This unique system from Allproof utilises aspects from our two original designs, the cantilever bracket and threaded leg system.
We have learnt that a securely mounted frame greatly increases strength in areas of use, especially in high traffic areas, and the support legs provide reinforcement as the grates become wider.
The frame cleverly makes the adjustment required to take up the differing remaining space to the building with our in house fabrication.
When setting out for a concrete pour construction anchors will be fitted into the boxing and left protruding into the formed channel when boxing is removed.
This allows the “bolted bracket frame” to drop in onto and be fastened to the bolts at a later stage. This removes the requirement of the system to be on site until later in the construction schedule, removing pressure around time of pour.
This system has been designed for pedestrian foot traffic with a load class rating of A.
