Medium duty (Topaz), heavy duty (Sapphire) and extra heavy duty
(Emerald) use the same covers and closed / ventilated clips

Covers can be installed either by resting directly on the ladder side
rails (closed covers) or raised above the side rails providing a gap for
air to circulate (ventilated covers)

Covers up to 450 mm wide have a flat top surface and are simply butt­jointed together. Covers 600 mm wide and above are overlapped and
bolted together to increase their rigidity. Covers 750 and 900 mm wide
have a stiffener fitted along the joint for added rigidity

All covers are 3 m in length and supplied with six cover clips and
associated fasteners

For ordering information, see p. 23

Covers

General

Before fitting the covers ensure
a minimum clearance of 30 mm
between the ladder and the vertical
support face. For access to fit
cover clips a larger clearance is
required when the vertical support
is a solid face

Closed covers

Place each cover over the ladder
side rails and push the clip under
the side rail return flanges before
fitting and tightening the fasteners

Ventilated covers

Slide the clips over the top return
flange of the ladder side rails and
place the cover over the clips. Fit
and tighten the fasteners

■ Dimensions and weights – covers

Widths 750 and 900 have two additional 18 x 8 slots and Ø 9·5 holes to
accept stiffener for added rigidity

■ Dimensions and weights – clips

Weight: 0.5 kg per 4 clips

Weights

All weights given are in kilograms (kg) and are for 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

Closed covers

To fit covers as closed, fit the cover over the fitting side rails and place
the cover clips in position under the side rail return flanges. Fit and
tighten the fasteners

Ventilated covers

To fit the covers as ventilated, slide the clips over the top return flanges
of the side rails and place the cover over the clips. Fit and tighten the
fasteners.

Joining covers

When wide (600 mm or over) covers are fitted, the fitting cover may join
to either end of a straight length cover

If the straight cover has an overlap tongue, push ‘U’-shaped retaining
nuts over the holes in the tongue. Fit the fitting cover in position
overlapping the tongue. Insert fasteners through both covers and the
retaining nuts and tighten the fasteners

For 750 and 900 mm wide covers place the stiffener on to the top cover
along the joint before inserting the fasteners

If the straight cover has not got an overlap tongue, fit four ‘U’-shaped
retaining nuts over the holes in a joint strip and position the strip under
the butt-join between covers. Insert fasteners through each cover and
the two aligning holes in the joint strip and tighten the fasteners

For fitting a stiffener (covers 750 and 900 mm wide) refer to paragraph
above

Note

It may be necessary to drill holes in the straight cover if it has been cut
to length
