Clamp-on Ladder Level

I designed this for my voluntary fire department as a relief in finding the correct angle of the ladder you are trying to errect. Simply clamp this handy device on one of your first beames and it will show you the best angle in which the ladder hast to be (~65 degrees). It is designed to fit the standard EU ladder beams (30mm x 30mm)To build this you need:-2x M4x15 Allen Screw-2x M8x10 Allen Screw-2x Leveling DeviceYou can find a Leveling device in you local hardware store or under this link: https://www.amazon.de/gp/product/B000297U2U/ref=ppx\_yo\_dt\_b\_asin\_title\_o02\_s00?ie=UTF8&psc=1In some cases the Device ist a bit loose.
