• The ladder must be dimensioned so that the topmost rung is
located ± 100 mm above the eaves or other access platform.
The bottom rung must be located 1,000–1,200 mm above the
ground or other departure surface.
INSTALLATION
Distance to the bottom
rung: 1,000–1,200 mm
Maximum distance between the pairs
of wall ladder legs: 3,000 mm
Minimum distance between
the rung and the nearest
protrusion: 200 mm
200,0-1200,0
NOTE! If a safety rail is fastened
to the ladder, at least four pairs
of wall ladder legs must be used!
• The wall ladder legs must be dimensioned so that the distance
between the center line of the ladder’s rungs and the eaves or
other protrusion is at least 200 mm. The legs are to be shortened
to a suitable length, if necessary. The wall ladder legs must be
fastened to the wall material with the aid of a suitable fastening
method. While fastening the ladder, measures must be taken to
prevent water trickling down the wall from entering the wall
structures by, e.g., sealing the seams between the cladding and
brackets.
• The wall ladder legs must be fastened to the ladder with wall
ladder clips so that the topmost pair of legs is located as close to
the eaves as possible and the bottom pair of legs is located
between the first and second rung. Efforts must be made to
always fasten the wall ladder legs to the load-bearing structures of
the wall. In the case of brick-cladded houses, it is advisable to
install the wall ladder legs in the frame structure before bricklaying.
The maximum distance between the pairs of wall ladder legs is
3,000 mm. The wall ladder clips are fastened with two M8x16
screws and one M8x40 screw.
• The wall ladder legs are fastened to the eaves structure with the
aid of eaves supports. Eaves supports are to be used when the
length of the wall ladder legs exceeds 400 mm. The purpose of
the eaves supports is to support the ladder during vertical loading.
The eaves support is fastened to the wall ladder leg with an
M8x30 screw and to the eaves with a 7x50 self-tapping flange
screw.

• The bows are fastened to the roofing battens/auxiliary battens
with an L-shaped bow fastener.
• The L-shaped fastener is fastened to the bow with an M8x40
screw and to the roofing with a 7x50 self-tapping flange screw.
An EPDM rubber seal must be installed between the roofing
and the L-shaped fastener.
• The bows are fastened to the roof ladder with a U-shaped
bow fastener.
• The U-shaped fastener is placed around the ladder’s rail
and secured with two M8x40 screws and nuts.
• The bows are installed to a tiled roof with the aid of a bow fastener kit.
• The auxiliary batten fasteners (2 pcs) included in the bow fastener kit
are fastened to the auxiliary batten with two 7x50 self-tapping flange
screws. The timber strength class of the auxiliary battens must be at
least C24. The auxiliary battens are to be fastened to at least three roof
trusses using two 6x120 screws for each roof truss.
• The fastener interval is approximately 300 mm.
• With the aid of the adjustment openings, the connector can be aligned
with the bows in the direction of both the pitched roof area and the ridge.
• The connector is fastened to the auxiliary batten fasteners with two
M8x16 screws. The bows are fastened to the connector with two M8x40
screws.

• When installing the roof ladder, it must be ensured that it is aligned with
the roof walkway.
• The bows are fastened to the roof walkway with a separate connector.
• The bows are installed at the top of the ladder and secured with
an M8x40 screw and a nut.
• The wall ladder must be installed so that the lowest part of the bow is at
the same level as the bottom of the roof walkway.
• The bow connector is to be installed in its place at the bottom of the
roof walkway so that it is aligned with the bow.
• The connector is fastened to the roof walkway with two M8x16 screws
and nuts.
• The connector is fastened to the bows with two M8x40 screws and nuts.

All buildings must be provided with a safe access to the roof and safe passages to the ridge, chimney,
hatches, and other structures requiring maintenance. A safe descent from balconies and upstairs rooms
must also be ensured.
Buildings that are more than 9 meters high must be equipped with fastening structures for safety ropes
(Finnish Ministry of the Environment Decree on the safe use of buildings, 1 January 2018). In the case of the
Pisko SafeGrip ladder, fall protection can be carried out with the aid of the Pisko vertical safety rail.
The wall ladder and its fastening must withstand, without damage, at least a 2.6-kN vertical point load and a
2.6-kN vertical overall load per each two meters of ladder. The bow of the wall ladder and its fastening must
withstand a horizontal outward-directed minimum load of 0.5 kN (RT 85-11132).
The Pisko SafeGrip ladder meets the abovementioned requirements. In addition, in accordance with the
dimensioning requirements, the clear width of the ladder rungs is 400 mm and their distance from each other
is 300 mm. The ladder is manufactured from hot-dip galvanized steel tube. The side rails are made of oval
25x45-mm tube and the rungs are made of roughened 25-mm tube. The rungs are attached to the side rails
via riveting, while the other joints are screw joints.
Fastening the Bows to the Ladder Frame
USE
• The bows are fastened to the ladder frame with support arcs.
• The contracted end of the support arc is pushed inside the bow’s
roof-side end. The coupling is secured with an M8x40 screw.
• The other end of the support arc is fastened to the ladder frame
with the wall ladder clip and secured with two M8x16 screws and
one M8x40 screw.
Installing the Anti-Climb Guard
The anti-climb guard is used when it is desirable to, e.g., prevent small
children from climbing the ladder.
• The anti-climb guard is placed on the ladder frame so that it covers the
lowest rungs. The anti-climb guard is to be pressed lightly downwards
until it is securely in its place.
• The anti-climb guard can be locked to the rung with an Abloy padlock
(no. 340, tall), if necessary.

MAINTENANCE
When installed in accordance with the instructions, the Pisko ladder and roof safety products are durable and
safe to use due to the continuous quality control and research work conducted by Piristeel Oy.
In order to ensure the safe use and durability of the products, the property owner must perform the annual
inspection and maintenance procedures and ensure that the snow load stipulated in the regulations is not
exceeded.
If a vertical profile has been installed in the ladder, the owner of the property must have it checked annually
by a person authorized by the manufacturer.
• inspecting the tightness of the joints and fastening points
• checking the wall and roof fastenings
• checking the watertightness of the lead-ins in the roof
• taking care of the removal of excess snow in order to minimize the loading of the structures and
fastening points (several times during the winter, if necessary)
• removing snow and ice from the ladder, if necessary
• checking the condition of the paint or zinc coating of the products, as well as repairing and touch-up
painting local damages
• replacing or repairing damaged or defective parts as soon as possible.
