Typical Overhead Ironwork Support
Note: In installations where threaded droprods in excess of 500mm are employed it may
be necessary to provide additional support bars to ensure rigidity of the support structure.
Securing a Rack to a Wall
If the rack is to be positioned against a wall, attach two right-angled wall brackets to the
top of the rack and finger tighten with the provided M12 screws.
Manoeuvre the racks into position against the wall. Join the racks together with 12mm
nuts and bolts placed through the holes at the top and bottom of the side panels and mark
the wall through the holes in the top brackets.
Securing Rack to a Wall
Using an 11mm. drill bit, drill holes in the wall to a depth of 75mm and fit masonry plugs.
Fix the hex head screws through the brackets and finger tighten. Check that the rack is in
the correct position and tighten all fixings.
Attention should be paid to the fabric of the wall. Where possible, drill directly into the
brick and not into mortar. With panelled or partitioned walls, instruction should be taken
locally as to how the rack is to be secured. See site survey.
Follow the procedure for the rack base as described above.
