L and T handles are still a great choice for a cabinet handles – especially where there is plenty of space for people to pass or where their extra convenience is valued – or where it is important to match an existing installation.
Swinghandles on the other hand are preferable where passageways are narrow so that clothes do not catch, or where transit damage needs to be avoided – they are probably more modern and offer lots of useful options. These days both types are available in polyamide, zinc die or stainless steel – so the choice is open – it is a question of style and space.
