Frequently Asked Questions
This notch is found on our steel or stainless steel covers without hinges. We produce our covers with very little tolerance and gap dimensions. The cover and frame are then (after galvanising or passivating) optimally realigned. The notch serves as a marker, so that this optimal fit is not later lost by placing the cover into the frame the wrong way. For an optimal fit, the notch in the cover should find the notch in the frame! The HAGO notch is seen today as a sign of quality.
