The Repeater affixed to its wall mount
brackets should be fixed to a solid wall (these
include brickwork, blockwork, and concrete.);
due to the weight of the Repeater, fixing to a
hollow wall is not recommended. Always
check that there are no pipes or cables hidden
in the wall beneath the area to be drilled.
Various pipe and cable detectors are available
to check this.
To provide secure fixing to a solid wall, the
most common method is drilling and
plugging. The size of fixing is dependent on
the item to be fixed and the nature of the wall, The Repeater should be fixed with mild steel,
M6 (x 50mm to 75mm) rawlbolts or similar.
First mark out on the chosen wall the fixing centres of the repeater (see above.).
Mark and drill the wall with the correct size masonry bit
as specified by the fixing manufacturer.
It is good practice to wear goggles to protect your eyes
from flying debris when using power tools.
Hold the drill bit against the mark and begin drilling
slowly so that the bit does not wander from the position.
The wall should be drilled to a depth which is sufficient
to accommodate the full length of the fixing.
Insert the fixings so that the top of the sleeve/anchor
section is level with the wall surface, gently tighten the
bolt by hand so that the anchor section of the fixing
expands and grips the inside of the hole.
As the bolt pulls its way in, the sides of the anchor section are
forced outwards, gripping the surrounding surface.
When all four fixings are in place,
carefully
withdraw
the
bolt
sections and offer up the Repeater to
the wall. Great care should be exercised here as the
repeater is very heavy.
When the Repeater held in position against the wall in the
chosen position (a suitably rated heavy duty scissor
lift table/trolley may be suitable for
this operation) carefully insert the
fixing bolts through the mounting
lugs of the Repeater and into the
sleeve/anchor sections of the fixing in the wall and
tighten the bolts.
M6 rawlbolt of the type recommended to fix
Repeater and mounting plates to a wall.
