FAQs
1. What are the most secure ground door lock types?
Floor Barricades: Heavy-duty plates anchored into the floor with a removable metal stop. Highest resistance to kick-ins. Vertical Deadbolts (Cremone Bolts): Rods that lock into both the top frame and the floor simultaneously. Heavy-Duty Foot Bolts: Spring-loaded or manual bolts that pin the bottom of the door directly into a recessed floor strike.
2.How does a ground door lock mechanism work?
Force Transfer: Instead of relying on the door frame (which can split), these locks transfer the force of an attempted entry directly into the building's foundation (concrete slab or floor joists). Physical Obstruction: They create a "dead stop" at the base of the door, preventing the door from swinging or being pried upward.
3.How to install a floor bolt for a double door?
Alignment: Close the doors and mark the center point where the bolt meets the floor on the "inactive" leaf. Drilling: Use a masonry bit (for concrete/tile) or wood bit to drill a hole slightly deeper than the bolt’s throw. Strike Plate: Clear debris and insert the floor strike/dust proof socket. Use adhesive or anchors if needed. Mounting: Screw the bolt housing onto the interior face of the door, ensuring the rod aligns perfectly with the floor hole.
4.My ground door lock is stuck and won't open – how do I fix it?
Spray penetrating oil like WD-40 into the keyhole and moving parts, wait 5-10 minutes, then try again. If debris is blocking it, clear it out first. For a broken key stuck inside, use needle-nose pliers to remove it. To prevent future jams, lubricate your ground lock every 3-6 months with silicone spray.
5.What is the best heavy-duty ground door lock for parking spaces?
Look for thick steel construction (3mm or above), hot-dip galvanized anti-rust coating, anti-pry design, and a smooth lifting mechanism. For most homeowners, a manual heavy-duty ground lock offers the best balance of security, durability, and value. Remote control or solar-powered models are ideal for commercial parking lots.
