■
Coordinate suitable hardware combinations and installation procedures in windows and balcony doors with the
hardware manufacturer and profile manufacturer for the areas listed above, and conclude a separate agreement
for them.
INFO
The hardware manufacturer’s specifications on the combination of hardware (e.g. the use of additional
scissor stays, the design of hardware for burglar-inhibiting window sashes and balcony door sashes) are
binding.
Opening restrictor
Positioning and rebate clearance
■
All Roto FS Kempton opening restrictors are designed to be installed between two parallel, fixed surfaces whose
dimensions correspond to the specifications in this document.
■
The scissor stay space between the sash and outer frame or upstand must meet the requirements for opening
restrictors defined in this document (see drawings) .
■
The closer the opening restrictor and the friction stay are to one another, the larger the sash opening angle;
accordingly, installing the opening restrictor further away from the friction stay reduces the opening angle.
Using the opening restrictor
Depending on the rigidity of the window sash, one opening restrictor at the bottom or two opening restrictors (at the
top and bottom) may be used for Side-Hung sashes. For Top-Hung sashes, two opening restrictors must always be
used as required.
INFO
The opening width depends on:
■
the positioning of the opening restrictor,
■
the friction stay used,
■
the sash size,
■
the window profile.
■
The window profile must match the requirements of the opening restrictor.
■
The opening restrictors must be fitted on both sides (Top-Hung) or at the top and bottom (Side-Hung).
INFO
If there is insufficient space available for installing opening restrictors and friction stays, Roto provides
assistance with the generally recommended profile assessments.
