Defining the
last 12 years

Roto TSL 20

Roto has recently rolled out a new
version of its TSL Twin-Cam Security
window lock. Amazingly, it’s 12
years since the original lock came
along and saw a new revolution for
security on casement windows.
»»Stephanie Wright,
Clearview Editor recalls when
working as Marketing Manager
for key hardware distributor
Avocet Hardware, how this
creative window locking system
raised some eyebrows, but soon
got the sceptic’s converting over
from shootbolt systems.
“The public at large may not
really have been aware of it, but
it certainly made life a lot easier
for fabricators who were smart
enough to adopt it from the
start. The word used at the time
for the lock was: “revolutionary”.
I recall, after experiencing an era
of shootbolt locking systems, the
Roto TSL lock, which could be
fitted to a window as quickly and
easily as an espagnolette, really
did provide the highest levels of
security.
“At the time, shootbolts were
the favoured locking device
and mainly every window sales
rep in the country had been
brainwashed to tell members
of the public that their window

hardware& security

would only be any good if it was
fitted with shootbolts.
“Of course, there was some
form of reasoning behind this,
when the BS 7950 standard
(equivalent to EN Resistance
Class 2) was introduced in the
UK, standard espagnolettes
with two or three locking points
simply weren’t strong enough
to withstand the mechanical
loadings in the test.
“We’re talking about forces of
3 kN trying to push the window
open. That’s like angling the
window face down and having
the weight of three burly men
standing on it. No wonder some
of those very old basic espags just
gave way under that load.
“At the time it would have
been easier if Roto had carried
on selling their shootbolt
system, but thankfully for us
as distributors, they decided to
take a calculated risk and put
something out that was both
familiar, yet utterly new at the
same time.
