Scope and common interpretation errors
For everyday equipment covers and shaped accessories, without a universal draft or opening ratio.
Stretching over a step loads the opening locally. Sharp corners, cuts and sudden thickness changes can initiate tears; repeated removal differs from first installation.

Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Record real handling | Photograph grip points, steps crossed and tool contact. |
| 2 · Inspect weak regions | Check openings, hole edges and corners for notches and abrupt thickness changes. |
| 3 · Compare installation and removal | Use specified motions and observe first-use and repeated damage. Separate damaged test specimens. |
A comparison to avoid misinterpretation
Repeated cracks at the same user-gripped opening justify reviewing grip area or opening shape rather than only thickening the entire cover.

Frequently asked question
Does overall thickening solve every tear?
It may increase assembly force; validate local geometry.
