What you need to know about the 316mm Gas Strut
The Dunn & Watson 316mm gas strut is perfect for use in four-wheel-drives, utes, caravans, camper trailers, and RVs. If you have anything–from doors and boots to toolboxes and windows–that needs to open and close, these high quality 316mm gas struts are right for you. Made in Australia to our exacting standards and tested extensively, make sure you source your gas struts from Dunn & Watson exclusively!
What’s the weight capacity of the 316mm gas strut?
Gas strut weight capacity is measured by units of newton force (n). Our range of 430mm gas struts come in 100n, 200n, 300n, and 400n capacities. The weight capacity of the gas strut is related to this newton force, using the calculation of 10kg for every 100n.
A 400mm strut with a 300n rating has a weight capacity of 30kg. A 316kg x 100n gas strut has a capacity of 10kg. It’s essential you know the weight of the item that’s being opened and closed to find the right weight capacity for your gas strut.
If your application has weight that is closer to the hinges than normal, your weight capacity will need to increase. The above calculation is only for normal circumstances. If you’re not confident with what sort of 316mm gas struts you need, feel free to get in touch with us today.
How to select the right gas struts?
If you purchase a 316mm strut, it means that the full extension length of the gas strut is 216mm. The length needs to be about 60% of the height of the door or window that’s being opened and closed. This means that this particular gas strut is suitable for lifting doors or windows of length approximately 526mm (e.g. 316mm is 60% of 526mm). This calculation gives you the length; we’ll now go into how to work out the required newton force.
Replacing existing gas struts
If you are replacing an old gas strut because it’s no longer functioning properly, there’s often a label with all the information you need. If you don’t have access to this information, measure the diameter of the shaft and the cylinder. You then need to estimate the newton force needed. A handy way of doing this is by using a broomstick and bathroom scales. Keep in mind that 10kg equals 100n.
Once you have all these measurements, select the 316mm gas strut with the right newton force. Remember to bear in mind any custom weight increases to windows or doors when working out how much force you need. To break it down for you, if you’re purchasing a 316mm strut and the window or door or lid that is being lifted weighs 20kg, you need the 316mm x 200n gas strut.
Don’t forget to check the width of the shaft and cylinder of the replacement strut as well to make sure it matches.
Initial gas strut installations
Installing gas struts for the first time is a bit more complex. The formula for working out what you need is not as daunting as it might first appear. Just work out one measurement at a time and you’ll find it easy. If you would like help, we’re happy to lend you a hand.
The measurements required include:
G = the weight of the item to be lifted (door, lid or window)
H = 60% of the length of this item
L = mounting distance of the hinge
Using these numbers you can work out the newton force needed. Work out 60% of the length of the door or window to find the size of the strut: if the door is 515mm then 60% of that length is 309mm, so a 316mm strut will suffice. Once you know that the newton force is 300n then you know you need a 316mm x 300n strut.
Features of the 316mm gas struts from Dunn & Watson
We manufacture our own gas struts right here in Australia. So we know that the quality management is comprehensive and reliable. Think a 20,000 cycle testing regime and 150 hours of shaft salt exposure testing. These tests and standard checks ensure that all our gas struts are made to the highest levels of quality and will continue operating optimally levels, even in sandy, dusty or salty environments. Forget the days of corroding gas struts and sand and dust jamming.
Plus, our brass guided shafts and well-oiled seal ensure that the struts always glide smoothly. The additional backup seal is there to kick in if the primary seal fails. Combined with our dampener to ensure the struts don’t slam and cause significant injury and our ability to create custom sized gas struts with individualised weight capacities, there are plenty of reasons to choose Dunn & Watson for your gas struts.
