How to Fit a Gas Strut 

The offset is different for every set up, but the principle is the same. It needs to be set so when the door is closed the top point is slightly behind the bottom point. This means when closed the gas strut is putting a slight pressure against the door and seal. If this offset is too much the door will be hard to open. If the top point is not behind the bottom point the door will not shut properly as the gas strut will always be forcing it open.

Hello! While we don't design the frame of the vehicle, we specialize in providing essential hardware components like hinges and gas struts. If you have any specific requirements or need assistance with these parts, we'd be happy to help!

Yes it is possible if you have strong enough gas struts, however a linear actuator would be better given the weight.

you can use 2 gas spring for a door

Thanks for your feedback and sorry that our instructions were not clear enough. The P and S dimensions are dependent on many factors, including the size of the gas strut, the stroke length of the gas strut, size of your door and required opening position. For a rough guide of the P dimension you can match the size of your gas strut to the closest one in our range and find the P dimension in the graph: www.comac.co.nz/modules/SP_webshop/products.php?cat=1546?

Thank you for your feedback TinyHouse! As you would have seen this video details how to fit a gas strut, not how to choose a gas strut. While we cannot know the weight of every single customers door, our gas struts come supplied with 40kg - 250kg of pressure (depending on the size of the strut) and are adjustable which allows them to be calibrated to suit the weight of the door.

Hi Smuzz thank you for your feedback. This is an older video, please see our updated one which we hope will make it clearer for you. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0YtST0dPueA.html The video explains how to find the gas strut you need based off the width of your door. Once you have the gas strut length find the closest extended length in the chart at 55 seconds and use the matching P Dimension. The P dimension is the distance between the hinge and the top mounting point of the gas strut when the door is open to 90°

Thanks for your feedback Allan, we are working on an updated video. How could we make it clearer for you?

Hi Robert, as a NZ supplier we operate using the metric system but we understand that not everyone in the world is the same. For a simple conversion from mm to in divide the length value by 25.4. Thanks

@@co-macgroup1683 Thank you.

@@co-macgroup1683 Nearly the whole world is metric. Exceptions: USA and a few small affiliated jurisdictions.

what problem to buy two scale tape ?!

I also had to stop watching after 10 seconds because i am also a retard.
