Brick description Good morning, Please can you describe the number of holes/vents in the center of this brick? ... I'm looking to understand if the product is the old version or new replacement version of this line. (Ie whether it has 5 or 10 holes). Many thanks for your help! Existing Answers We have a mix of old and new versions across the company, the most resent delivery was in our Chester branch so I would say that these would be the new configuration
