The nailing aid for concrete construction products makes it easier to nail the cans. The 40 cm nailer nails the lid and cans to the formwork without injuring your fingers - even if the second reinforcement has already been installed. The distance between the receiving pins is 60 mm, so that any standard can lid can be picked up, positioned precisely and nailed down. The mounted magnet that picks up the nails can be reordered in the shop.
