## Questions & Answers

**Q: Is this OK to use on the outside of the garage, is it waterproof?**
A: Yes, it is designed to be used on the outside of the garage door. It is supplied with a plastic dust cap which will help prevent water getting into the lock.

**Q: Does this come with a cover to keep water out of lock?**
A: I bought mine about 5 years sgo, it did come with a cover over the bolt, but make it water tight around the bolt, as the water will fill up the hole you've drilled, & make the bolt rusty.

**Q: Is the key cylinder drill proof, and the cylinder pin hacksaw proof**
A: yes it is drill proof and hawsaw proof and i find it a excellent garage door lock                    bill

**Q: My garage has a 2cm high piece of rubber along the end of it (for reducing noise and water getting through I think); could I still fit this?**
A: Would think you would have to fit it over the rubber as it needs to be flush on the ground think the bolts are higher than 2cm it is a good product .
