FAQ: Which Gas Strut Do I Need?

How do I know what size gas struts I need?

In general the length to choose for gas struts is about 55% of the height of the door you are trying to keep open. So if you have a door that is 1000mm in height a 550mm long gas strut would be about right. In simple terms we are talking half the door height plus a bit when determining optimal gas strut length.

What gas struts do I need?

To calculate the size and the force of the Gas Strut you require for your application use the following guidelines. The extended length of the Gas Strut should be approximately 60% of the door or hatch length – e.g. a 1000mm high door should have a Gas Strut length of approximately 600mm.

How do you measure gas struts to replace?

How to Measure Step 1 – Extended Length. Measure the gas strut from middle of end fitting to the middle of the end fitting when gas strut is fully extended. Step 2 – Diameter. Measure across the Rod/Shaft. Step 3 – Newton Meters or Force. Step 4 – End Fittings. Step 5 – Order your Gas Strut.

Do gas struts work both ways?

With a couple of gas springs on either side of the lid, it works a different way. Now, when you gently lower the lid, the weight of the metal and glass forces the pistons into the gas springs, compressing the nitrogen gas inside.

How long do gas struts last?

In normal use they are very durable however they do have a life span. Loss of efficiency can typically start to occur after about five years of use, though some last considerably longer. Most failures relate to gradual loss of gas pressure which prevents them supporting their design load.

How do you release gas struts?

Using the Allen key provided undo the grub screw until gas can be heard escaping. Then re-tighten the grub screw. Only release the gas in one second bursts to avoid releasing too much gas. Repeat the process until the gas strut is behaving as desired.

Are gas struts constant force?

A Camloc gas strut is a sealed energy source containing pressurised inert gas and a small amount of oil. At the end of the extension stroke, oil damping occurs due to a hydraulically‐cushioned zone. These features help protect hinges and mounts by applying constant force with a damped end of travel.

Where should gas struts be placed?

It can also be identified by the moving mounting point being located closer to the hinge than the fixed mounting point. Unless a means is utilised to lubricate the rod, then the strut should always be mounted rod down to ensure proper lubrication of the main seal.

How do I choose a gas spring?

choose the type of gas spring re- quired, clarify the function of the gas spring – to keep open, keep closed, or automatically open, find the optimum fixing points and the stroke, calculate the required spring force, • determine the technical qualities.

Are all gas struts adjustable?

Yes, all our gas struts are adjustable gas struts. If you push the valve, the gas is vented out and the force is lower.
