All the things you’d expect plus attention to quality details. No edges to smooth or surfaces to flatten after fab welding.
The main point is the value. Paid $19 for the smallest single penetration. Using these for the prior pass through would have saved me a couple hundred bucks, easily.
Bonus. While the smallest was sized for control cable pass throughs, a light chase with an adjustable reamer and a BNC will pass through. Thought I’d have to cut and re-terminate. Products are well worth a consideration.
