Drilling Deceuninck door for roller blind brackets

[Careful_Bodger]

I am after advice if I can drill or not into the locations shown in the pics for mounting roller blind brackets on the back of a Deceuninck door.
Will I hit anything critical, and is there likely to be metal reinforcement? Screws are about 1" long. Comments welcome

I would ask the manufacturer/supplier/fitter, but you know that run-around feeling you get sometimes..........

Yes they should be metal reinforcing there

Thanks! There was indeed 'something there' for each of the lower fixings that needed a clearance hole drilling out. A 2mm pilot did the trick. The upper fixing (there are two screws per bracket) was just into plastic as far as I could make out.

Anyway, all sorted now
