The ring transport anchors are made of special high-grade steel and are supplied in different weight categories. The anchors and their grooves are secured to the casing with a mounting plate or a screw. The ring clutch is inserted into the recess of the cast-in anchor and the locking bracket is closed by hand. The ring clutch is thus secured to the anchor in a matter of seconds. To disengage, the bracket is opened with the hand and the ring clutch can be removed.
