Fab & Fix Sash jammers are with out question in our opinion the best sash jammers on the market – After all Fab n Fix invented the Sash Jammer they didn’t patent it and now every man and his dog has ripped it off so be aware there are some awful copies out there ,that just wont do the job
As reactive locksmiths we have fitted 1000’s of these as many years ago before Multi point locking systems were readily available we used to secure doors with these whilst we sourced a new locking system or an actual door ( of course thins have moved on now from the 80’s and multi point locks are more freely available.
point trying to make here they are a great extra security item and we now fit them as extra security on all upvc doors and windows – we have witnessed many attempted break ins (especially on vulnerable french doors) where the door has tried to be forced or spread open and the sash jammer has saved them .
we have also witnessed where the cheap rip off alternatives have been fitted and they have failed i.e. either snapped or been ripped out from the frame. ( if you buy the ket version the Fan & Fix sash jammer comes with all fixings /lock and packers the fixings are suitable for either hollow Upvc frames as you can use the jack nuts supplied or if you have a metal frame the screws are more than adequate ( you will know this when you drill your pilot hole..
