In an example, when the stability anchor (106) is coupled to the mounting mechanism (104) then the clamp is moved from non-clamping position to clamping position in the undercut section (112). Further, the lever (104c) of the present invention is accessible from the outside of the box (100) to enable installing and un-installing of the box (100) without opening the structure of the box. Moreover, one end of an actuating member (104e), such as bolt, is fixed on the mounting frame (110) and another end of the actuating member (104e) is fixed on the lever (104c) to allow varying the distance between the mounting frame (110) and the lever (104c). This accessibility allowing the shifting of the lever (104c) between the non-clamping position and the clamping position. Also, the stability anchor (106) is rigidly coupled to the outer wall (100a) of the box (100), preferably the roller shutter box, and is configured to engage with a base (104a) of the mounting mechanism (104). The foot portion or bottom portion (106a1) of the stability anchor (106) is configured to engage with the at least one slot (104a1) in the base (104a) of the mounting mechanism (104). Moreover, the outer wall (100a) and the mounting frame (110) comprises snap fits, allowing positioning and fitting the box (100) on the architectural opening (200) in the building in a suitable position wherein the clamp (104f) can engage with the undercut section (112). The outer wall (100a) of the box (100) further comprises opening (100d), preferably a longitudinal slit (100d) to face outward of the building. The box further comprises an insulation member (not shown) extending parallel to the longitudinal slit (100d) and positioned at the outer wall (100a) of the box configured to face a window or wall part of the building. The insulation member (not shown) defines a boundary between a cold zone of the box (100), facing the outside of the building and a warm zone facing the inside of the building. Further, the undercut section (112) in the mounting frame (110) is positioned close to the insulation member (not shown) than to the longitudinal slit (100d) resulting in good insulation between the box and building.

[0053] In yet another embodiment of the present invention, the stability anchor (106) is comprised of at least two portions, the bottom portion (106b) and the top portion (106a). The top portion (106a) comprises of plugs (122) or bolts (118a, 118b) extending through the top wall of the box. The auxiliary piece (126) is positioned outside the box and is configured to couple with the bolts (118a, 118b) or plugs (122) and is further configured to rigidly fix to the building with a slanted slide (126a) where the box (100) is installed. More specifically, the auxiliary piece (126) couple with the bolts (118a, 118b) or plugs (122) extending outwardly and the slanting side (126a) of the auxiliary piece (126) coupled with the lintel (128). Further, distance holders (124) are provided around or next to the plugs (122) or bolts (118a, 118b) in the outer wall of the box wherein the distance holders having a compression resistance superior to the compression resistance of the outer wall of the box in a longitudinal direction perpendicular to the wall part of the box.

[0054] It is clear that the assembly of box and mounting frame in accordance with the present invention allows for some important benefits, such as mounting and rigidly fixing the box on a mounting frame without the need to open the box, thereby sparing the effort of removing example given, insulation provided in the box for fixing the box to the mounting frame. Additionally, the set up of a clamp receiving a foot portion of the stability anchor, allows for removing the anchor without unclamping the box from the mounting frame and hence without removing the pressure on a seal provided between the outer wall of the box and a structure (eg window frame) to which it is fixed. Additionally by providing stability anchors made of at least two releasably coupled parts, a bottom portion of the stability anchor can be removed from the box, without releasing the connection between the outer wall of the box and the mounting frame (lever-clamp connection) and without disrupting the connection between the top portion of the anchor and the masonry or lintel, as such preventing disrupting insulation between the outer wall of the box and the building.
