Together with British designer Tom Dixon, D-Line have created FAT, a new line of hardware pieces. The Fat collection comprises a lever handle, key escutcheon and thumb turn, as well as a door knocker, pull handle, flush pull and door stop.

Like the rest of the d line portfolio, each piece is minimalist enough to be timeless in its design, its beauty coming from its rounded profile and inflated silhouette, rather than from superfluous details. 

Tom Dixon uses the word ‘fat’ to imply generosity and softness of form. The result lacks any trace of sharpness or angularity and is a collection of pumped-up pieces that are simply ‘fatter’ than the norm.

The Fat lever handle is enduringly crafted in the highly resilient AISI 316 stainless steel, a material preferred by d line and further enhanced by a 20-year product guarantee.

The collection is available in charcoal, electric blue, polished brass and our signature satin stainless steel.
