An anchorage for anchoring an article to a bilateral flange which can have a width in a wide range of widths. First and second hooks are hooked over opposite flanges and securely retained thereon by a webbing strap of adjustable length extending between the two hooks. The webbing strap is permanently secured at one end to one of the hooks, and extends through a clamp on the other hook. The length of the webbing strap between the two hooks is fully adjustable in a wide range to accommodate the varying flange widths. As an alternative to a webbing strap and clamp, the hooks can be adjustably linked by an interpenetrating tongue and slot or buckle, mutually latched at a selected hook separation by a detent having projections urged into notches on the tongue. The anchorage is particularly suitable for securing a safety net to the lower flange of an I-beam in a steel-framed building under construction, since the anchorage is quick and easy both to install and to dismount while easily accommodating a wide range of beam sizes, and always leaves the top edges of beams free to allow them to support flooring without dismounting the anchorage.
