2. Product Description
The K&F rotation clamp creates a robust and safe connection between the load adapter of a
suitable K&F flying frame and a standard truss or similar pipe system. It allows you to freely
rotate the suspended speakers and to lock them in the desired position using a clamping
lever.
Note that the half couplers of the K&F rotation clamp 450 are not interchangeable. Structures
made of trusses or pipes with a diameter of 48–51 or 60 mm, respectively, can be used.
In compliance with the German DGUV regulation 17 (BGV C1), the K&F rotation clamp is
capable of carrying a total load of 450 kg (speaker including flying frame and all further
loads such as cabling, load adapters, etc.).
The K&F rotation clamp can be used with the following products:

2.4 ID plates and safety labels
Tip
You can tell the 50-mm and 60-mm rotation-clamp types apart by their ID plates and the
mounted half couplers: The half-coupler of the 50-mm type is black while the one of the 60-
mm type is silver.
Before you start mounting a rotation clamp, always make sure you are about to use the
rotation-clamp type suitable for the application at hand (i.e. the pipe diameter).

3. Safety Instructions
Warning
Suspended loads pose a safety risk.
Only qualified technicians are permitted to perform the installation steps. Be sure to use
personal protective equipment at all times.
The technicians installing the speaker on site are responsible for and guarantee safe setup
and use.
Never use signal cables or power cords for suspending, aligning, or securing the systems.
Note that the suspension points (i.e. trusses or pipes) must comply with the DGUV regulation
17 (BGV C1) or similar locally applicable accident-control standards. The maximum load must
have been certified by an authorized expert.
Unless otherwise stated, use only KLING & FREITAG original parts for mounting the speakers.
Never use other parts (in particular, parts made by third parties not listed in this manual).
Be sure to always visually inspect all safety-related speaker and accessory components
before use. If there are signs of wear, cracks, or deformation, etc., replace the affected parts
immediately. Visual inspection also includes checking all screwed connections of supporting
components.
The information described here does not relieve the user of the duty to follow the given
safety requirements and legal regulations.
Never make any modifications to the K&F Drehklemme 450 or replace individual
components.
3.1 Maximum Load
Warning
Be sure to load the K&F rotation clamp 450 with the K&F SPECTRA 212 flybar, K&F VIDA L
flying frame, K&F SEQUENZA 5 flying frame or K&F SEQUENZA 10 flying frame!
The maximum load including the flying frame, all speakers, and all connecting cables must
never exceed 450 kg (as required by DGUV regulation 17 (BGV C1)).

4. Mounting and Use Instructions
Tip
With early SEQUENZA 5 load adapters, the load bolt may not smoothly slide into the load-
adapter hole. This is due to the load-adapter coating.
In this case, drive the load bolt carefully through the adapter by applying gentle blows to the
bolt using a plastic hammer.
Next, pull the two components apart again and attach the flying frame to the rotation clamp
as detailed below.
The following illustrations show an exemplary assembly of the K&F Rotation Clamp 450.
1) Insert the load adapter into the
identified flying-frame bores.
2) Fold back the linchpin and pull it
out of the load bolt.

3) Pull the load bolt out of the load
fork.
4) Place the rotation clamp with the
load fork onto the mounted load
adapter.
