Guardian Lock Upgrade For Sliding Patio Doors
Shipping calculated at checkout.
Increase the security of your sliding patio door with this interior top-bolt lock accessory.
Although all of our patio door locks are highly secure twin-point types, this top-bolt lock gives an extra layer of security when the door is fully closed.
These are available as an upgrade only, and must be ordered at the same time as your patio door.
Please order quantity of two when used with 4-panel patio door systems
