The Garage Protect provides home security with a "patented" design that outwits burglars. Many garage doors have a design flaw that allows for criminals to easily break in and access the garage without any damage or evidence of entry. It allows them to release the emergency release lever using a wire coat hanger in about 6 seconds. Garage Protect has a patented design that blocks access to the release mechanism. The Garage Protect garage door security system attaches in less than 5 minutes and can be installed by anyone. Once installed, garage protect requires no effort to maintain. Eliminate the 6 second break in with the Patented Garage Protect. Please note: Is not compatible with some Genie 1000 release mechanisms. When in doubt please contact us so we can confirm compatibility. Works on most garage door release mechanisms. DO NOT ATTEMPT TO MODIFY THE GARAGE PROTECT. If it does not easily attach to your garage door opener arm, and easily clear the garage door rail, and easily install in less than 5 minutes. STOP and call us. You are doing something incorrectly.
