## Questions & Answers

**Q: How can I ensure that the DoorJammer DJ3 will fit my door?**
A: To ensure a proper fit, measure the gap between the bottom of your door and the floor. The clearance must be at least 0.25 inches (1/4”) and no more than 1.5 inches. The DoorJammer DJ3 is designed for inswing doors with a minimum of 3mm clearance.

**Q: Can DoorJammer DJ3 secure all door types?**
A: The DoorJammer DJ3 secures inswing doors up to 100lbs, perfect for interior, travel, and hotel doors. It’s NOT compatible with outward-opening doors. For doors over 100lbs, consider the DoorJammer DJ4 Lockdown for enhanced security.

**Q: Can I use DoorJammer DJ3 on all floor types?**
A: Yes! The DoorJammer DJ3 works on most flat surfaces, including tile, laminate, wood, and carpet. For thicker carpets, it includes a neoprene extension foot for extra grip and stability.

A: Absolutely! No tools are required. Simply position it under the door, twist the screw to secure it, and pull upwards to release. Its quick-install and emergency-release design makes it user-friendly and reliable.

**Q: Can DoorJammer DJ3 be used on doors with weather strips or protective seals?**
A: No, DoorJammer DJ3 is NOT compatible with doors that have weather strips or protective seals. These can interfere with the device’s stability and effectiveness, so it’s best used on doors with flat, unobstructed surfaces.
