4" PVC pipe saddle clamp

Saddle clamp for a 4" Sewer & Drain pipe commonly used in dust collection. Calling it 108mm as that's a close measurement in metric. I have 2 versions - a tight fit one and one that leaves a gap behind the pipe so there's additional room for fittings that bring the pipe off the wall a few fractions of an inch. If you use one please let me know how it went, I'm still fiddling with the sizes and would love your feedback.

UPDATE: I made a bunch of these to hold up 4" pipe for dust collection
