Aluminum enclosure for PSU - how to connect PE?

I'm looking at this Hammond enclosure for PSU:
https://www2.mouser.com/ProductDetail/546-1455N1601

I know that per safety regulations the metal enclosure should be bonded to PE. This particular enclosure consists of 4 anodised aluminum pieces: 2 side covers, U-shaped channel and a lid.
My main question is how do I reliably bond all these pieces to PE? Side covers will have some cut-outs, so I can attach bonding wires to one of the screws - this is an easy part.
However, I don't think that I can rely on the connection between side lids and an U-channel. And top cover doesn't have any screws at all.

So how would you go about this? Are there any ways to bond this type of chassis to PE properly?

They have electric continuity between all faces.
