I do not have a better drawing to provide. The photo in the attached is just showing smiliarity for pre-cast concrete, doesn't have to look exactly like what is shown (I hope that makes sense). There is no specific measurement for rebarb protrusion; as long as it does not create a safety hazard and can be delivered with no damage to equipment or handlers.

Hello, I do not. The drawing is there as an idea of what we are looking for, I hope that makes sense. It does not have to be attached, just individual slabs. Please do ensure slabs are fabricated in way for safe delivery. You will be going through a security gate, the only requirement is having proper identification and product paperwork.
