How to choose SIXTOL crossbars SX1016, SX1018 and SX1019 (and how to tell roof rails vs. fix points)

10. 01. 2026

You want to put a roof box, bikes or skis on the roof – but you’re not sure which attachment type your car has? Choosing SIXTOL crossbars is simple: the roof type decides – raised roof rails, integrated rails or fix points. In this article we’ll show you how to recognize it in one minute and which model to choose.

Quick choice by roof type

SX1016 – for classic raised roof rails (there’s a gap between the rail and the roof).
SX1018 – for integrated/flush roof rails (the rail sits directly on the roof, no gap).
SX1019 – for fix points (the car has no roof rails but has mounting points in the roof under covers).

1) Classic raised roof rails – choose SX1016

You can recognize classic raised rails because they are on 'legs' – there is a visible gap between the rail and the roof. Often you can easily slide your fingers under them.

Typical sign: a gap under the rail (the rail is not flush with the roof).

Use: roof box, bike carrier, skis, other T-slot accessories (T-bolt).

Right choice: SIXTOL ROOF RACK – code SX1016 (120 cm, max load 90 kg).

2) Integrated (flush) roof rails – choose SX1018

Integrated/flush rails sit directly on the roof – without a gap. They are typical for newer estates and SUVs. If the rail is 'joined' to the roof, this is the type.

Typical sign: no gap between the rail and the roof.

Important: measure the spacing where the feet will clamp (both front and rear positions).

According to customer queries the maximum spacing of the feet when set in the extreme position is approximately 115 cm.

Right choice: SIXTOL ROOF RACK IN 1 – code SX1018 (120 cm, max load 90 kg).

3) Fix points – choose SX1019

If the car has no roof rails it may have so-called fix points (pre-prepared mounting points in the roof). You can recognize them by the covers/plugs on the roof – after removing them you’ll find mounting holes (typically 4 points).

Typical sign: there are caps/plugs on the roof; under them are mounting holes for attachment.

For vans larger spacings are sometimes required – in some vehicles longer crossbars are used (e.g. 135 cm).

Right choice: SIXTOL ROOF RACK FIX 1 – code SX1019 (120 cm, max load 90 kg).

Quick comparison SX1016 vs. SX1018 vs. SX1019

Model	Attachment	Length	Max. load	T-slot	Lock
SX1016	For raised longitudinal rails	120 cm	90 kg	20 mm	Yes
SX1018	For integrated/flush rails	120 cm	90 kg	20 mm	Yes (2 keys)
SX1019	For fix points	120 cm	90 kg	20 mm	Yes (2 keys)

Check 3 things before buying

Roof type (gap under raised rails vs. integrated rail vs. fix points under covers).
Spacing at the attachment points (for the chosen type – ideally measure front and rear positions).
Maximum allowed roof load of your car (set by the vehicle manufacturer; always observe the lower limit).

Most common customer questions

"I have a new SUV and I don’t know if the rails are integrated."
Look for the gap: gap = classic raised rails (SX1016). No gap = integrated rails (SX1018).

"The same car model comes with different roof versions – what now?"
Don’t rely only on the model year. Check the roof and re-measure the spacing at the attachment points.

"How do I recognize fix points?"
Look for plugs/covers on the roof. After removing them you’ll see mounting holes (usually 4 points).

Summary: which model is for you?

Gap under the rail → SX1016
No gap (integrated/flush rails) → SX1018
No rails, but mounting points under covers → SX1019
