Metal access doors are available in four versions. Two of them - DM and DMN - are classic access doors with varying raw materials from which they were made (DM - door made of steel sheet, covered with epoxy coating in white or - for selected models - an antique colour; DMN - made of polished steel sheets in a chromonickel colour, giving them a noble look). All of them are equipped with elements facilitating installation and convenient for opening handles on door leafs.

Optionally, at the customer’s request, DM-series doors can be equipped with a Yale-type lock.

The remaining groups are inspection doors (DMW and DMNW series).
