About Our Manually Operated Roller Shutters Products & Services
The most popular and cost-effective among all kinds of roller shutters is the manually operated roller shutter. It is completely environment friendly without the need for electricity and has low maintenance costs that can offer you with good basic shutter convenience.
Generally, this kind of shutter is operated with the use of crank and winder. For our commercial manual roller shutters, they are usually installed in arcade stalls and shops with open fronts. This way it will be easy for you to operate by just simply pushing it up or pulling it down and can be locked by bullet locks or chain keeps.
Spring Assist with Bottom Bar Key Lock
Ozroll’s spring operated roller shutters offer a practical solution to commercial applications such as shop fronts, bars and canteens where added security is required. Assembled orders are supplied with a spring inside the axle which is specifically tensioned to the weight of the shutter, allowing simple and easy installation and operation.
This design provides a smooth, effortless motion in opening and to close it is as simple as pulling the curtain down using the handles provided, then locking it in place with Ozroll’s Bottom Bar Key Lock. The key lock can be custom ordered to face outside the shutter towards the head box (standard) or inside the shutter (reverse).
We are also able to supply an Intermittent Flat Locking Slat for applications where it is necessary for the lock to be accessible at a point in the curtain which is above the Bottom Bar.
Tensioning Assist Springs
The U shape tool provided in the kit box is used for stabilizing the axle and assist spring when the amount of turns on the spring must be adjusted. Re-tensioning the springs to the correct amount of turns is simple:
- Disconnect the spring fasteners from the Octagonal steel axle (Ensure the U shape tool provided is placed into the crown position of the assist spring when doing so) This will allow no movement. The curtain can be left sitting in the window and guides; there is no need to remove the curtain.
- Depending on the tension required remove the U shape tool and hold onto the Octagonal axle when performing this.
- Proceed to turn the axle either forward or backwards one or however many required complete rotations depending on whether more or less turns are required.
- Once the assist spring is tensioned correctly place the U shape tool into the crown position of the assist spring to ensure no movement when connecting the spring fasteners.
- Proceed to connect the spring fasteners to the octagonal axle
- Once connected remove the U shape tool whilst holding the octagonal axle and slowly release the axle and allow the curtain to roll up to the top position of the guides (where the V stoppers hit the box end inserts). The assist spring should now have the correct amount of tension/turns required.
- If the curtain is still not tensioned correctly repeat the instructions accordingly until the desired tension is found.
