Link: Zip Ties Violate Federal Regulations and UL 325 certification requirements.
Never use a zip tie to lock your garage door emergency rope mechanism. Using a Zip Tie prevents easy access to the life-saving operation intended by the emergency mechanism. There are false claims on the internet that the zip tie can be easily be broken by using two hands. This is simply not true especially if a vehicle is parked in the garage making the angle of access difficult, let alone when suffering from smoke inhalation! Ask any fire department staff and they staunchly warn you against using zip ties on your garage.
The Garage Shield allows for easy access to the emergency release rope, while still blocking intruders from reaching the rope from the outside. All this and installed in only 4-6 seconds ….and without TOOLS!
