A Guidance on Selection of Hardware
Considering the range of profile systems, the degree of security demanded
and possible weather performance requirements, it is not intended to advise
on selection of either the style or type of hardware. However, in the
absence of any alternative performance requirements, selection should
take into account the recommendations contained in the appropriate Trade
Where windows / doors are to be fitted in coastal areas or heavily polluted
regions of the country, it must be expected that a higher risk of corrosion
exists. Selection must take this factor into account. We will be pleased
to advise on the choice of materials and finishes for these applications.
SIZE AND WEIGHT
Window / door sizes must be within the Applications Limits and selection
must be made in accordance with the recommendations down by the hardware
manufacturer, copies of which are available from FERCO.
A GUIDANCE ON MOUNTING OF HARDWARE
We will be pleased to give recommendations for mounting and adjustment
of hardware. When purpose designed jigs are available, we strongly recommend
use of these in order to save time and reduce the chance of inconsistencies.
Hardware with provision for adjustment must be accessible after the window
/ door is installed.
In general, screws are recommended and used; in certain applications
purpose designed screws are required. Incorrect head form or thread
type can cause premature failure of the hardware. Only fixings recommended
by either the hardware supplier or the screw manufacturer should be
used. Care should be taken to minimize the risk of corrosion arising
from electrolyte reaction.
