Brass Thumbturns For Slide Stays.

What it says above, really!

These are to replace ones that have been "borrowed" over the years.

Crittall Gravity Catches For Sliding Sashes.

Yet another oddball item.

The request from the customer was "do you know what these are?".

My reply was "Yes, but they are all gone".

Fortunately, they wanted more than a handful - so we re-made them.

These date from many years ago - the last of them were in Tote Tins, with the original part numbers on - 05.00039.51 and 05.00040.51, so if you come across anything like this - you'll know where to get them from!

It's a clever idea - you lift the bottom sash and they bump into the projection - to release them, you push the little knobs to the side and then you can carry on lifting the sash.
When you pull the sash down, it pushes the triangle part back and re-sets for the next time you use it.
