Ancon Surface Fixed Channels
Surface Fixed Channels
Plain-backed channels can be surface-fixed to steel, concrete and in some instances, masonry.
The Ancon channels suitable for surface fixing are 36/8, 25/14, 28/15, 40/25, 49/30 and 54/33.




25/14 Restraint System
The Ancon 25/14 restraint system is designed to tie masonry to steel or concrete frames through a layer of insulation.
25/14 Channel is supplied in lengths of 2700 and 3000mm, and features pre-punched holes at close centres to ensure a fixing position is always located near the end even when it is cut on site.
Once the channel is installed, stainless steel SD25 or basalt fibre Teplo-BF-CT 25 wall ties can be positioned at any point along its length and are built into the bed joints of the outer leaf of brickwork.
See technical literature for product references and fixing centres for both ties and screws. Contact us for information when fixing to timber.
Fixing to Concrete
Leviat offer a choice of two concrete screws; the new, exclusive Ancon CFS+ and the original Ancon CFS.
The Ancon CFS+ can be used with all insulation types and accommodates an insulation thickness of 50 to 270mm. The CFS+ is a fully stainless steel fixing assembly which provides quicker, simplified installation and does not require a compression sleeve. The concrete screw end carries an ETA is capable of fixing into particularly strong concrete.
The Ancon CFS can be used with all insulation types up to 270mm thick. A pilot hole and an Ancon Stainless Steel Compression sleeve, the same depth as the insulation, are required.
More information, including wall tie and screw centres, is available in the Ancon 25/14 Restraint System technical literature.
