ABSTRACT:
The invention relates to a device10for stabilising ladders60that bridge a floor70and an elevated structure, such as an elevated floor70in a multi-storey construction. The device70includes a body that is fixable to the elevated structure and an arm50extending from the body. The arm50has a tab52which engages a beam64of the ladder60when the ladder60is abutting an edge40of the body. In this arrangement, outward sliding movement of a heel of the ladder is prevented and thus the ladder60is stabilised.
