Air con pipe fixings/clamps?

[Fazerruss]

Morning all, just want to pick the brains of any HVAC engineers on here.
At the weekend I'm installing a twin split air system at the in-laws an I'm drawing a blank on what clamping solution is industry standard for this type of installation. The pipes will be in a zero traffic area and fixed to the wall. Although its on the back of the house I want something neat and tidy.
It's for 1/4 and 3/8 lagged copper pipe to attach to outside brickwork.
Cheers Russ

the pipe insulation is the issue so you will need stand off pipe clips

I don't think such clips exist for these sizes. I'll probably use some s/s strap band and fasten it to wall

3x2 plastic trunking? I think the insulation will degrade if it's not covered

That is the wrong lagging for that pipe used with refrigerant and outdoors

Normally use rubber lined clamps on refrigeration pipes.

What's the problem with it?
