In itself, makes this fuse holder a good and high-quality impression. But when assembling I like some other reviewers, the problem that the distance between the two holders was too large for the backup and you are not completely stuck in two holders. But if, as is presumably intended, put the two rubber seals on the small red plastic sleeves the holders are pushed far enough along. So make the seals with regard to water tightness more sense than to mount them so you can see on the picture. A small leaflet with a simple drawing would certainly be helpful.
Not so much has given me that assurance only relatively loose and wobbly stuck in one of the two sleeves. For currents up to 60A, a good contact is very important. This can be resolved the inserted into the holder spring steel nachzubiegen something something should but I do not be necessary.
