TIE BAR REPLACEMENT KIT (TBRK)
Each eaves corner (90°, 135° and 150°) is
supplied pre-fitted with two standard cleats
(Georgian 90° illustrated).
1
Two pilot holes already exist in the next
piece of eaves beam – drill two more at
4.5mm diameter through the eaves beam
and the cleat and then securely fit the four
M5 x 12mm taptite screws.
2
Where the eaves beam sits against the
host masonry wall, it has a structural
moulding attached to the eaves beam.
This has three fixing positions cast into it
to allow attachment into masonry – choose
the hole that directly lines up with solid
masonry and drill a 10mm hole into the host
wall. Attach the structural moulding using
the M8x80mm anchor supplied. Silicone
seal the gap where the moulding attaches
to the eaves beam.
3
On the ground, away from the conservatory,
offer up the first pre-drilled starter bar. Onto
the ridge hanger plate fasten using the set
screws provided - do not over tighten.
4
Take the second starter bar and
similarly offer this onto the ridge hanger/
compression plate assembly. Lift the whole
“A” frame assembly and get ready to install
it in its final position.
5
Attach the starter bar using the nut, bolt
and spring washer (included in the kit) to the
eaves structural moulding. Finger tighten
the nut to temporarily allow the assembly
to hang.
6
To set the ridge use an “angle fix” - check
the starter bars are at the correct pitch.
Chalk/pencil a line on to the wall to mark the
pitch line.
7
Attach the ridge hanger/compression
plate to the host wall. Drill the plate with 2
x 9mm holes, then the wall with an 8mm
masonry bit and fasten into the masonry
using the two M6 x 65mm sleeve anchors
(or resin anchors) provided. If necessary,
use aluminium shims to pack out behind
the plate. Check the plate is vertical
and securely fastened. AT THIS STAGE
IT IS ADVISABLE TO CHASE OUT FOR
CONSERVAFLASH /LEAD FLASHING.
8
Loosen the “crocodile jaw” bolts on the
underside of the main ridge body – ensure
it is supported at the front whilst it is gently
guided onto the top half of the ‘crocodile
jaw’.
Note: The starter bar is NOT attached
(bolted) to the ridge body.
