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.

Socket Extension
APTUS supplies threaded studs in a variety of lengths to suit the slab or beam depth between the APTUS elements. Where the slab or beam depth is larger, socket extensions are used to extend the threaded stud to the required length.

Top and Bottom Shutters
APTUS supplies laser cut steel top and bottom shutters for precast elements to ensure the APTUS bars are cast into the element within the required tolerance. Bottom shutters are supplied to suit the required tappered base of APTUS elements. Shutters can be reused and the number shutters required for a job will be dependent on your production schedule.
