This is a galvanized steel bracket. Here you mount the looprail on the 390 mm long vertical suspension brackets.

The 390 mm long Hörmann suspension brackets from Hörmann looprails for ProMatic, SupraMatic and EcoMatic garage door openers are attached to the floor. The lifting anchors were also treated as rail lifting anchors. To mount it, slide the base plate over the rail and screw it up following the hanging anchors. The screws must be present or can be ordered separately. The screw connection provides the base plate for securing the rail hanging.
