Main Performance Features of the Coiler: 

The shell is made of cast aluminum and is cast using a single molding process, with a very high surface precision.
2. Equipped with an internal locking mechanism, it allows for stopping and starting at any position during the opening and closing of the roll film mechanism, without the need for any auxiliary devices.
3. Key components such as gears, gear shafts, and two-way self-locking devices are all precision-forged from 45# steel and heat-treated.
4. All surfaces are treated with an inner galvanized and outer powder-coated double rust protection, with standard parts made of stainless steel.
5. The handle features a hole at the 2/3 mark, where installation results in a reduced rotation radius, making it possible to fit in small spaces as well.
6. Reasonable speed ratio and torque make the operation more effortless and convenient.
