Hi, We are Optimum Brasses Ltd, please visit our website, https://optimumbrasses.co.uk

We are an established British company of over 40 years and all of our brass and bronze hardware is cast in the UK. We ship world wide. All orders are polished, assembled and antiqued individually by hand and we offer plain, decorative, authentic and contemporary designs. Happy perusing :)

https://www.hafele.co.uk/en/ lots to choose from and good prices, but you need a trade account so DM me if you see something you like, next day delivery.

For sleek performance with minimum fuss, consider straight D-bar handles in satin nickel or polished chrome. They’ll stand out crisply against your dark panels and make loading and unloading quick and effortless.

I prefer knobs rather than handles, perhaps in a brass or bronze.

Recommend looking at Buster & Punch then at Dowsing & Reynolds (Handle brands)

You can browse a wide selection at Decor & Decor’s Handles UK section to find the exact length that matches your door widths

if you do go down the horizontal handle option, just be careful with corners and wall units next to tower units and walls as you don't want the door to swing open and then the handle hits/damages anything. you can get angle stops for blum and hettich hinges [don't know about other brands] that limit the opening to 90 degrees.
