The smartphone must be equipped with a suitable COMPIT COVER for secure attachment to the COMPIT or +COM/UNIT mount. A smartphone cover with a special fastening mechanism allows the phone to be fixed to the holder by pushing and turning in the wide bayonet lock. The covers are made of shock-absorbing material, cover the outer edges of the smartphone and protect it in case of drop or impact. Thanks to the use of high-quality, wear-resistant plastic, the cover is extremely strong in the areas of greatest stress. The dual-fold cover, which is pleasant to the touch, makes it easy to insert and remove the phone.
