ABSTRACT:
A stop (1) for supporting a side of concrete form work (12) includes a deformable section (2) in the form of a collapsible sleeve (2) with an abutment (8). The sleeve is formed monolithically with the stop. A nail (13) with a head (13a) secures the stop (1) to a concrete structure or component (11) and when the nail (13) is driven its head (13a) runs up against the abutment (8). If energy in excess of the amount needed to drive the nail (13) in is present, the nail head (13a) striking the abutment (8) axially collapses the sleeve and damage to the stop (1) is avoided.
