I'm not too sure what you mean, I've just double checked the dimensions and both the Oztent Screen House and compatible Mesh Floor are 240L x 240W cm.
