Our vinyl patio doors come featured with fully-welded construction, aluminum reinforcement, and superior wedging interlocks. Security is always at the top priority of our priorities with keyed, dual-point grappling hook locks. The patio door handles can also easily be upgraded to include a keyed, multi point lock with four locking points.
