Bricklaying Brickie Profiles X4, 40x40x2.5 mild steel box section approx 1875mm long each with deep 1mm grooves for string line up the full length at 75mm increments. Box section will be open at each end. Iv put tiny notches to identify the top as lengths can be shorter but the 75mm marks are all from the bottom end. Any modifications can be done just ask. These are made to order. Thanks. Nick.
