Usage and installation notes

Checks before purchase

To correctly choose a telescopic gas spring, it is good practice to check:

• Length with spring open (here: 550 mm) and stroke (here: 229 mm), in relation to the available space and the desired opening angle.
• Diameters of body and rod (here: 19 mm and 8 mm) for compatibility with brackets or housings.
• Type of socket: this model shows eye hole 8 mm; check that pins and supports are consistent.
• Reaction (F1) (here: 12 kg) depending on the hatch and the fixing point.

General indications

• In case of replacement, always compare the data of the existing spring with those of the model M3512550.
• For outdoor or marine environment applications, keep parts clean and periodically check the condition of the attachments and fixing points.
• If the installation requires two springs, it is advisable to use identical models and mount them symmetrically, according to the hatch configuration.

For doubts about the choice (force/reaction or mounting geometry), it is advisable to provide the installation measurements and the code of the currently mounted spring, so as to identify the most correct alternative.
