Adjustable Gas Struts
Metrol Are Pleased to Offer a Wide Range of Adjustable Struts
We stock struts with heat-treated (QCQ) rods with diameters from 6mm up to and including 20mm. Within these different diameter ranges, we offer struts of varying lengths, and each gas strut can vary in force from 30-400N depending on how they are adjusted. When browsing our extensive range, look out for the NS-V code, which denotes adjustable struts made from steel where the strut body is powder-coated. The NS-SS-V code indicates stainless steel adjustable struts with a chrome-plated rod and stainless steel body, which is a more corrosion-resistant option, particularly suited to marine and coastal environments. Please remember to add 5mm to the body length for each of our stainless-steel adjustable gas struts.
Suitable for a Wide Range of Applications
Adjustable gas struts are ideal for use in several different settings, from light duty to heavy duty use. All our variable force struts have long-lasting gland seals for heavy duty applications. Common uses are listed below:
- Machine guards
- Electrical control cabinets
- Car bonnets
- Car boots (tailgates)
- Access hatches and doors
When using struts for the above applications and others, we would always recommend the use of ball joints to avoid side loading and uneven wear of the piston rod and seals. For our adjustable gas strut range, we provide detailed installation instructions, including the use of gas strut brackets and end-fittings. Please also note that when choosing your desired variable force gas struts on our individual product pages, the extended length will increase when adding end fittings.
Varying the Force of Your Adjustable Gas Struts
Our variable force gas struts contain a pressure release valve. This is what makes them adjustable. All our struts start with a force that is at the top of the force range (400N). When adjusting using the Allen key provided, the pressure in the cylinder will drop, lowering the force. To reduce the force, use an anti-clockwise turning motion with the Allen key for a quarter turn. Venting the gas for one second will reduce force by approximately 20-50N, depending on the range. We recommend testing the struts in their desired application after each vent to check they are at the correct force. Based on the positioning of the release valve, you will be relieved to learn that you do not have to remove the unloaded strut from its application when venting unless not doing so creates additional hazards. Repeat this process until you are happy with the resistance and support provided by the variable force struts. Make sure to repeat the process by an equal amount on the other strut. Full adjusting instructions can be read here.
Need Something More Specific?
We can also create custom gas struts. Simply let us know your required specifications, including diameter, stroke, extended length, force and the fittings you need, and one of our friendly team will be in touch to discuss.

Adjustable gas struts can be hazardous as they are filled with compressed nitrogen. Whilst our range includes struts that can operate from -30C to +80C, they should be protected from damage and never opened, modified, drilled, welded or subjected to excessive heat. We also sell gas strut protection tubes which may be required depending on the application.
