The cavity fixing for different board thicknesses and large
usage lengths
Cavity fixings
Spring toggle KD 3+4, KDH 3+4
BUILDING MATERIALS
▪ Gypsum plasterboard and gypsum
fibreboards
▪ Cavity floor slabs made from bricks
and concrete
▪ Chipboard
▪ Plywood
ADVANTAGES
APPLICATIONS
FUNCTIONING
▪ The long threaded rod of the toggle
fixings KD and KDH allows for use
with different board thicknesses and
thick attachments, and offers
maximum flexibility.
▪ An integrated tension spring causes
the catch elements of the spring
toggles KD 3+4 and KDH 3+4 to
open independently, thus allowing
for a simple installation.
▪ The wide transition beams ensure a
good load distribution. This achieves
a high load-bearing capacity.
▪ The nylon gravity toggle K54 allows
for the use of standard wood and
chipboard screws.

▪
▪ The gravity and spring toggle are
suitable for pre-positioned
installation.
▪ When placed in the drill hole, the
bearing elements of the gravity and
spring toggles independently swing
open behind the board.
▪ The KM 10 is specially suited to
fixing wash basins and urinals into
installation and cavity walls.
▪ No special installation tool required.
For a fast and convenient
installation.
