ipow Pack of 6 Flexible Roller Shutter Fasteners in Steel and Nylon, 155mm Universal Suspension Spring for Securing Electric/Manual/Solar Roller Shutter Slats, Apron Clip Compatible with Somfy

UNIVERSAL FLEXIBLE CLIP-ON FASTENER FOR REPAIRING A LOOSE ROLLER SHUTTER: The ipow safety spring is perfect for replacing broken plastic fasteners or old strap-type fasteners with screws; it is suitable for 8mm thick PVC and aluminum slats and various types of axles (steel, aluminum, wood) for manual or motorized roller shutters.
CLIP OR SCREW-ON FIXING TO THE ROLLER TUBE: Simply pinch the end and insert the fastener into a slot in the tube, ensuring that once inserted, it pops open again. Some roller tubes don't have slots but a groove or small holes; it's possible to attach a metal strap fastener by screwing it directly onto the tube. Don't hesitate to use as much support as possible on the roller tube axle; this will reduce stress on the fasteners. ERGONOMIC: The claw for the fastener on the ZF/DEPRAT/OCTO axle is split in two, making it easier to engage in the slot on the axle without twisting or weakening the roller shutter fasteners. HIGH QUALITY: The roller shutter adapters are made of nylon parts and a thin steel blade, which is durable, rust- and corrosion-resistant, and has a long lifespan. The nylon edges can slightly reduce noise. NOTES: Gloves are mandatory for installation because the blades are very sharp. Take photos before disassembly and after reassembly to avoid mistakes in the direction of travel.
