REAR WALL END ASSEMBLY
1.
Starting with the pack of corner bars split the tape holding them together and first identifies the 2 roof bars from the 2 sidebars.
The sidebars have one hole and one mitre, both at one end. The other end has no hole and is square cut. The roof bars have 4
holes in the flange and are mitred at both ends and in addition have a letter “R” written at the apex on the outside of the bar. N.B.
If your greenhouse is a painted one, the roof corner bars will not be marked with a letter “R”. They can be identified from the
sidebars as outlined above. (Key Point)
The bars are also handed so you must identify the left and right hand. Standing up; hold one side bar vertically in your left hand;
the other in your right. Rotate the bars so that the 2 bolt slots are facing in towards you, with the mitres at the top (inside view).
Viewed this way the 2 mitres should run down to each other. The roof bars can be handed similarly, keeping the bolt slots facing
inwards and the letter “R” to the top. (With a painted model, the top can be identified by observing the 4 holes in the flange. The
two holes nearest the end are at 50mm and 33mm centres. The 50mm end is the top i.e. nearest the ridge) On the outside you
can identify them by ensuring that the “R”s (indicating ridge) are at the top, the mitres will then run into each other.
2.
Slide the glazing beading into the 4 vertical glazing bars and the 4 corner bars, taking care not to stretch the material. Trim off
any surplus level with the end of the bars. N.B. The corner bars have 3 grooves to receive the glazing bead; do not put any in the
middle one. (Key point).
3.
Lay out the components of the frame on the ground as though you were standing on the inside i.e. with the bolt slots uppermost.
Ensure that, having correctly identified the roof from the side corner bars, left and right hands (see previous text) you have the
roof bars with the letter “R” (indicating ridge) at the top on the outside, i.e. towards the ground. (Key Point)
4.
Slide 2 bolts into each corner bar bolt slots (facing inwards) 1 at the top and 1 at the bottom. Put a nut on and lightly tighten,
leaving them approx. 50mm from the end of each bar. These will be used later in the general assembly.
5.
Starting at the apex (2 corner bars opposite each other marked “R”) slide 1 bolt into the other bolt slot i.e. the one that is facing
upwards and is set at 90
to the other – 4 above. (Key Point)
For the construction of this frame you require from the main box:
1 pack of corner bars marked “corner bars”
1 rear end pack marked “rear end”
1 rear end cill marked “rear end”
1 rear end horizontal brace marked “rear end”.
From the pack of fittings you need:
nuts and bolts
glazing beading and gusset plates – 1 large (ridge plate) and 2 small
(eave plates).
These plates are not in the pack of fittings but are taped up with the casement
stays elsewhere in the box.
