This reference includes 40 kits composed by
1 x BT metal piece M4, 36x11x7 mm
2 x Leg BT 4,5,6 yellow
1 x Cap BT 4,5
The cavity plug universal BT plus M4 guarantees highest loads in plasterboards and simple and quick handling. At the same time the BT is universally useable for board thicknesses from 10 to 70 mm. No additional setting tool needed. Make sure that the gap behind the board is at least 51 mm and push the BT plus through the drill hole (Ø 13 mm). The stable metal part toggles in the free space behind the board. With pulling back the BT and simultaneously sliding the plastic washer into the drill hole the plug is installed. Break off the remaining plastic legs as shown in the instruction. Now you can fix your application with a metric screw M4 into the internal thread of the metal part behind the board.
