The rollfomer is similar to a cable reel in that it provides power or external contact points for the air duct on the one hand, and also has a power plug to connect to the power supply on the other hand. Act as a mediating connection. The difference is that the rollfomer is often directly connected to work lights and can be used without external light tubes.
When in use, pull the cable connected to the work light down to a suitable distance and stop it. The locking device inside the rollfomer will automatically start, and the cable will not lock. After use, you can gently pull the cable, and the cable will automatically cross the self-locking device and retract.
