The easily installed Big Jammer
Door Brace provides protection at your home,
business or hotel room. The Big Jammer is made from
strong 20-gauge steel and installs quickly under
doorknob and providing you with added security. Easily
adjusts with the push of a button to fit most hinged
doors. Rubber end caps prevent the Big Jammer door brace
from slipping even on fixed carpeting, but are removable
for use on sliding glass doors as well.
You don’t have to cut a broom handle down to size to
block the glide path of the sliding patio door.
End caps can be removed to allow for use on sliding
glass doors as well.
