    Maybe replace the gas struts with stronger one’s. I’m going to replace mine with 500 nm strength. This is for a Gypsey Regal. Sourced from McNaughton’s in Pinetown.

    Hi

    What is the strength (KPA) needed to lift the pop up roof ?

    Will 10 KPA do the job or to strong?

    Hi, See my earlier comments. I think this depends on the size and weight of your roof. I have a Gypsey Regal and first tried 450nm which was to weak, I then took them back to McNaughtons and had them pumped to 500nm. I feel I could have gone to 550nm. But 500 is working fine. I hope this helps.

    Hi Jannie,

    This is a very old post but do you perhaps have the size you bought for your Regal. I also have a 2001 and need to replace the struts.

    Thanks

    I notice the force of the gas struts being quoted here in ‘nm’. This is incorrect. The force from gas struts is a linear or straight line force and is measured in Newtons.

    Nm is a rotational force or torque measured at the end of an imaginary 1 metre shaft set perpendicular to a rotating axle such as a crankshaft

    To find the gas strut force required to raise the roof you need to know the weight of the roof.

    Since there are 4 struts that will share the weight equally you can then divide the weight by 4.

    Since the struts will only rise to an angle of about 45 degrees you multiply this weight by 1.414 ( sin45).

    Since there are 9.8 Newtons required to lift a single kilogram you now multiply by 9.8.

    Since you need to build in a margin for under performing struts you now multiply by 1.2.

    Now you know what to get your struts pumped to in Newtons not nm.
