For many years now the TOPP ACK 42 has been the motor of choice for the window and conservatory industry.
Shown here with a pair of TOPP universal brackets but when they are fitted to our roof vents we use our own purpose made one piece aluminium bracket.
If your vents are a special colour and you need the motors to match then the TOPP ACK motor is perfect as we can colour code it to match your vents.
With its cast aluminium body and variable chain extension up to 400mm it has long been an industry favourite.
There is an on site chain adjustment by means of a threaded stud which must be locked into position after the correct settings have been made.
