Choosing the right drive-away awning starts with one measurement: the height of your van's kador rail from the ground. Get this right and the awning will connect cleanly and perform well. Get it wrong and it won't fit at all. This guide explains exactly how to measure up and which profile you need for the most popular campervans in the UK.
Step 1 — Find Your Kador Rail
A kador rail (also called a kador channel or awning rail) is a C-shaped aluminium channel fitted to the side of your campervan. Drive-away awnings connect to it via a kador bead or sleeve that slides into the channel.
On most professional campervan conversions, the kador rail runs along the roofline on one side of the van. If your conversion doesn't have one, you can fit a pole & clamp attachment as an alternative — check your chosen awning's compatible attachment options.
Step 2 — Measure Your Kador Rail Height
Using a tape measure, measure the vertical distance from the ground to the bottom of your kador rail channel. Do this on a level surface with the van unladen. This is the number that determines which awning profile you need.
Step 3 — Match Your Measurement to an Awning Profile
Drive-away awnings come in three profile heights:
Low Profile — 180–210cm
For compact campervans with a kador rail height of 180–210cm. This covers the most popular compact van conversions in the UK:
- VW T5 & T6 (Transporter, California)
- Ford Transit Custom
- Vauxhall Vivaro
- Renault Trafic
- Mercedes Vito
- Nissan NV200 / NV300
→ See our best low-profile drive-away awnings guide
Mid Profile — 210–255cm
For large campervans on standard or medium roof variants with a kador rail height of 210–255cm:
- Mercedes Sprinter (standard/medium roof)
- VW Crafter (standard/medium roof)
- Fiat Ducato / Peugeot Boxer / Citroën Relay (standard roof)
- Ford Transit full size (standard/medium roof)
→ See our best mid-profile drive-away awnings guide
Tall Profile — 255cm+
For high-roof large vans with a kador rail height above 255cm:
- Mercedes Sprinter (high roof)
- VW Crafter (high roof)
- Fiat Ducato (high roof)
- Ford Transit full size (high roof)
If you have a high-roof van, contact us and we’ll help you find the right tall-profile awning.

Heights are typical conversion measurements. Always measure your own kador rail before ordering.
What If My Van Isn’t Listed?
If your van isn’t in the table above, measure your kador rail height and match it to the profile range. If you’re still unsure, contact us at Newquay Camping Shop and we’ll help you find the right awning.
Do I Need a Poled or Inflatable Awning?
Once you know your profile, the next decision is poled vs inflatable. In brief:
- Poled awnings — lower price, longer pitch time (20–40 mins), easier to repair in the field.
- Inflatable awnings — faster pitch (5–10 mins), easier solo setup, higher price.
For a detailed breakdown, see our Inflatable vs Poled Drive-Away Awnings guide.
Frequently Asked Questions
How do I measure my kador rail height?
Park on a level surface with the van unladen. Use a tape measure to measure from the ground to the bottom of the kador rail channel on the side of your van. That measurement tells you which profile awning you need.
What if my kador rail height is right on the boundary (e.g. 210cm)?
If your measurement is at the upper end of the low-profile range (around 205–210cm) or the lower end of the mid-profile range (210–215cm), check the specific awning’s stated connection height range before ordering. Some awnings have a small amount of adjustment. Contact us if you’re unsure — we’ll help you find the best fit.
What is a kador rail?
A kador rail (also called a kador channel or awning rail) is a C-shaped aluminium channel fitted to the roofline of a campervan. Drive-away awnings connect to it via a bead or sleeve. Most professional conversions include one; if yours doesn’t, a pole & clamp attachment kit is the alternative.
Can I fit a drive-away awning without a kador rail?
Yes — most drive-away awnings support alternative attachment methods including pole & clamp kits. Check your chosen awning’s compatibility before ordering, or contact us for advice.
Do drive-away awnings fit all vans?
Drive-away awnings are designed for campervans and van conversions with a side kador rail. They are not designed for cars, SUVs, or motorhomes without a suitable rail — although tailgate awnings are available for SUVs and estate cars.
