Transfer units and hatches
Vertical and horizontal sliding hatches
A hatch gives you an opening that shuts and locks rather than a permanent gap in the counter. Both versions are made to order, so the hatch suits the run of counter it sits in.

Should I choose a vertical or horizontal hatch?
Both have the same glazing, lock and steel framing. A vertical hatch slides up and a horizontal hatch slides sideways, so the choice depends on the space around the opening.
