• for common varieties - 204 x 82.6 cm;
• for reinforced metal products - 205 x 85 cm or 205 x 95 cm;
• in double doors - 205 x 160 cm.

However, modern builders rarely adhere to these standards. Therefore sometimes the sizes of entrance doors with a box in shop happen not all are presented. You have to order the product with the required parameters in the production.

But their dimensions are calculated in each specific case according to the individual design plan.

In nine-storey houses, the size of the entrance doors with a box is 128 x 255 cm.
