G'day Peter,

Not from us, but you may be able to get your hands on spare parts from Supex directly.
You can contact them here.

G'day Kym,

You would want 2 roof rafters for an annex of that size.

Generally you want to aim for a rafter that is curved enough to keep the canopy taught, but not so tight that it stretches the fabric too much.

The Supex Slight Curve Rafter which has an approximate curvature of 25-35mm, has a rounded profile to help protect your awning from wear against the rafter and would be a perfect option for newer awnings or those looking to add some support without stretching the fabric too much.

Older awnings that have already stretched and sagged over time would benefit from one of the larger curvatures like the the Supex Acute Curved Rafter which has a slightly larger curve of 65-75mm. This provides a bit more tension to the canopy for better protection against wind flap and water pooling.

G'day Gary,

These particular spreader bars are designed for caravan awnings which are a little different from your typical 4WD side awning, so you could possibly find a way to adapt these to fit, but it might not work. I guess you could try this, as it will likely be a cheaper option than a new awning.

G'day David,

The roof rafters are extendable - 243cm is the shortened length and 275cm is the maximum length they extend to.

G'day Tracy,

We find that most people will go for the Slight Curve as it will give you good tension without too much stretch on the awning.

G'day Jim,

Yep, it sure is!

G'day Corey,

I've just double checked and the Curved Roof Rafters only come in the white colour. 

Good news Corey!

We have just added the Slight Curve option in Black.

G'day Bob,

Thanks for your enquiry. I contacted our rep at Supex to confirm this answer for you. The MK3 version has been around for quite some time and is definitely the model we stock. I was advised you won't be able to find the MK2 model anywhere these days. The difference between the two is the inner pole now comes with 3 straight edges and a curved top so there are no sharp edges against your awning. 

G'day Keith,

I have contacted Supex who have confirmed the distance of each Curved Roof Rafter.

Slight- 25-35mm at a 2.4m extension

Acute- 65-75mm at a 2.4m extension 

This distance is from the centre point of the rafter to the ground when lying on the ground. I hope this makes sense. Please call our customer support team on 1300 914 007 if you need clarification. 

G'day Terry,

You're spot on, there are two models. We stock both and you can select the option you'd prefer using the drop-down menu just above the "add to bag" button.
