Telescopic gas spring 535 mm 20 kg – code: M3520536 – Trem

Trem 535 mm 20 kg telescopic gas spring – code M3520536

The telescopic gas spring Trem M3520536 is a hardware component designed to support the opening and holding in position of doors, hatches, and panels, in contexts where assisted and controlled movement is useful. This version is identified by a open length 535 mm and by a reaction 20 kg (F1), features that make it suitable for installations in technical environments, including maintenance and onboard outfitting.

The datasheet also includes the main dimensional measurements useful for checking clearances and replacements: body Ø 19 mm, stem Ø 8 mm and stroke 220 mm. For a correct choice it is always advisable to compare the measurements of the existing spring and the geometry of the mounting points of the application.

Main features and details

Product identification data

• Brand: Trem
• Product code (Supplier product code): M3520536
• SKU: TREM0000070
• Category: Hardware (Plumbing and Hardware)

Available dimensions and specifications

The following information is reported for the variant M3520536:

• Open: 535 mm
• Body: Ø 19 mm
• Stroke: 220 mm
• Rod: Ø 8 mm
• Reaction (F1): 20 kg

Note on variants

Within the same family there are different variants with different lengths, strokes, and reactions. This is useful when you need to:

• replace an existing gas spring maintaining equivalent clearances and performance;
• adapt the support according to the weight of the hatch/panel and the leverage generated by the mounting points;
• standardize multiple installations on a boat or on a system, choosing consistent codes for similar applications.

To avoid errors, it is important to select the correct code (in this case M3520536) and check the dimensions reported in the table.

Typical applications

A telescopic gas spring is commonly used as support for openings and closings where assisted action is desired. In nautical and plant engineering fields it can be used, for example, on:

• lockers and hatches inspection;
• doors of technical compartments and access panels;
• covers and hatches where it is useful to keep the position open during maintenance interventions;
• technical fittings and furnishings with flip-up opening (when the dimensions and reaction are compatible with the installation).

The choice of the spring depends not only on the nominal reaction but also on the mounting geometry: distance of the fixing points, opening angle, and available space. In case of replacement, direct comparison with the installed spring is often the fastest and most reliable method.

Operational advantages

If correctly sized and installed, a telescopic gas spring can offer practical benefits in daily use:

• Opening support of hatches and doors, reducing the manual effort required.
• Position retention during access to technical compartments or during inspection operations.
• Clean integration into hardware systems, thanks to a compact format and defined dimensions.
• Ease of replacement when you have the code and measurements (open, stroke, diameters), useful in scheduled maintenance or restoration.

This Trem variant M3520536 provides a clear set of dimensions (535 mm open, 220 mm stroke, 19 mm body diameter, 8 mm rod diameter) that facilitates the verification of dimensional compatibility with the existing application.

Usage and notes for selection

Recommended checks before purchase

For a correct selection (especially in replacement), it is recommended to check:

• code reported on the existing spring (if present) and comparison with M3520536;
• extended length and stroke (to avoid end-of-stroke or interference in closing/opening);
• body diameter and rod diameter for compatibility with brackets and available spaces;
• reaction (F1) in relation to the hatch/panel and the position of the fixing points.

Mounting instructions (generic)

Installation methods may vary depending on the type of hatch and the brackets used. In general:

• ensure that the fixing points are solid and suitable for the intended use;
• check that, with the hatch closed and open, the spring works without interference and without strain;
• in case of doubts about sizing, consider comparing with a variant of the same series with different dimensions or reaction.

Packaging

The product is indicated with packaging 1 / PCS. For installations requiring two springs (for example on wide hatches with two support points), consider purchasing the appropriate quantity based on the project.
