Components

The design of the APTUS couplers allows them to be used in a wide range of installation scenarios including square & rectangular columns, blade columns, round columns, walls, façade walls, raking columns and all the possible transitions between. The APTUS couplers are designed to allow for +/- 15mm of vertical tolerance and +/- 3mm of lateral tolerance.
