“Marsilii” is the Marsilii coplanar door with automatic locking system and concealed hinges.

It is a project that successfully integrates doors and walls, an increasingly exclusive synthesis between furnishing elements and interior design. Perfectly coplanar to the wall, this door offers the possibility of having coplanar handles as well. It is the result of all the highest features of Marsilii’s products put together.

Concealed hinges on the inner side of the door; Door frame finished off with the door casing coplanar to the panel; Special armouring made of four steel sheets, which are 65/10 thick on the entire door’s surface and 105/10 thick on the lock’s area, where there are also three “top, center, low” reinforcements of 30/10 thickness.
The aesthetic innovations are the ROTARY and SLIDING handles, which allows the Marsilii door to have no protrusions and gives it an appearance of total coplanarity. Besides that, thanks to the boiserie (wood panelling technique) the door is insurmountably elegant.


The Marsilii security door features a superb mechanical invention, which allows the bolts to fit into their seats by simply placing the door closer to the wing.
The locking operation, so far carried out by the user with a key, is automatically performed by the “Custos P 12 laser” lock itself.
The door is constantly reinforced by six independent and burglar-proof pins, which are longer than 10 cm and come 3 cm out from the door leaf. The key is only needed to open the door from the outside; From the inside the Marsilii door is opened by simply turning the doorknob or the rotary (or sliding) handle.


Security doors requiring electrical controls are equipped with the “Custos P 12 Laser E” lock.
The door is closed mechanically without the aid of electrical devices, but it can be opened both mechanically and electrically


Counter frame

It is realized in 25/10 galvanized sheet, properly shaped to contain the frame, making it unassailable to levers such as crowbars and screwdrivers.
This system also allows to have major endurance during the assembly, in case the threshold is stalled higher or lower than it should be (about 2cm).



It is realized in double 20/10 galvanized sheet, properly shaped to fit into the counter frame and stove enamelled. It also has latch recorder, concealed hinges with self-lubricating bushes, adjustable to up/down or left/right. The EPDM gasket is embedded in between the frame and the counter frame, isolating the inside from the outside both thermally and acoustically.


Door leaf

It is made of four sheet metal panels 65/10 thick on the entire surface, 40/10 of which are made of Manganese steel. In the hollow space there are three omega reinforcements made of 30/10 sheet. The door is insulated with three different materials: thermal, acoustic and thermal-acoustic insulations, which cover the entire door’s surface, lock’s area included. The door leaf is also equipped with a highly reliable clamping unit: the “Custos P 12 Laser” with automatic locking system moves six pivots 10cm long and is provided with the European profile cylinder, protected by a coplanar defender. The patented draught excluder functions as a seal both on the floor and on the frame’s gaskets, obtaining a result comparable to the fixed threshold system without the risk of having obstacles in the passage area.



It extends over the top of the door without any structural variation. It can be made of vandal resistant laminated glass of 18/19 thickness or anticrime glass of 19/21 thickness (under request also 26/27 or 39/41).


Exclusive features of the door

Constant guarantee of security, no longer tied to the use of keys; Practical opening from the inside with effective anti-panic function; Anti-jamming device: the key is always recast with the position of the pins.
