Rated 5 out of 5 by from Great replacement handle Sturdy. Well made. Easy to fit and does exactly what it says. I would highly recommend this brass replacement casement window handle. Would be even better if it came with 2 keys though.

Rated 4 out of 5 by from Casement locks They are a sturdy brass construction and do the job. If anything they are a bit heavy (being brass) but are certainly solid. I have had no issue with them. Possibly could come with two keys is my only criticism.

Rated 1 out of 5 by from Not Fit For Purpose. As an experience maintenance engineer I judge this product to be "not fit for purpose". The pivot in the handle become loose on the first closure the location pins cast into the handle break off without them performing their function. I wasted my valuable time on this product. This is the first negative review I have ever given Screwfix in 10 years. I intend to take the three casement locks back to the nearest depot in Bangor, they are not worth the postage to return. I expect my money back.

Is this product suitable for timber windows with integral weatherseal ?

Thickness of weatherseal (draught proofing strip) is about 5 mm.

Do these locks operate using a universal key or does each lock have its own unique key.

Hi, why does this fastern come with 2 latch plates ?

Asked by: bertlcfc
I think Product Support may have misunderstood the question. There is no way you can use both of the supplied plates with this handle. I could be wrong, but I think the reason for the two slots in the handle is so that the window can be locked fully closed or slightly ajar to allow ventilation. As for the two latch plates, these have slightly different base profiles, so I guess they are intended for two different types of frame... I can understand the one with the flat base, but the other one is thicker along one edge and has two small pips... strange?!?! A brief instruction sheet would be useful.
