Wallbarn Slope Corrector
Wallbarn slope correctors are circular wedge shaped discs which are designed to clip under the baseplates of adjustable support pads to arrest the fall in the roof deck. They are lightweight and easy to apply as they are secured to the baseplate by two clips at the side which hook, over the edge of the baseplate to hold them both secure.
Wallbarn slope correctors adjust the fall under the base, meaning that the support pad is always completely straight and the force down is always completely vertical. The weight of the slab is always going directly downwards and is far more secure.
