An edge restraint apparatus for restraining a hard structure, including a substantially upright section (10) having a height; and a base section (12) extending from a lower end of the upright section (10) on at least one lateral side thereof. The base section (12) is essentially perpendicular to the upright section (10) and has a width. At least one of the height of the upright section (10) and the width of the base section (12) is variable. The upright section (10) and/or the base section (12) may be provided with longitudinal weakened portions such as indentations (16A- 16D), score lines (14A, 14B), or different material properties, in order to allow an unwanted portion of the section to be severed and removed. Extension sections (31, 41, 51, 61) may be provided which are engageable with the upright section and/or the base section. |
