Balcony Attachment
The Balcony Attachment (code 37001, 1.6 kg, 320 mm long, 179 mm high) is a fixing device that secures Combisafe safety posts into cast-in channels or existing handrail fixings on balcony structures. The no-drill installation principle uses the permanent fixtures already built into the balcony slab rather than adding new anchors to the concrete, preserving the waterproofing and structural integrity of the balcony deck. This makes the Balcony Attachment suitable for both new-build construction phases and refurbishment projects on occupied or recently completed buildings.
Cast-in channels are commonly specified in balcony concrete to accept fixing brackets for permanent balustrade systems. During the construction phase, before the permanent balustrade is installed, these channels are available as fixing points for temporary edge protection. The Balcony Attachment uses these channels to provide EN 13374-compliant temporary edge protection without requiring any additional drilling, resin anchoring, or structural intervention. The installation is fully reversible, leaving the channels clear for the permanent balustrade installation that follows.
On balconies where the cast-in channel arrangement matches the spacing of the Combisafe Safety Posts, the Balcony Attachment allows a complete temporary edge protection line to be erected and struck quickly. This speed of installation reduces the time workers spend at the exposed balcony edge during erection and removal, directly supporting the Working at Height Regulations 2005 requirement to minimise edge exposure time. Altrad Generation supplies the Balcony Attachment throughout its UK and Ireland branch network.

Frequently asked questions
Q: How do you install edge protection on a balcony during construction?
A: The Balcony Attachment inserts into the cast-in channels or existing handrail fixings built into the balcony slab. The attachment is slid into the channel at the required post position and locked. A Combisafe Safety Post is then inserted into the Balcony Attachment, and Steel Mesh Barrier panels are fitted between the posts to form the edge protection line. The full installation process requires no drilling, no resin anchoring, and no modification to the balcony structure.
Q: Can you install edge protection without drilling into a balcony?
A: Where the balcony includes cast-in channels or existing handrail fixings, the Balcony Attachment provides a no-drill edge protection solution. The attachment uses the cast-in features already present in the concrete to achieve a secure, EN 13374-compliant post fixing without breaking the waterproofing layer or introducing new penetrations. The installation is reversible, so the balcony is returned to its original condition when the edge protection is removed.
Q: What is a cast-in channel fixing in construction?
A: A cast-in channel is a steel channel section embedded in a concrete element, typically a balcony slab, during the casting process. The channel runs along the concrete surface with a narrow slot open to the surface, into which special T-head bolts or fixing brackets are inserted after the concrete has cured. Cast-in channels are commonly used to attach permanent balustrades, façade brackets, and other components to concrete without drilling. The Balcony Attachment uses these channels to provide a fixing point for temporary edge protection during the construction phase, before the permanent balustrade is installed.
