MEASUREMENT AND ASSEMBLY MANUAL
2.1 MANUAL CONTROL
The length of the blind lintel is determined by the width of the window opening as follows: add minimum laying
2 x 200 mm to the width of the window opening and select the closest higher lintel length that is fabricated.
The design of the lintel should already include the manner of the future roller shutter control - whether manual
(by a strap) or electrical.
Either control option can deal with the minimum position of 200 mm; however manual control, especially when
controlling the roller shutter by a strap, the recommended length of the lintel position is on the side of the
control: 220-250 mm, considering the fact that the axis of the manual control is always in the axis of the
sleeve, which is usually placed in a 140 mm distance from the end of the lintel. It means that:
●if the lintel is positioned in a 200 mm length, the axis of the strap is in a minimum distance of 60
mm from the jamb face,
●if positioned in a 220 mm then in an ideal distance of 80 mm from the jamb face,
●if positioned in a 250 mm the distance is 110 mm.
On the opposite side (i.e. on the side of the lintel where the manual control is not located), the minimum
positioning distance of 200 mm has to be kept; and more, depending on the width of the window opening and
the selected length of the lintel, i.e.
that the position of the lintel above the opening need not be symmetrical.
2.2 ELECTRICAL CONTROL
If control is electrical, lintel can be laid in 200 mm and more (depending on the clearance of the opening and
the selected length of the lintel); the lintel is usually located symmetrically above the structural opening.
3. PREPARATION OF BRICKWORK BEFORE ASSEMBLY
3.1 MANUAL CONTROL
3.1.1 OPENING FOR SLEEVE
The axis of the opening for strap from the lintel margin is 140 mm on either side. If lintel is positioned in 200
mm, the distance of the strap axis from the brick jamb of the window opening is 60 mm, and if lintel is
positioned in 250 mm, the distance is 110 mm. On the opposite side (i.e. on the side where location of the
manual control is not considered), the minimum positioning length of 200 mm or more has to be kept;
depending on the width of the window opening and the closest selected length of the lintel.

3.2 ELECTRICAL CONTROL
3.2.1 CABLING
If the roller shutter is operated electrically by an electric motor (which is usually located in the roller shutter
shaft), a distribution box of electrical wiring shall be placed next to the lintel on the side where the control will
be installed. A groove for cable protector of 25 mm width and 15 mm depth is cut in the roller shutter lintel in
the height of the opening axis in the brick lining. A pocket for distribution box is milled next to the lintel in the
brickwork, intended for the distribution box of the wiring. The distribution box shall not be placed under the
lintel. Using gypsum, the distribution box is placed in the prepared pocket in the brickwork so that it protrudes
by 15-20 mm from the brickwork. In the opening for sleeve on the side of the control a hole for cable protector
is prepared in the thermal insulation of minimum diameter 12 mm inside the roller shutter box in which the
cable protector from the distribution box is placed and fixed by gypsum.

4. SETTING UP JAMB IN FRONT OF WINDOW FITTING
Slide the insulation into the space prepared for the insulation filling in the bottom part on either side of the
window opening. Use mounting foam to fix it. Cover the inserted insulation filling with a glass-fibre netting
pushed into the sealant with about 50 mm (ideally 100 mm) insulation filling overlap on both sides in the
bottom part, also on either side of the window opening.
5. MAKING GROOVES FOR GUIDE RAIL CASES
Grooves for guide rail cases can be embedded in the jamb, or fitted additionally.
5.1 EMBEDDING A GUIDE RAIL
Grooves are made in jamb before fabricating plasters and, whilst making them in a single-layer brickwork
(when the width of the lintel is identical with the width of the brickwork), the prepared groove in the marginal
bricks with a pocket can be used. In the structural opening jamb, in a 80 - 120 mm distance from the exterior,
the space for the future groove of a guide rail case has to be marked with vertical lines. From the space for
groove, in a 40 mm width, use an angle grinder with a suitable cutting disc to remove the glass-fibre netting
and cut out a 50 mm deep groove (only brick partitions to be cut out in marginal bricks). Plasters shall not be
fabricated before a groove is made and a case placed.

MEASUREMENT AND ASSEMBLY MANUAL
Adjust the length of the guide rail case so that the height of the case from the brush of the lintel plaster
moulding to the bottom part of the jamb was about 30 - 40 mm shorter. Place the guide rail case into the
groove and fit it into gypsum in three points. Underlay the bottom part of the case so that a gap remained in
about 30-40 m distance from the bottom part of the jamb for a windowsill, and leave the case 15-20 mm
protruding from the groove for plaster. The case must be in line with the plaster. The distance from the outer
part of the brick lining of the lintel to the outer part of the case is 85 mm with 3 mm maximum plus tolerance.
Align the case vertically in either direction. Once the cases are carefully positioned and aligned, and the
gypsum hardened, fix the case using mounting foam. Embedding the guide rails will significantly improve the
security of buildings against violent entry.
Caution! When fitting the cases, make sure that the part for placing the guide rail can be torn off!!!

5.2 VISIBLE GUIDE RAILS

can be fixed to rendered masonry and at the same time to at least 3 points in the upper middle and bottom
part on the window frame.

Is provided by company dealing with mounting the windows.
Window frame can be fixed in a roller shutter lintel and also in marginal bricks by means of metal fixtures and
wall plugs in space, beyond the insulation filling. Holes for wall plugs are located about 50-60 mm from the
inner edge of the lintel. The distance from the outer brick lining of the lintel towards the outer part of the
window frame is about 165 mm. The stated distance must be kept with maximum plus tolerance of 3 mm.

PHASE II
8. CHECKING PHASE I
Prior to Phase II mounting, keeping the horizontality of the lintel positioning has to be checked, as well as the
dimensions of the lintel position on the bearing wall, the length of the inner part of the lintel for fitting the roller
shutter holders, bearing holders, bearings and pulleys. When a lintel is placed for fitting manually operated
roller shutters, the length of the position on the side of the control is 200 mm, and the length from the brick
jamb towards the inner side insulation part is 130 mm. When a lintel is positioned in a 250 mm (for manual
control), the distance is 180 mm.
Checking whether the dimensions are maintained, and whether the window frame is perpendicular.
The distance of the outer part of the window frame from the outer part of the lintel brick lining has always to be
checked (for 165 + 3 mm roller shutters).
9. NEW MEASUREMENT OF ROLLER SHUTTER
Measure net width and height of window opening and use the smallest dimension measured.

13. FITTING A ROLL-UP CASING
The casing is locking on its entire height but partially stapled. Therefore you need to inspect the casing and
find out which locking devices can be taken out. Usually the eleventh slat from the terminal rail and the
eleventh slat from the suspensions do not have locks stapled. Take the first part of the slats with fitted
suspensions, put it into the casing and by means of suspensions fit it onto the shaft; centre it, fasten it and reel
a little. Insert another part and reel a little. Continue until the entire casing is fitted.
Reel complete casing, the terminal rail included, into the lintel as much as you can.
