Installed in 30 seconds using the age-old housewife trick. Simply place the end cap in hot water (really hot 90) for 20 seconds, pour off the water, install the end cap - done.
30mm caps are delivered, which actually do not fit straight away. But with a little bit of expansion with the fingers, they fit quite well and are tight.
The ribs presented on the site are not the correct ones
I ordered 32mm end caps for a 32x4 batten; the tips received are 30x3, impossible to mount them on the slat!!! Unacceptable, moreover after research on the canvas, the 32mm slats are not standard and I can't find the appropriate end caps... Anger
