A custom gas spring may be needed when an existing specification does not match a product's installation space, movement or load requirements. Equipment covers, cabinet doors, storage beds and vehicle access panels can require different lengths, strokes, forces and end fittings, even when the gas springs look similar.
Start with the application and the result you need. Describe what moves, how it is mounted and whether you need lifting assistance or position holding. This helps establish whether a standard option can meet the requirement or whether a custom specification needs further review.
What to Include in a Custom Gas Spring Inquiry
Application: the product, moving part and intended operation.
Dimensions: extended length, compressed length and stroke, with measurement points clearly marked.
Force: the required value or the marking on an existing unit, if known.
Installation: mounting points, end-fitting details, available space and opening angle.
Operating conditions: temperature, moisture exposure and any material or finish requirements.
Purchasing details: sample quantity, expected production quantity and delivery destination.
References: a drawing, dimensioned photos or existing sample information.
For the connection details, review our end fittings and brackets. Confirm dimensions and compatibility for the selected product; a similar-looking fitting does not establish that it will fit the installation.
Confirm the Specification Before Ordering
Agree the proposed dimensions, fittings, force requirements and any remaining checks before an order proceeds. Where a sample is required, define the application test and acceptance requirements for the intended installation. Report changes to the load, mounting arrangement or environment before reordering the same specification.
Buyer Questions
Can I request a review without a complete drawing?
Yes. Send clear photos, available measurements and a description of the operation. Identify any unknown details so the next information needed can be discussed before a specification is proposed.
Can the force be selected from panel weight alone?
No. Include the panel's dimensions, hinge location, mounting points, opening angle and planned number of gas springs. These details help assess the requirement in the actual installation.
