Here in the United States, a houses are broken into 4 times very minute. The garage is one of the most common points of entry for burglars who can enter your garage through the main garage door by using a coat hanger by hooking and pulling the red hanging quick release rope on the trolley rail.
This SecureShield device help to protect your family from
outside access to your garage via your garage door by covering the quick release rope but
still allowing you to pull the quick release rope in the case of an emergency to open your garage. It is
easy to install and works with most garage door openers. Features:
- Helps prevent garage door break-ins
- Easy to install in minutes (no special tools required)
- Works with most brands of overhead garage door openers (Note: (SecureShield is designed to work with most chain drive and
screw drive garage door openers. It will not work with belt drive garage
door openers and all models made by Linear.)
- Protects the quick release but still allows you to pull the emergency rope as normal
