These are normally used for building cupboards and have a hole at each end and one at right angles in the middle. Size about 30mm long and 8 mm wide. I have also used these for many years, usualy singularly but sometimes in series for very high voltages (> 10Kv). The are quite good and less affected by the weather and uv than plastic pipe but I still prefer the old porcelain eggs! 73, Roger, G2AJV.
