The PlexiDor springs have a long lifespan, but can break with years and usage. Luckily, it’s a cheap fix – you can see the kit with spare parts here – and they are easy to replace.
The spring kit comes with instructions. The replacement procedure varies slightly with door size, so you can also find the instructions for your door here:
- PlexiDor Small
- PlexiDor Medium
- PlexiDor Large
- PlexiDor Extra Large
- PlexiDor Extra Large manufactured before 2008
