Movement in new Electric Roller Door - What's Normal?

[bobbyrobby25]

Hi Everyone.

A few weeks ago we had a new garage door installed. It's an insulated roller door with 77mm slats.

My question - I noticed some play with the door. I can lift it perhaps 1-2cm when its in the down/locked position. I'm not forcing it, it's just the weight of the door. It feels firmly locked when it reaches that height, but I want to understand if this is normal. I've never attempted to lift such a door, and have never had such a door...but I was rather expecting that part of the security here is that it pushes/compresses firmly to the ground. Otherwise getting leverage seems rather trivial.

I get it is a garage door, and not a bank vault door - but I want to feel comfortable with the installation. I do understand that anyone determined enough can break in.

I did query it with the installer, including my question about leverage - they said this was normal and does not affect security, and stated they've never known such a problem to result in a breakin. They came recommended, are well established and reputable, but I still would like to understand others experience here.

Thanks!

I wouldn't worry you don't want the door forced against the ground, a metal door will expand in the sun, you don't want it distorting.

As long as the bottom seal rests against the floor once you release it then shouldn't be a problem. It should compress slightly in the closed position.
