Bulldog GD20 Surface Mounted Garage Door Lock

Bulldog GD20 Surface Mounted Garage Door Lock

Q: What size bolts are needed. I bought m8 expansion bolts but they seem to be to big for the holes.

Hi, the GD20 Garage door lock should be used with M6 bolts. Thank you.

Q: Will it work with block paving

This will work on any solid ground, excellent and solid bit of security. I would line up the drill holes to avoid any grout lines and drill slowly to not crack the block paving.

Q: Why sell a product without selling the screws to use to fix it in position?

Because it’s up to you what fixings you use. Or fixing bolts

Q: How does it stick to the garage door?

This doesnt stick to the garage door it’s mounting plate is bolted to the garage floor. It stops the door moving forward/outward —- so is only good for garage doors that pull forward initially then up
