Hooks G and H can be fitted to all our profiles except those with rope-operated wings.

The height of the profile is irrelevant, as they are fixed across the width of the profile. Mainly on the top of the upper section, which has no wheels. As Spacer I is fitted to 30 x 30 rungs spaced at 250 or 280 mm intervals, there is no maximum section size to be observed. The K anti-theft support can be used on upright sections with a maximum diameter of 100 mm. Please note that the ladder can be positioned vertically or horizontally on the wall.
