Sliding glass doors have always relied on
wobbly pins, ugly bars or a variety of clever
but poorly-constructed gadgets for security.
While front doors were secured by strong, solid
steel deadbolts, sliders were left unsecured
despite the greater frequency of burglaries
through sliding glass doors than front doors.
Now, CAL America, Inc. is introducing a solid
steel double-deadbolt for sliders called the CAL
Lock.
