wall support brackets
150125100
Wall support brackets are an effective way of fixing any width of ladder, running either vertically or horizontally, to a vertical support
Wall support brackets are available for all ladder ranges and supplied in pairs with bracket to ladder fasteners
Installation (typical)

Fastener finishes
For ladders with G, D and E finishes, fasteners are high tensile Grade 8.8 hot dip galvanised
For ladders with S finish, fasteners are corrosion resistant stainless Grade A470
An alternative material for fasteners may be required depending on the installation environment – contact us on +44 (0) 845 605 4333

Assembly
Holes are provided for M10 setscrews – length and finish to suit application
Fixing brackets to supports
Only one fastener is needed to attach each bracket to its support ; three attachment holes are provided to give flexibility when positioning the ladder run
Fixing brackets to ladder – vertical runs
When installing ladder runs vertically, the full quantity of fasteners must be used to attach each bracket to the ladder
Fixing brackets to ladder – horizontal runs
When installing ladder runs horizontally it is often easiest to mount the lower brackets to the support, lift the ladder into position then mount the upper brackets. This procedure is especially useful for single person installation

Weights
All weights given are in kilograms (kg) and are for a pair of brackets in hot dip galvanised G finish
To obtain the appropriate component weight in other finishes, multiply the given weight by the following factors :
Deep galvanised (D) x 1·07 Stainless steel (S) x 0·94 Powder coated (E) x 0·97
Safe working loads
Vertical ladder runs
For a vertically mounted ladder installation, the maximum safe working load is 300 kg per pair of wall support brackets
Horizontal ladder runs
For a horizontally mounted ladder installation, the wall support brackets should be pitched at 2-3 m intervals so that the limiting factor for safe working load is the span between brackets and the ladder width rather than the brackets
Key : Replace the letter shown in red with your choice from the
following options :
F = Finish : G (hot dip galvanised after manufacture)
D (deep galvanised) S (stainless steel) E (powder coated)
All dimensions (mm) are nominal
