COMPLETE TRESTLE WITH 2 FIXING CLAMPS
The trestle is used to support the ladder or the knee joint when it cannot rest directly on the roof or a
window sill.
The trestle is attached to the underside of the ladder structure or knee joint by means of the 2 fixing clamps
provided.
The adjustable legs allow the trestle to be extended from 0.21 to 0.35m.
Installation of the trestle:
- Place the trestle under the ladder frame so that the trestle crossmember is centred and supported
under the ladder profile (1).
- Secure the trestle to the ladder structure with two fixing clamps (2).
Supporting the trestle:
- Unlock the telescopic legs by removing the locking pins (1)
- Extend the telescopic legs until they fit (2)
- Lock the telescopic legs by replacing the locking pins in the most appropriate hole.
- If necessary, insert a board between the legs of the trestle and the building structure.
