A Cast-In Anchorage System increases site efficiency during the construction of a concrete building by removing the need to drill into the structure for Work Restraint or Fall Arrest anchors. Additionally an element of working at height to drill into ceilings and the risks associated with the use of hand-held power-tools are also greatly reduced or completely eliminated.

The design process starts when we prepare a horizontal lifeline layout that will provide running lines parallel to slab edges. We can estimate the number of cast-in parts from this information which if approved is re-presented in DWG format for setting-out on formwork decking.

We offer two cast-in systems:


Expendable plastic void formers are simply nailed or screwed onto formwork decking which form a tee shaped void in the concrete.

When the concrete has reached strength of 25kN/m3. The void is an accessible anchor point into which A Scissorsafe Anchorage Tool is inserted allowing connection for a personal safety system.

Scissorsafe Anchorage Points
are cast into the structure

Inexpensive Two Part Plastic Void Formers are nailed to the decking formwork from Scissorsafe designed setting-out plans, these ensure that drilled anchors will not be needed.

The Omega cast-in anchor system has been designed specifically to provide anchorage positions at floor level.

The anchor consists of a visible plastic protective housing containing a steel element that when embedded in concrete provides a connection point for a webbing sling, that in turn connects to a Temporary Lifeline, Lanyard or Work Positioner.

Cast-in anchorages offer the opportunity to plan safety anchor points early in the construction process meaning that concrete drilling and load testing is avoided.

Working in conjunction with us, we can provide advise for anchor point positions supported with setting-out plans in autocad format for site users.
